The 'problems' with the 5.7 and 6.2 GM Diesels can be easily remedied. ARP studs and a fuel/water separator vastly improves reliability for both engines. The 6.2 took off from where the 5.7 Olds left off, still utilizing a Stanadyne mechanical fuel pump best suited for tractors, but does alright for automotive if you take care of it. Boost a 6.2 with a turbo for more power, just make sure to build up the top end with high compression copper gaskets, and replace the head bolts with hardened studs, and add a block girdle to add some block strength.
I'm gonna have to go against the 6.2 detroit diesel being unreliable. My dad still has one in a 1983 van and it has now done over 800k miles and we have not cracked open the block once. Only regular filter changes and fresh oil will keep it running forever. If anything the body will rot away way before the engine dies :D If you want to talk about unreliable diesel engines, we can talk about the 5.7l Oldsmobile V8 diesel, now that is a crappy engine.
JackPecker911 I agree with you. I own a 1995 K3500 Dually with the 6.5 turbo which I beat the hell out of as a work truck, and it never wanted to stop. This guy said don’t “overload them” I towed over 15,000 LBS in that truck through the mountains with no trouble. I also own a Civilian Blazer with a 6.2 Detroit from the factory, it’s a 1984 model. The truck has 385,000 on it and still going strong. They’re good motors, they can pull well ( a little slow off the start but can get up to speed ) they’re reliable, and they make great fuel mileage. They were also the first diesel out of Ford/Chevy/Dodge. Chevy in 1978, Ford in 1983 Dodge in 1989. Detroit is an all around good diesel and apparently this guy has no idea what he’s talking about because they’re great motors.
years ago I had a buddy that had a 64 Chevy with a Detroit 4-71 engine swap. It smoked like a train but it was freakin cool. Love the sound of a DD 2 stroke.
The 6.2 Detroit Diesel engine is far from a bad engine. They are a lower performance Diesel engine but they are extremely reliable as long as you take care of them. It’s not a 5.9 Cummins, you can’t beat the living hell out of it it’s whole life and run it a gallon low on oil forever and expect it to last. But it’s not bad. They are a cheaper priced Diesel engine because of the lack in power and the fact that most of them sit in the old 80’s Chevy square bodies that are almost always rusted out. But I can say from experience that although your not gonna be winning any drag races anytime soon you will have a decently efficient and reliable power plant.
Collier 620 I want a square body, but they're do expensive compared to 12v cummins. That and I do want a crew cab, so that's probably also why they're so expensive. I was trying to find a cheap and reliable diesel truck.
Jürgen Von Parsberg 12v Cummins is a true diehard. It’ll outlast anything else out there. I love the 6.2 but it’s just not a 12v. There simple, reliable, and if you can afford one with a 5 speed, go for it. It won’t let you down as long as the trans hasn’t been abused badly, stay away from ones with automatics tho. That trans was way under spec for the torque of the Cummins. And yeah, the crew can square bodies are getting hard to find especially if you don’t want a dually. Personally out here in Kansas I’m looking for a good 12v truck but the cheapest ones are rust buckets that people want $5,000 for. I’d love to get an 80s suburban with a 6.2 and daily it
JBat5202 true there. I’m kind of doing that anyways, looking for an old 6v92 or 71 Detroit to put into something just for the hell of it. That’s gonna be a long project but it should be fun
The Isuzu 2.2 liter was one of the best Diesel engines Japan has ever made. Japan rocks the light duty and medium duty truck market with the Isuzu built Duramax diesel line up.
Japanese can build proper diesel engines, and they are already doing it since the 70's. Toyota, Isuzu and Mitsubishi all used to make great diesel engines that are still going strong to this day. The problem with new diesels isnt exclusive to the japanese.
@meteorbdragon100 yes man I am from Indonesia I have 1991 Isuzu panther with isuzu c223 engine non turbo diesel it is very slow but very reliable it has 762.000km and it's still going fine with no engine problems
Liam O'Sullivan Haha that would be ok for a gasser , but if a diesels doing that it could be a bad injector to a dead hole.. besides it’s so shitty, shut it off and fix it
I have a 1998 K-3500 with the Detroit 6.5 turbo diesel that I use to tow a loaded three axle bale trailer. 321,*** miles and still going strong with some minor upgrades and modifications such as marine fuel injectors, a relocate kit for the PCM, and upgraded head studs. I am only 15 and I bought it at 14 when I got my farm permit and I have already put 30,000 miles on it. That truck has been a real workhorse for me.
IDK. Uncle had a 6.5 turbo towed everything he wanted to pull. Cuz had a 6.2 in an old suburban years ago. Slow as all hell. But got 20-23mpg towing a ski boat. That's no bad.
I've got a legacy diesel and it's brilliant - bought it off the back of a load of customer reviews. Only downside is expensive parts. Never had any problems
This entire movie was discredited by the fact that the 6.2 and 6.5 Detroit for General Motors line of trucks made this list. While not power houses they're reliable. But the movie got one thing right here. They get really good fuel/oil mileage. Notice I said fuel meaning diesel and then oil or waste motor oil. They weren't very picky about what they ate so long as you didn't expect them to eat water,gasoline or alcohol. They would run good on waste oil so long as you filter it beforehand. And as a farm boy and exfarm hand I learned that was extremely handy. So long as you maintained them properly they keep going. As a matter of fact I know most of them in my small hometown are still doing the same job that they were when I was a teenager. It is 2018 I'm 32 now and at least two of them are older than I am. There just a little Rusty'er from the last time I was in them. Haha
Brentelec I had a 6.5 in my 1995 K3500 dually. Say what you want but I beat the shit out of that motor as a work truck and it just kept going nonstop. I towed over 15,000 LBS with it and it seemed to have no trouble with it, this guy is just going by the stats of the motor, not what it truly can do.
The 6.2 Chevy diesel is one of the best motors ever made, it is durable as hell! The 5.7 DX diesel will keep on running if you drive it in the right way and maintain it!
Back in the day my neighbor bought one of those GM diesels and lived to regret it. As far as the Ford Powerstroke goes, most buyers rued the day Ford retired the half-million-mile International 7.3 for the new PoS!
Two examples of a good diesel, Fiat's JTD, used in the Tempra, and believe it or not, the Austin-Rover/Perkins L-Series Prima turbo diesel, as used in Monetgo/Maestro and beyond. Both were powerful direct injection turbo diesels at 2 litre. The Perkins/Rover unit was especially solid.
“The Japanese just can’t make a reliable diesel engine”... hold on there sunny! Isuzu is Japanese and they are arguably the worlds best diesel engines. Nissan is also an excellent engine manufacturer. Fuji Heavy Industry (the parent company of Subaru) makes many high quality diesel engines. Mitsubishi is another excellent diesel engine manufacturer. I think you’re smoking a bit too much hash with your statement.
On the LF9 GM diesel, where i grew up they converted them to gas and made drag racers out of them. They were great, since you almost couldn't kill them with power. I lived in Michigan, where most of the car disappeared after a few seasons, so getting them cheap was not a problem
I have to disagree with the Japanese diesel engine part, especially Toyota because one of their diesels, the KD series used in Hilux and Hiace (and in a certain compact MPV sold in Southeast Asia and parts of the UAE), has a rock solid reliability. Isuzu also made extremely reliable diesel engines, some of which can run well past a million kilometers without much trouble.
Yea. Here in finland there was news article about KD series. They dont anymore take engines of from crashed cars because ten year old ones are still in the storage collecting dust :D
ScoutSpyScout gotta agree with that. The standard 2.5 liter 2KD only made 100 hp and 147 foot pounds (non-intercooled turbo ones with manual, automatics have slightly higher torque at 191 foot pounds) with its latest iterations with VGT topping out at 142 hp.
Another worst Diesel-engine ever is made by a japanese-american company: Isuzu. The internal called "6DE1" or "DMAX V6" engine was used in Opel/Vauxhall Vectra C, Signum, Saab 9-5 and Renault VelSatis and Espace. Only a few of those engines passed 100.000km/60.000miles without a broken engine or broken diesel pump. The liners were likely to slip down. Exhaust gases are pushed into the cooling system then. The engine runs hot. Some mechanics diagnoses that the head gasket is blown. But in 99% the liners are broken. The Denso high-pressure diesel pump does not like biodiesel. The valves break down. You should fill up premium diesel (without biodiesel) only OR with normal diesel you should put a bit of 2-stroke-oil in the tank every time you need to fill it up.
Isuzu don't make a bad diesel engine.. The mileages the old 4JA1 and 4JB1T (to name a few) can do are testament to that.. There is one in South Africa that has done over 1 million KM's- verified.
O yes, you have to put some miles on to wear through the hard chrome on the liners. The 4JB1T survived the lack of an intercooler well. They would boil the coolant and burst pipes long before the high egt's could think of cracking a head or melting a piston. I would get overtaken by a 4JB1T with a caravan behind it on the way back to Johannesburg from Polokwane whilst I had a 4JA1 doing the speed limit at full power. An hour later I would pass them stranded as they had blown the cooling system and it steamed like a volcano next to the motorway. But that motor shredded the tranny if not driven responsibly. Have a lot of respect for that motor. The sub is still in production, they have efi fuel injection now and I presume some head changes (Have not researched) GM have refined a timeless classic.
I’m going to disagree with the 6.2 and 6.5. I’ve had a 6.5 in the past. Like you said, it’s an economy diesel with torque and horsepower coming in at low rpm. It’s not that they can’t tow, it’s that they can’t tow where you’re showering down on them. Their peek efficiency is around 1800rpm. As far as their problems, the marine industry has the solutions for most of them because of their popularity for ship generators, not to mention their military applications.
Our Hi Ace D4D 3ltr diesel, over a million kms trouble free, only ever injector serviced once and the inlet manifold cleaned out once, damn good reliable strong engine!!!!
Own diesels of the Honda are not bad at all. And mind you, the Japanese have been making diesels not just for passenger cars but for light and heavy utility vehicles as well. And they are excellent in their own manner.
I'm honored my 6.5 Chevy Turbo Diesel made the list. The main problem is the PCM change that at some pointe. my truck is a chip box easy dump with a chipper towing Alway 10000 plus pounds.
Actually, I've had very good service from the GM diesels I've owned. 5.7, 6.2, 6.5, 8.2 all have served me well with no issues. I also now how to properly care for and operate a diesel engine
Yep, my band's first van was a Ford with the 6.0 diesel. 2004 with 120k miles, bought in 2012. Problems we had: EGR valve failure, alternator failure which killed the FICM as well, significant fuel leak in two places, and finally, EGR cooler failure which put coolant through the motor. Engine is near impossible to work on in a van... 0/10 would not do again.
Japanese can't make propper diesel enigines? Apart from the one you mentioned all of the big diesels in the Toyota Land Cruisers for example are great and some of the most reliable engines in the world when maintained propperly. With a bit of care the 6 Cylinder-Diesel Engines like the 1HD-T, 1HD-FT or the 1HD-FTE run for litteraly millions of kilometres.
Amen the landcruiser engines are something else there’s a 1hdfte I know of that has 2milion ks on it and it has had nothing done to it I have a hdj79 with a 78 and it has 380000ks on it hasn’t had a single issue either. All of the American diesels seem to have all the issues.
Japan makes very good everything they are innovators while other country's like Germany invented diesel. For example kubuta diesel very great engine Japanese etc more ,,,,
Chaminda Thushara Ruwan I can say Toyota and Honda are good except Honda has problems with its transmission Mitsubishi has the best warranty 10 years on their car. Nissan don't know Isuzu must be good they partnership with gm to make Diesel engine. Mercedes om606 best diesel nothing but the best
Also as being a 6.0 powerstroke owner and going to school as a diesel/ heavy equipment mechanic, i found that it really varies what 6.0 ya pick up. While being inexperienced and feeling invincible, I bought a 6.0, feeling like I could tackle everything it threw at me- The head bolts did not fail, I ended up deleting the EGR cooler, installing a fuel pressure regulator spring, replacing an icp (injector control pressure) sensor, installing stainless steel up pipes, and a turbo back 4" exhaust as well as an SCT livewire ts+ tuner running on the lowest (50 hp) tune that I still have problems- I never beat it up or run the rpms to redline, my heads are still fully intact, i'm not using up coolant, I have an injector going bad which i believe is the o rings on the injector as my start up and warm up exhaust is blue and I have a rough idle/ miss at times which follows the injector solenoid failing issue which in whole contributes to the amount of oil i/m using/ burning; I asked my co workers about this (who have 40 yrs experience in the field) and agreed with my diagnosis. Also, I have an oil leak which I believe (just looking up with a flashlight) is coming from my icp sensor again, a year later after replacing the old one which ended up being an o ring, I believe this one is either an o ring or the whole harness, regardless, i'll replace both. but the moral of the story is it depends on which 6.0 ya get- mine also has steering arm, tire rod, control arm bushings that are completely shot and haven't seen grease in years. The front end needs some work :) The Minnesota rust doesn't help.
a few mods can easily boost the reliability and then power of the Powerstroke 6.0's, but from stock, they are lacking. they do sound REALLY good too: the 6.0 is the diesel that made me interested in diesel performance in the first place my uncle had a 6.2 n/a, and though it was a sloth, it got 24 mpg on the highway with a trailer and a racecar inside it from the factory. no clue on how much the setup weighed, but it was reliable for quite a long time. he was astonished at the mpg it got but hated being stuck in the slow lane so he got a gas engine when the 6.2 needed servicing. the military has used 6.2 diesels for decades, and they are very reliable now, but thankfully, are being phased out for a much more powerful and capable Duramax engine.
"The LF9 wasn't a Rocket 350 turned into a diesel as many think, but some components were shared." Self contradictory statement. The reason the engines shared components was because that's exactly what GM tried to do - to make a diesel engine out of an existing gasoline engine design instead of starting from scratch like they should have. They did it because for a brief while diesel was significantly cheaper than gasoline, and GM was rushing to put something in production quickly.
They shared a few parts with the gasoline V8, water pump, valve covers, rocker arms and bridges, oil fill tube, rod bearings, exhaust manifolds and certain oil pans. Blocks are different and use the big block 3" main bearing crank journals, other parts unique to the diesels: heads, connecting rods, pistons, camshaft, lifters, pushrods, intake manifold, timing gears, lift pump, flex plate, starter, oil pump drive/vacuum pump.
The Ford-PSA designed 1.6L turbodiesel. It's called DLD-416 or DV6 and it's found in: Peugeot, Citroen, Ford, Volvo, Mini and Suzuki. The mode of failure is wear and tear: the oil pan design is poor and all the oil doesn't drain properly. As a result you have malfunctioning EGR, DPF fills up sooner than expected, valves get badly carbonized, turbo gets seized and overall the engine is just clogged with black burnt residue. If you have to buy one, get a low mileage one, double the oil change intervals, take the oil pan out sometimes (not just the plug) for complete cleaning and redline it properly once a day.
I love my 6.5 diesel it’s cheap af for parts and is like working on a 350sbc. I have a bigger turbo and it’s tuned. Makes good power for now 300k and counting
The 6.0 and 6.4 powerstrokes aren't bad engines per say but they were meant for schoolbusses and it was made by international instead of ford, the new 6.7 is made by ford and it is way better stock, and if you bypass the EGR on the 6.0, change the head gaskets and studs and o-ring the heads it's pretty reliable, the same procedure applies to the 6.4 but with another step and that is to delete the DPF, It's a shame the V6 tdi is a bad engine it sounds amazing and if we wouldn't get shafted here in sweden on taxes i would've gotten one
In USA some pending state legislation will make it a big monetary fine if you delete air pollution controls and your caught. Some state do check for them and if missing wont pass inspection
In regards to the VW Group's 2.5 V6 TDi, the original 150HP is the really problematic one and even then, it mostly applies to first years of production, which are also the engines with most fuel pump and turbo issues as well - or rather, were the ones, since most of them either died or had the problematic parts replaced. After that, the engines got considerably better in regards to reliability, although they still require considerable care. I have the AKE (132kW/180HP) in my car, changing oil every 7.5-10k kilometers (4.7-6.2k miles approximately, I think), not being cheap with the consumable parts (filters, timing belts, etc) and buying decent quality fuel, and I never had any real issues with the engine - approx. 370k km (230k miles) and some of it with short distances which is far from perfect for a relatively large turbodiesel (for european car).
Bullshit, the 1.9 TDI engines made before mid-2000 are bulletproof. For example the ALH 1.9TDI, found in Audi A3, Bora and Skoda Octavia MK1 is capable of running 600 000-700 000km without a major rebuild, excluding clutch and timing belt changes but those have to be changed anyway at some point.
haha, sure. 2007 Touran 1.9 TDI 105 at 140 000km it had to have its turbine, actuator, flywheel and clutch replaced. Plus it's a BXE which means it could put a rod through the block at anytime.
Not a big fan of v6 engines especially diesels they always have a rotten rattling sound but the 2.5tdi was a very good engine to me tbh. Sure I needed it cleaned up occasionally but I loved it!
WHAT!? Japanese can not make good Diesels? As a Renault owner you have to know that the 2.0 dCi in the Megane, Laguna ect. were troublefree and goodrunning Renault-Nissan-Diesels!
Sorry to burst your bubble about Renault- Nissan diesels, they were Renault designed and built engines that are great, Nissans own engines as fitted to the Pathfinder and Navara ect. are absolute Shit. Nissan diesels used to be great but not the newer ones with their timing chain snapping issues and oil leaks. I had a Nissan X-Trail 2-2 dci Aventura which as absolute crap, Nissans aren't what they used to be in the past, some people blame Renault for this but it wasn't the Renault engines that failed, the Clio 1-9 diesel I had in 1994 was one of the best diesel cars I've ever owned, fast and frugal it was great and did over 120,000 miles before I sold it.
As a prior owner of a high-mileage 6.5, I can tell you that they aren't bad engines, depending on what you need one for. They are meant for light towing/fuel economy at heart, not heavy towing. The 6.5 is bad about snapping the crankshaft under heavy load, and the 1995+ 6.5's are bad about the PMD going out. (pre-1995 engines do not have electronic fuel injection and are far more reliable.) If you keep these things in mind, and use it as it was designed, the 6.2/6.5's are very good engines. There's a reason the government used them for many years, including in the humvee's.
I must admit, that this VAG 2.5 V6 TDI is really unreliable, but damn, those engine sounds are like a piece of art! I used to have some experience with BAU coded engine (which supposed to have those camshaft and rocker problems removed). Those sounds were stunning, apart from knocking noise 60k km after :D
The GM 6.2/6.5 was not a bad engine, its weakness ( I ended up finding out from specialist Heath Diesel ) was the coolant system. The coolant distribution from the right side of the block to the left was imbalanced causing head gasket issues. I owned a 6.2 and it did the job.
I liked mine . It was definitely a dog though compared to a newer direct injection diesel. I actually replaced my 6.5 with a 6.2 block . It ran great with awesome fuel mileage.
We had a 6.5 turbo on a work truck and we flogged the hell out of it. Of course we had to replace pumps almost yearly but we frequently pulled 20k lbs with it and although it wasn't a fast truck, it got the steel where it needed to be. How did it make it to almost 150k miles? We were very meticulous about maintenance because the trailer was almost never unhooked and it was loaded to capacity or the truck idled waiting to be loaded. There really was no in between for that poor rig.
Some of the engines I can think about: -1.9 Dci 120hp from Renault Laguna II -2.5 CRD from Jeep Cherokee ( each cylinder got it's own head and is prone to leaks ) -1.2 & 1.4 TDI - crankcase goes loose after about 150000 kms -2.5 TDI V6 - not to be confused with earlier 2.5 TDI inline diesel, which is good -early 1.5 Dci - when oil was changed with intervals taken from manual ( every 30000 kms ) the whole engine and especially crankcase could be destroyed quickly -2.0 TDI PD - head, head gaskets, pistons and oil pump failures. Not to be confused with later 2.0 TDI CR -not exactly bad, but engineered to make owner pay more - BMW N47 diesel, with cam belt going loose quickly, accompanied by its placement near gearbox, necessitating in removing engine from the car About Japanese diesels - in fact I would say that most of them are good and some are very good: -2.2 CTDI from Honda Civic and Accord - no major problems -1.4 D-4D from Toyota - may suffer from DPF failures, but far less than other modern diesels ( additional injector in the filter ) -2.0 Dci from Nissan - used by Renault in Laguna III and such, no major problems -old non turbo 2.0D from Toyota and Nissan - slow, noisy but reliable - they are workhorses -1.8 DiD from Mitsubishi - no major problems
That depends which 2AD, the 177bhp version in the Toyota can be unreliable mainly due to head gaskets and DPFs however the 120 and 150 2AD FTV versions which don't have a DPF are reliable in my experience.
My dad have a 173hp (130kW) 2AD Avensis from 2008. With it chipt it has 200hp (150kW). He works most of the time and maxes out his overtime every month. He works at a place 50km from where he lives and have had NOT a single problem with that engine. He did destory a brake disc and brake pads in the back from ice build up. Had some normal wear like wheel bearings and stabilization arms. Like the worst thing to brake on it was headlight bulbs.... Pure pain to change them out :c Fule usage. 6.4L / 100km if you drive around 80-90km/h and is nice to it. But dad is not nice to it and likes to pull ahead of BWM drivers at stops lights that think they are something :/ (and also drives at 130-150km/h....) He average 7.1L / 100km. Calling it a bad diesel is just wrong... It is not thirsty fools. It is just a big heavy modern car. Mabye they have gotten worse? Anyways dads Avensis I have respect for. Very few modern cars I can say that to. 100km 5 days a week for 8 years now. In -39 Celsius to +32 snow, rain and mud. Before he own it it was a leasing car and had a ruff life with scraped rims and the gearbox was like if someone that did not know how to drive a manual had it before him. (first and second gear was a mess) but still works 8years later. Just have to be careful when it is cold outside. It as many miles on it. We are talking about 300,000km at least. I don't know for sure but due to it being diesel it will just keep running until old age catch up to it. That being soon :c
Had experiences for quite long time with an Oldsmobile (Custom Cruiser) 5.7 Litre V8 Diesel. It's confusing. Ours has never failed while it was in the family. With the original 3-speed Hydramatic transmission it worked comfortably till 90-100 Km/h. Some friends of ours owned few other 5.7 Litre GM diesels and most of those engines had failed. Options to keep them on the road as long as possible was/is the transmission replacement for a 4-speed automatic. As well as the engine replacement for the mentioned 6.2 and/or 6.5 Litre V8 diesels which were more reliable. With these modifications the top-speed could be increased safely till 130-140 Km/h. All in all 5.7 D was a weak engine and the only goal of it was the low fuel consumption for its size. The best and lowest average we had reached with it was astonishingly low. 8 litres per 100km.
The 6.5L and 6.2L Detroit Diesels should not be on this list... These engines have a reputation in the motor boat industry that is like the 5.9 Cummins in the Pickup trucks... They have been the only engines ever used in the US Military HMMVEEs and get any where from 21.5-29MPG.... The only problem with these engines is the way GM installed them in the vehicles, the accessories on the serpentine belt and the fuel systems are the problem, not the engine it's self... 6.5L and 6.2L never had their "common problems in the non-civilian road vehicles they were installed in.
@Corn Fed Owned a 6.5 (1999, last year for civilian models) for almost 4 years, never had that problem but I've only put about 25k on it. Glow Plugs are old, though.
Ty Bailey We love ours. Kinda pissed at Ford though for replacing the same faulty part in instead of a new one. We actually almost sued them but we were 3 years late to do that.
The GM 6.5 is still being made in Franklin, Ohio. It's now called "OPTIMIZER 6500" built by general engine products (GEP) owned by AM general used in HMMWVs and marine applications, both turbocharged and N/A
Toyota's L 2.2 liter and 2L 2.4 liter diesels did run forever, those were the most used engines in the 3th and 4th generation Hiace and also in the Hilux, I owned a 2.4l Hiace and just had to change the oil sometimes and fit a new oil filter, that's it. Worst diesel engine I owned was the Opel 1.6 liter diesel, fitted in a Kadett E Caravan, it was very slow, noisy and unreliable, a breakdown each month was guaranteed, so after 6 months I dumped this car at the first car seller i went past, accepting whatever bid he made for it.
Every diesel that have 3000 rpm max, big displacement and low power and torque, it can resist for long time with million miles......you can see the buses or truck expecially if they havent electronical element
The Audi 2.5 V6 TDI is not to be mistaken with the infinitely more reliable Audi 2.5 inline 5 TDI which was used in various Audi, VW and even Volvo cars. The 5 pot is a much better engine in ever way than the V6. Also, the Mitsubishi 4D56 is a bad engine. Numerous Series 4 Mitsubishi L200's come into the garage i work at, and they need a new engine block, because of poor quality metal used in the block. Therefore they get pitted in between the cylinders and cause head gasket failure in some cases, failing at anything from as little as 30,000 miles (still in warranty!). The Series 5 L200's use the 4D15 i believe, and so far are proving to be a good unit.
4D56 is a great motor, it has a fairly strong bottom end so I have no idea what you are saying here, yes the top end is known to not be as strong. But they are certainly not known for blowing head gaskets. They are known for pully failures which then get ignored. Ultimately a new head is needed (not cheap at $900+install) Also people skip maintaining the 4D56 which leads to premature failure. 4D56 is reliable and gets good MPG just very anemic.
How about BMW N47 (x20d) which had massive timing chain problems, further made worse that the timing end was at the back of the engine which makes it necessary to lift the engine when eventually replacing it.
so is it possible to convert the audi 6 cylinder with the vp44 to a traditional p pump swap used on the 5.9 cummins assuming you're using the same components? (assuming you could find a way to make the front cover work because the front cover that comes with the 5.9 p pump swap kits is for the 5.9 cummins) I know it sounds like a nightmare but do you think it is possible?
worst diesel ever made1978-85 GM 350 Old engine used in all gm cars, a modified gas engine, cracked cranks, broken oil pump drive, bad injector pumps, etc. Ford 6.0 first year 2003-4 is bad, rest are ok if unmodified.
My parents bought an oldsmobile cutlass in 1984 with the lf9 diesel engine. Had it until 1991 when my dad finally got tired of replacing headbolts for the third time and the fuel tank rusting from the inside out. I can remenber going to school, watching my mom start the car and having to rev it a little bit to keep it running until it warmed up, leaving black marks on the driveway. I was just a kid then, but I thought it was cool. Haha. But what i remember the most is it sitting parked because it was blown up or broke down for something else alot.
but in my country is problem with fuel with bio component, which destroyed these parts when I had the Peugeot 405 1.9 grd so these problems did not know and the consumption was 5 liters of diesel per 100km, and clean the EGR costs extra money + assembly and disassembly
The 20 largest ships in the world produce the same emissions as all passenger cars in the world, tell me about ecology, in Hamburg, it is estimated that cars are under a maximum of 10% of emissions in City. if it goes this way, then in the European Union, we will ride a bicycle or horse
Obsolesencization is a rumored tactic. I am watching two americans rebuild a standard transmission for an f-150 300. It is full of magic rings, patent number 5, 000, 000, 000, thereabouts, one is bad. The patent prevents you from harming the transmission if you jam the gear shift into reverse whilst preceeded hencely and, i presume, remove your foot from the clutch peddle.
Had a 2.5 TDI as my second car. got it at the beginning of my apprentice time at VW as a car mechanic. The first timing belt I ever did was on that monster. needless to say that as a rookie it took me about 13 hrs to get that thing changed. Luckily I never had issues with the bosh pump as the pre owner had it send to a spacialized diesel shop. At some point taxes got way to expensive so I sold it.
I would argue that its not so much the design of the engine in many of these cases, but that EGR was added to a diesel engine. EGR is pure engineering hypocrisy. It shouldn’t ever be used on a diesel engine. You gain absolutely nothing but a ticking time bomb of critical failure. Supposedly its put on there to cool down combustion to prevent NOx production and to give “unspent hydrocarbons” a chance to be burnt. But you wouldn’t have unspent hydrocarbons if your A/F ratio is greater than 18:1. And the best way to cool combustion is with cooler intake temps. But noooo the socialists f@&ks that make the regulations don’t want you to actually clean up your emissions in the way that will reduce fuel consumption and improve performance, that’s logical and logic just isn’t allowed in government regulations. Ok, I’m done ranting... but its your fault, you brought up EGR in a conversation about diesel reliability.
My 1980 Cutlass with a 5.7D engine runs just fine. As does my Datsun inline 6 diesel from the 70's. The Subarus has a problem with the double mass fly wheel. Often the sound is mistaken as an engine noise. The shop pull the engine and find no fault, then mysteriously after "rebuilding" the engine also find the flywheel problem. Selling it to the customer as the flywheel broke the engine.
meifert2 6.4 failures are a mix of poor early design of a scr mixed with top end that couldn’t not handle the high drive pressures of a compound vgt turbos. The engines do much better with a single fixed geometry turbo and deleted a tuned.
The 6.0 is fine if you know what you’re getting into and know how to bulletproof it. I own two. I got about 250,000 miles out of the bone stock Excursion I had. However, cold starts and blow by were issues by the time I sold it to a rebuilder. Which is where I purchased my second 6.0.
You can't make a good diesel that plays by *ALL* the rules. Power, Reliability, Efficiency, Emissions, and Weight. You have to sacrifice 2 to excel in 1. My personal favorite is a lightly modified 6BT. but I care about people, and I wouldn't do anything that worsens the NOX emissions.
Japanese can't make a good reliable diesel??? WRONG!!!!!! My dad has a 1999 Toyota Hilux with the 3L inline 4 diesel and it is currently at 350k km without any problems. My uncle has a 1993 Hilux with the same engine and it clocks over half a million kilometers and i haven't seen the first mayor issue with the engine, Oh and it drives like a champ
Those really aren't super high numbers for a reliable engine. Usually an engine isn't considered to be super reliable unless they go over 600,000 km regularly. The diesels in the Hilux, however, are usually the most reliable option as the gas powered V6's tend to be pretty crappy.
i know. The first gen v6 is a crappy engine: low power for the size and kinda unreliable. Second gen v6 is way better. I know that 500k doesn't sound like much but that was the last time i saw that mileage in the vehicle.... mi uncle daily drives the vehicle, maybe is reaching the 600k mark. i haven't been in the vehicle for a long time
First ever TDI engine was in Audi 100 C3 in 1989 and it was the 2.5 liter inline 5 turbo diesel, it was very reliable and legendary, but in Audi A6 b6 they made from a reliable and durable engine the unreliable 2.5 TDI V6. And I love old naturally aspirated American diesels
Oh yes I get it, I worked for Audi Sport as a mechanic nearly 1.5 years ago, the old Q7 with V12's were mighty cars and with the V8 too. I just left when the Downsizing started, the only car I drove with downsizing is the RS5..
GoldmineGaming damn that's cool dude 👍, it's true and sad about the engine downsizing 😔 and I'm kinda mad, well a lot mad to be honest, stupid ecologist vegan feminists
I once drove a Pug 309 D, with the 1.9 NON-turbo diesel engine. My god, i could have got out and walked faster. Pulling out of junctions was scary as you needed a 0.5 mile gap in traffic to get going.
early 5.7 diesels used a standard 350 rocket block and were essentially a gas motor that was converted to run on diesel, later versions used a heavy duty diesel "dx" block that can actually be converted to run on gas. both engines had major reliability problems as well as pathetic power output
At that time, they were the fastest diesels around 160-170 kph and the most powerful... All other diesels till the late seventies had around 40 to 85hp. High end cars like the Mercedes 300 SD had a straight 6, 3.0l Turbodiesel and 125 hp but most were n/a. So yeah... olds and caddys were heavy oil powered rocketships !!!
My 2016 Merc with the 2.2, and a Brabus D2 tuning kit has 215bhp, and 420NM. And still does 68mpg on the motorway. The OM651 is the best diesel engine of this century.
My Dad had the '79 Olds Cutlass 4 door. It came with the 260cu/in engine that put out around 80hp and was a real dog-actually dangerous to drive. Then at about 50,000 miles a hose blew when my Mom was driving it and she said it lost power and just stopped-froze solid. So we had a 350cu/in installed and with the increase in power (120hp) we discovered the little turbo 200 automatic transmission was slipping. We found out that the turbo 350 automatic would bolt up, and then had a great transmission. The 350cu/in lasted about 30,000 miles, then had a cylinder crack with water leaking into the cylinder. Basically had a long block installed. When it ran, it ran well. But the last straw was once again (third time) the fuel injection pump failing. I didn't want to pay the $800 plus labor to repair it, so I paid $250 to have it hauled away. Was ashamed since it was a nice car to drive and except for the engine, was reliable.
I’m surprised that the 6.0 Powerstroke was on here instead of the 6.4 Powerstroke. Usually on a 6.0, you could replace the studs, replace the egr cooler, and make sure you push it every once in a while to clean it up. The 6.4 just had so many problems that you couldn’t fix one thing without worrying about another.
What? Toyota's D4-D are pretty good engines. 2.5 TDI isn't so bad, in fact they're much better than 2.0 TDI which are just shitty. Also, one of the worst diesel engines are Inline-4 BMW M47.
@@toomanybears_ Ha ha ha! And still they are so stupidly huge. Waste of money and time. The old ones before the ECU age at least made sense. Endless money pits for trucks that do what a Honda can do. Go from A to B XD Get a real truck with 12-18 gears and 1L+ in every cylinder. If not for 4WD the big rigs got every advantage and much cooler. 13L V8 730Hp. Factory EU truck. Or why not 24L v12 2000Hp from factory :) Only wheel friction and money being a problem. You just tip the cabin to acess the engine in a EU tuck :) Remove the front wheels for better access.
@@TheDiner50 I got a 3500 dually to pull a large horse trailer, ~20k lbs fully loaded. You're not going to pull that with a Honda Civic. And it fits in my garage, pretty sure a semi tractor would not do that. I really did NOT want a 4 wheel drive but that's really all that's out there and it has come in handy a couple of times, we get some pretty heavy snows here on occasion.
The Detroit 6.2 and 6.5s weren't bad engines. The only real problematic parts in those engines were the horribly unreliable stock injection pumps, and on later 6.5s a badly placed controller that would overheat. Both aren't too hard to fix. Yes, they don't make much power, but they will last an extremely long time if cared for correctly.
Despite the 6.0L's reputation and its known flaws, it has been around long enough that you can bulletproof them well. Plus, any early 00's truck is going to be of the age and miles that it will probably be time for a refresh anyways, so that's when you do the work to the EGR, oil cooler, HPOP, heads and such. Not necessarily delete the smog devices outright, but replace them with better components and procedures. Lack of a DPF makes this relatively (kinda) simple and they can be reliable once the engine is done up right. Now, the real turkey was the 6.4L as it was the first Powerstroke that had to meet the more modern emissions requirements. Add to the fact it was scrapped after only 2 years and you have an engine that is unreliable AND has a short production run, but also has far less support and creative solutions built to solve those issues for second and third-hand buyers.
Yes! We moved from a 1.5dci Nissan Juke (horrible car I know, it was the SO s car), we moved to a 2015 Mazda3 2.2, what. An. Engine, there is minimal lag at all RPMs and no perceivable boost threshold. Plus, 70mpg(UK) on the motor way @ 70-80mph. The Juke wouldn’t even manage 50mpg at 60mph! The 1.5dci had a plague of problems.
mulymule12 also this engine works without adblue and the maintenance is cheap in comparisson with other diesels. In my case i bought the 2.0 165hp instead of 2.2
Personally i prefer the Merc 2.2 diesel. Smooth and very refined. Power ranges from 136bhp to 205bhp depending on spec. The OM651, still used in almost all Merc ranges today. So good that Nissan are now using the Merc engine in the Infiniti Q30.
I love the 6.5, move the pcm and the fuse block, update the injector pump, and its practically bulletproof. The cranks are known for snapping cause of faulty balancers and bad metal batches, but that fix is a 6.2 bottom end with a 6.5 top end. They are not a 12v in terms of speed or a 7.3 in terms of factory strength out the gate, but itll get you, what your towing, and anything else there happily and with decent mileage. Dont forget the 6.5 lives in a fuck ton of Humves.
My parents had both 6.5 (and still has today) and 6.2 suburbans late 80's I liked the 6.2 simple and less shit to break on a family hauler of 1986 suburban unfortunately he sold that one and i ended up buying a 94 with the gas 5.7tbi for my family nice burb a bit thirsty but i would choose iron blocks over this aluminum shit sold nowadays
The 'problems' with the 5.7 and 6.2 GM Diesels can be easily remedied. ARP studs and a fuel/water separator vastly improves reliability for both engines. The 6.2 took off from where the 5.7 Olds left off, still utilizing a Stanadyne mechanical fuel pump best suited for tractors, but does alright for automotive if you take care of it. Boost a 6.2 with a turbo for more power, just make sure to build up the top end with high compression copper gaskets, and replace the head bolts with hardened studs, and add a block girdle to add some block strength.
I'm gonna have to go against the 6.2 detroit diesel being unreliable. My dad still has one in a 1983 van and it has now done over 800k miles and we have not cracked open the block once. Only regular filter changes and fresh oil will keep it running forever. If anything the body will rot away way before the engine dies :D If you want to talk about unreliable diesel engines, we can talk about the 5.7l Oldsmobile V8 diesel, now that is a crappy engine.
JackPecker911 I agree with you. I own a 1995 K3500 Dually with the 6.5 turbo which I beat the hell out of as a work truck, and it never wanted to stop. This guy said don’t “overload them” I towed over 15,000 LBS in that truck through the mountains with no trouble. I also own a Civilian Blazer with a 6.2 Detroit from the factory, it’s a 1984 model. The truck has 385,000 on it and still going strong. They’re good motors, they can pull well ( a little slow off the start but can get up to speed ) they’re reliable, and they make great fuel mileage. They were also the first diesel out of Ford/Chevy/Dodge. Chevy in 1978, Ford in 1983 Dodge in 1989. Detroit is an all around good diesel and apparently this guy has no idea what he’s talking about because they’re great motors.
If I swap in a crate 6.2 will that solve any issues? It’s a brand new turn key motor and I see a decent m1009 blazer near me
i agree 100% we have a 1982 and it will NOT DIE never will. never had a better truck ever.

Isuzu diesels are perfect
Antonio. Toyota engines are also very good
I have an 82 Isuzu I-Mark diesel, 1.8L 4FB1. Slow as crap but reliable as hell.
Or Kubota Mitsubishi Yanmar Isuzu
The 6.2 Detroit Diesel engine is far from a bad engine. They are a lower performance Diesel engine but they are extremely reliable as long as you take care of them. It’s not a 5.9 Cummins, you can’t beat the living hell out of it it’s whole life and run it a gallon low on oil forever and expect it to last. But it’s not bad. They are a cheaper priced Diesel engine because of the lack in power and the fact that most of them sit in the old 80’s Chevy square bodies that are almost always rusted out. But I can say from experience that although your not gonna be winning any drag races anytime soon you will have a decently efficient and reliable power plant.
Collier 620 I want a square body, but they're do expensive compared to 12v cummins. That and I do want a crew cab, so that's probably also why they're so expensive. I was trying to find a cheap and reliable diesel truck.
Collier 620 6.2l and mercedes 2.0l diesel are engines that i like! they are not fast or powerfull but they will run and run and.......
better off Frankensteining something with current prices
Jürgen Von Parsberg 12v Cummins is a true diehard. It’ll outlast anything else out there. I love the 6.2 but it’s just not a 12v. There simple, reliable, and if you can afford one with a 5 speed, go for it. It won’t let you down as long as the trans hasn’t been abused badly, stay away from ones with automatics tho. That trans was way under spec for the torque of the Cummins. And yeah, the crew can square bodies are getting hard to find especially if you don’t want a dually. Personally out here in Kansas I’m looking for a good 12v truck but the cheapest ones are rust buckets that people want $5,000 for. I’d love to get an 80s suburban with a 6.2 and daily it
JBat5202 true there. I’m kind of doing that anyways, looking for an old 6v92 or 71 Detroit to put into something just for the hell of it. That’s gonna be a long project but it should be fun
The Isuzu 2.2 liter was one of the best Diesel engines Japan has ever made. Japan rocks the light duty and medium duty truck market with the Isuzu built Duramax diesel line up.
Japanese can build proper diesel engines, and they are already doing it since the 70's.
Toyota, Isuzu and Mitsubishi all used to make great diesel engines that are still going strong to this day. The problem with new diesels isnt exclusive to the japanese.
nowadays toyota 2.0 D4D engine is pretty reliable even with DPF and EGR
Yanmar makes a great diesel engine mostly marine but will show up in tractors too.
@meteorbdragon100 yes man I am from Indonesia I have 1991 Isuzu panther with isuzu c223 engine non turbo diesel it is very slow but very reliable it has 762.000km and it's still going fine with no engine problems
Amen. The toyota landcruiser engines are the best diesels ever made and the Isuzu’s are bloody amazing as well

I am only 15 and I bought it at 14 when I got my farm permit and I have already put 30,000 miles on it. That truck has been a real workhorse for me.
6.5L V8 turbodiesel...
Don't tow heavy things, not meant to do that... IT'S A TRUCK ?! WHAT ARE THEY GOOD FOR
I was confused by that too, a diesel powered pickup truck is literally made to tow stuff. It's the reason you'd buy one :D
I was puzzled by that statement too, because if that's the case there's not much point buying one!
IDK. Uncle had a 6.5 turbo towed everything he wanted to pull. Cuz had a 6.2 in an old suburban years ago. Slow as all hell. But got 20-23mpg towing a ski boat. That's no bad.
A big truck wich cannot tow heavy things? Wow, That's what i call shameful.
Never had a problem with ours we used to haul the backhoes with it for my uncle
Most of these engines are great, it's just the stupid "emissions" systems that fail or ruin them.
Injectors and high pressure pumps aren't "emissions" items.
Yes, blowing head gaskets are because of emissions

I suppose you're opposed to sewage treatment? Just dump the sewage in the river. Your water-sewer bill would be less
I've got a legacy diesel and it's brilliant - bought it off the back of a load of customer reviews. Only downside is expensive parts. Never had any problems
This entire movie was discredited by the fact that the 6.2 and 6.5 Detroit for General Motors line of trucks made this list. While not power houses they're reliable. But the movie got one thing right here. They get really good fuel/oil mileage. Notice I said fuel meaning diesel and then oil or waste motor oil. They weren't very picky about what they ate so long as you didn't expect them to eat water,gasoline or alcohol. They would run good on waste oil so long as you filter it beforehand. And as a farm boy and exfarm hand I learned that was extremely handy. So long as you maintained them properly they keep going. As a matter of fact I know most of them in my small hometown are still doing the same job that they were when I was a teenager. It is 2018 I'm 32 now and at least two of them are older than I am. There just a little Rusty'er from the last time I was in them. Haha
Reliable? LMFAO!
Brentelec I had a 6.5 in my 1995 K3500 dually. Say what you want but I beat the shit out of that motor as a work truck and it just kept going nonstop.

i had a blazer that went through three 6.2s each with well under 100,000 miles on them.
The 6.2 Chevy diesel is one of the best motors ever made, it is durable as hell! The 5.7 DX diesel will keep on running if you drive it in the right way and maintain it!
That's funny....its a POS. Buy a 350 small block and save yourself some trouble. At least GM got that right
Back in the day my neighbor bought one of those GM diesels and lived to regret it. As far as the Ford Powerstroke goes, most buyers rued the day Ford retired the half-million-mile International 7.3 for the new PoS!
Two examples of a good diesel, Fiat's JTD, used in the Tempra, and believe it or not, the Austin-Rover/Perkins L-Series Prima turbo diesel, as used in Monetgo/Maestro and beyond. Both were powerful direct injection turbo diesels at 2 litre. The Perkins/Rover unit was especially solid.
The Rover L-Series is an absolute cockroach of an engine. I saw one at a show a couple years ago with 1.3 million miles on the clock! Great unit.
“The Japanese just can’t make a reliable diesel engine”... hold on there sunny! Isuzu is Japanese and they are arguably the worlds best diesel engines. Nissan is also an excellent engine manufacturer. Fuji Heavy Industry (the parent company of Subaru) makes many high quality diesel engines. Mitsubishi is another excellent diesel engine manufacturer.
I think you’re smoking a bit too much hash with your statement.
The new Nissan Titan diesel uses a turbo Cummins V8.
You forgot about Mazda diesel engines used in older Ford Escort Diesel cars. They were only made every 4 years.
@@buddyclem7328 I know.. put 200000 miles in my escort 1.8d never missed a beat

The 6.2 is actually a good reliable engine
On the LF9 GM diesel, where i grew up they converted them to gas and made drag racers out of them. They were great, since you almost couldn't kill them with power. I lived in Michigan, where most of the car disappeared after a few seasons, so getting them cheap was not a problem
I have to disagree with the Japanese diesel engine part, especially Toyota because one of their diesels, the KD series used in Hilux and Hiace (and in a certain compact MPV sold in Southeast Asia and parts of the UAE), has a rock solid reliability. Isuzu also made extremely reliable diesel engines, some of which can run well past a million kilometers without much trouble.
Yea. Here in finland there was news article about KD series. They dont anymore take engines of from crashed cars because ten year old ones are still in the storage collecting dust :D
didyliduu I'd assume those engines are still in working order despite collecting some dust.
But it had SO LOW power and torque, Any medium NA diesels with no EGR lives forever but they were so underpowered because emissions
ScoutSpyScout gotta agree with that. The standard 2.5 liter 2KD only made 100 hp and 147 foot pounds (non-intercooled turbo ones with manual, automatics have slightly higher torque at 191 foot pounds) with its latest iterations with VGT topping out at 142 hp.
Mitsubishi make some good diesels as well!
Another worst Diesel-engine ever is made by a japanese-american company: Isuzu.
The internal called "6DE1" or "DMAX V6" engine was used in Opel/Vauxhall Vectra C, Signum, Saab 9-5 and Renault VelSatis and Espace. Only a few of those engines passed 100.000km/60.000miles without a broken engine or broken diesel pump. The liners were likely to slip down. Exhaust gases are pushed into the cooling system then. The engine runs hot. Some mechanics diagnoses that the head gasket is blown. But in 99% the liners are broken. The Denso high-pressure diesel pump does not like biodiesel. The valves break down. You should fill up premium diesel (without biodiesel) only OR with normal diesel you should put a bit of 2-stroke-oil in the tank every time you need to fill it up.
Isuzu don't make a bad diesel engine.. The mileages the old 4JA1 and 4JB1T (to name a few) can do are testament to that.. There is one in South Africa that has done over 1 million KM's- verified.
Matthew Shambler Agree mate, Isuzu's diesels is badass, very reliable, cheap to repair...
Leonard Carr , Lol.. yep, good old Isuzu Bakkies- AKA pickup trucks for the rest of the world;-)
here in Indonesia the 4JA1 is glorified much, it's on par with Toyota Hilux kind of reliability
Matthew Shambler , isuzu p9x very bad diesel
O yes, you have to put some miles on to wear through the hard chrome on the liners.
The 4JB1T survived the lack of an intercooler well.
They would boil the coolant and burst pipes long before the high egt's could think of cracking a head or melting a piston.
I would get overtaken by a 4JB1T with a caravan behind it on the way back to Johannesburg from Polokwane whilst I had a 4JA1 doing the speed limit at full power.
An hour later I would pass them stranded as they had blown the cooling system and it steamed like a volcano next to the motorway.
But that motor shredded the tranny if not driven responsibly.
Have a lot of respect for that motor.
The sub is still in production, they have efi fuel injection now and I presume some head changes (Have not researched)
GM have refined a timeless classic.
I’m going to disagree with the 6.2 and 6.5. I’ve had a 6.5 in the past. Like you said, it’s an economy diesel with torque and horsepower coming in at low rpm. It’s not that they can’t tow, it’s that they can’t tow where you’re showering down on them. Their peek efficiency is around 1800rpm. As far as their problems, the marine industry has the solutions for most of them because of their popularity for ship generators, not to mention their military applications.
My dad has a land cruiser 3.0 D4-D and it runs perfectly after 15 years.
Our Hi Ace D4D 3ltr diesel, over a million kms trouble free, only ever injector serviced once and the inlet manifold cleaned out once, damn good reliable strong engine!!!!
OK tell me, what's considered a heavy load for a 6.5l turbo? I pull a trailer of between 1 1/2 and 2 tons with mine and no problems.
Own diesels of the Honda are not bad at all. And mind you, the Japanese have been making diesels not just for passenger cars but for light and heavy utility vehicles as well. And they are excellent in their own manner.
I'm honored my 6.5 Chevy Turbo Diesel made the list. The main problem is the PCM change that at some pointe. my truck is a chip box easy dump with a chipper towing Alway 10000 plus pounds.
Actually, I've had very good service from the GM diesels I've owned.

Yep, my band's first van was a Ford with the 6.0 diesel. 2004 with 120k miles, bought in 2012.
Problems we had: EGR valve failure, alternator failure which killed the FICM as well, significant fuel leak in two places, and finally, EGR cooler failure which put coolant through the motor.
Engine is near impossible to work on in a van... 0/10 would not do again.
im super stoked that one of my videos made it hear hahaha
So what's the problem with the 6.5?
Japanese can't make propper diesel enigines? Apart from the one you mentioned all of the big diesels in the Toyota Land Cruisers for example are great and some of the most reliable engines in the world when maintained propperly. With a bit of care the 6 Cylinder-Diesel Engines like the 1HD-T, 1HD-FT or the 1HD-FTE run for litteraly millions of kilometres.
The 2AD its like the black sheep talking about toyota diesel engines. Most of them are so reliable.

While being inexperienced and feeling invincible, I bought a 6.0, feeling like I could tackle everything it threw at me- The head bolts did not fail, I ended up deleting the EGR cooler, installing a fuel pressure regulator spring, replacing an icp (injector control pressure) sensor, installing stainless steel up pipes, and a turbo back 4" exhaust as well as an SCT livewire ts+ tuner running on the lowest (50 hp) tune that I still have problems- I never beat it up or run the rpms to redline, my heads are still fully intact, i'm not using up coolant, I have an injector going bad which i believe is the o rings on the injector as my start up and warm up exhaust is blue and I have a rough idle/ miss at times which follows the injector solenoid failing issue which in whole contributes to the amount of oil i/m using/ burning; I asked my co workers about this (who have 40 yrs experience in the field) and agreed with my diagnosis. Also, I have an oil leak which I believe (just looking up with a flashlight) is coming from my icp sensor again, a year later after replacing the old one which ended up being an o ring, I believe this one is either an o ring or the whole harness, regardless, i'll replace both. but the moral of the story is it depends on which 6.0 ya get- mine also has steering arm, tire rod, control arm bushings that are completely shot and haven't seen grease in years. The front end needs some work :) The Minnesota rust doesn't help.
Bet that piece of shit broke down soon after that post 4 years ago
tbh id still rock a olds diesel wagon
I have an 82 Caprice diesel wagon! LOVE IT!
@@jolo4036 It's amazing that some of these diesels survive. This means they are not all bad.
a few mods can easily boost the reliability and then power of the Powerstroke 6.0's, but from stock, they are lacking. they do sound REALLY good too: the 6.0 is the diesel that made me interested in diesel performance in the first place
my uncle had a 6.2 n/a, and though it was a sloth, it got 24 mpg on the highway with a trailer and a racecar inside it from the factory. no clue on how much the setup weighed, but it was reliable for quite a long time. he was astonished at the mpg it got but hated being stuck in the slow lane so he got a gas engine when the 6.2 needed servicing.
the military has used 6.2 diesels for decades, and they are very reliable now, but thankfully, are being phased out for a much more powerful and capable Duramax engine.
"The LF9 wasn't a Rocket 350 turned into a diesel as many think, but some components were shared."
Self contradictory statement. The reason the engines shared components was because that's exactly what GM tried to do - to make a diesel engine out of an existing gasoline engine design instead of starting from scratch like they should have. They did it because for a brief while diesel was significantly cheaper than gasoline, and GM was rushing to put something in production quickly.
They shared a few parts with the gasoline V8, water pump, valve covers, rocker arms and bridges, oil fill tube, rod bearings, exhaust manifolds and certain oil pans.
Blocks are different and use the big block 3" main bearing crank journals, other parts unique to the diesels: heads, connecting rods, pistons, camshaft, lifters, pushrods, intake manifold, timing gears, lift pump, flex plate, starter, oil pump drive/vacuum pump.
The Ford-PSA designed 1.6L turbodiesel. It's called DLD-416 or DV6 and it's found in: Peugeot, Citroen, Ford, Volvo, Mini and Suzuki.
The mode of failure is wear and tear: the oil pan design is poor and all the oil doesn't drain properly. As a result you have malfunctioning EGR, DPF fills up sooner than expected, valves get badly carbonized, turbo gets seized and overall the engine is just clogged with black burnt residue.
If you have to buy one, get a low mileage one, double the oil change intervals, take the oil pan out sometimes (not just the plug) for complete cleaning and redline it properly once a day.
I love my 6.5 diesel it’s cheap af for parts and is like working on a 350sbc. I have a bigger turbo and it’s tuned. Makes good power for now 300k and counting
Is Audi l5 2.5tdi motor is good? The one that goes into 2000ish Volvo V70?
The 6.0 and 6.4 powerstrokes aren't bad engines per say but they were meant for schoolbusses and it was made by international instead of ford, the new 6.7 is made by ford and it is way better stock, and if you bypass the EGR on the 6.0, change the head gaskets and studs and o-ring the heads it's pretty reliable, the same procedure applies to the 6.4 but with another step and that is to delete the DPF, It's a shame the V6 tdi is a bad engine it sounds amazing and if we wouldn't get shafted here in sweden on taxes i would've gotten one
In USA some pending state legislation will make it a big monetary fine if you delete air pollution controls and your caught. Some state do check for them and if missing wont pass inspection
In regards to the VW Group's 2.5 V6 TDi, the original 150HP is the really problematic one and even then, it mostly applies to first years of production, which are also the engines with most fuel pump and turbo issues as well - or rather, were the ones, since most of them either died or had the problematic parts replaced. After that, the engines got considerably better in regards to reliability, although they still require considerable care. I have the AKE (132kW/180HP) in my car, changing oil every 7.5-10k kilometers (4.7-6.2k miles approximately, I think), not being cheap with the consumable parts (filters, timing belts, etc) and buying decent quality fuel, and I never had any real issues with the engine - approx. 370k km (230k miles) and some of it with short distances which is far from perfect for a relatively large turbodiesel (for european car).
BAD LUCK BRIAN: *Buys a VAG diesel car, it’s a 2.5 V6 TDI*
Some versions of 2.0 TDI were also horrible.
1.9 TDi also sucks.
1500 euro repairs ona 5000 euro car
Bullshit, the 1.9 TDI engines made before mid-2000 are bulletproof. For example the ALH 1.9TDI, found in Audi A3, Bora and Skoda Octavia MK1 is capable of running 600 000-700 000km without a major rebuild, excluding clutch and timing belt changes but those have to be changed anyway at some point.
1.9TDi usually is one of the best small diesels. 2.0 and 2.5tdi's are horrible engines. of course every engine has its flaws
haha, sure.
2007 Touran 1.9 TDI 105 at 140 000km it had to have its turbine, actuator, flywheel and clutch replaced.
Plus it's a BXE which means it could put a rod through the block at anytime.
Not a big fan of v6 engines especially diesels they always have a rotten rattling sound but the 2.5tdi was a very good engine to me tbh. Sure I needed it cleaned up occasionally but I loved it!
WHAT!? Japanese can not make good Diesels? As a Renault owner you have to know that the 2.0 dCi in the Megane, Laguna ect. were troublefree and goodrunning Renault-Nissan-Diesels!
ElectronicRedPanda
They are all good and reliable and silent. Of course there are some that break down but 80% are good.
The new Dci engines are much more reliable and they are developed by Renault and Nissan.
Sorry to burst your bubble about Renault- Nissan diesels, they were Renault designed and built engines that are great, Nissans own engines as fitted to the Pathfinder and Navara ect. are absolute Shit. Nissan diesels used to be great but not the newer ones with their timing chain snapping issues and oil leaks. I had a Nissan X-Trail 2-2 dci Aventura which as absolute crap, Nissans aren't what they used to be in the past, some people blame Renault for this but it wasn't the Renault engines that failed, the Clio 1-9 diesel I had in 1994 was one of the best diesel cars I've ever owned, fast and frugal it was great and did over 120,000 miles before I sold it.
As a prior owner of a high-mileage 6.5, I can tell you that they aren't bad engines, depending on what you need one for. They are meant for light towing/fuel economy at heart, not heavy towing. The 6.5 is bad about snapping the crankshaft under heavy load, and the 1995+ 6.5's are bad about the PMD going out. (pre-1995 engines do not have electronic fuel injection and are far more reliable.) If you keep these things in mind, and use it as it was designed, the 6.2/6.5's are very good engines. There's a reason the government used them for many years, including in the humvee's.
I must admit, that this VAG 2.5 V6 TDI is really unreliable, but damn, those engine sounds are like a piece of art! I used to have some experience with BAU coded engine (which supposed to have those camshaft and rocker problems removed). Those sounds were stunning, apart from knocking noise 60k km after :D
sad I have only driving the 5 cyclinder one
The GM 6.2/6.5 was not a bad engine, its weakness ( I ended up finding out from specialist Heath Diesel ) was the coolant system. The coolant distribution from the right side of the block to the left was imbalanced causing head gasket issues. I owned a 6.2 and it did the job.
I liked mine . It was definitely a dog though compared to a newer direct injection diesel. I actually replaced my 6.5 with a 6.2 block . It ran great with awesome fuel mileage.
Maxxforce 13 should have been at the top of the list
We had a 6.5 turbo on a work truck and we flogged the hell out of it. Of course we had to replace pumps almost yearly but we frequently pulled 20k lbs with it and although it wasn't a fast truck, it got the steel where it needed to be.
How did it make it to almost 150k miles? We were very meticulous about maintenance because the trailer was almost never unhooked and it was loaded to capacity or the truck idled waiting to be loaded. There really was no in between for that poor rig.
Nissan Renault yd25 and yd22 are well know for the bottom end failure, conrods snapping, blown head gaskets, timing chains, cracked heads, and more,
Some of the engines I can think about:
-1.9 Dci 120hp from Renault Laguna II
-2.5 CRD from Jeep Cherokee ( each cylinder got it's own head and is prone to leaks )
-1.2 & 1.4 TDI - crankcase goes loose after about 150000 kms
-2.5 TDI V6 - not to be confused with earlier 2.5 TDI inline diesel, which is good
-early 1.5 Dci - when oil was changed with intervals taken from manual ( every 30000 kms ) the whole engine and especially crankcase could be destroyed quickly
-2.0 TDI PD - head, head gaskets, pistons and oil pump failures. Not to be confused with later 2.0 TDI CR
-not exactly bad, but engineered to make owner pay more - BMW N47 diesel, with cam belt going loose quickly, accompanied by its placement near gearbox, necessitating in removing engine from the car
About Japanese diesels - in fact I would say that most of them are good and some are very good:
-2.2 CTDI from Honda Civic and Accord - no major problems
-1.4 D-4D from Toyota - may suffer from DPF failures, but far less than other modern diesels ( additional injector in the filter )
-2.0 Dci from Nissan - used by Renault in Laguna III and such, no major problems
-old non turbo 2.0D from Toyota and Nissan - slow, noisy but reliable - they are workhorses
-1.8 DiD from Mitsubishi - no major problems
2AD loves blowing head gaskets, not Toyota's finest moment.
D C similar to the petrol 1 and 2 as units 🤦♂️
Az*
That depends which 2AD, the 177bhp version in the Toyota can be unreliable mainly due to head gaskets and DPFs however the 120 and 150 2AD FTV versions which don't have a DPF are reliable in my experience.
My dad have a 173hp (130kW) 2AD Avensis from 2008. With it chipt it has 200hp (150kW). He works most of the time and maxes out his overtime every month. He works at a place 50km from where he lives and have had NOT a single problem with that engine. He did destory a brake disc and brake pads in the back from ice build up. Had some normal wear like wheel bearings and stabilization arms. Like the worst thing to brake on it was headlight bulbs.... Pure pain to change them out :c
Fule usage. 6.4L / 100km if you drive around 80-90km/h and is nice to it. But dad is not nice to it and likes to pull ahead of BWM drivers at stops lights that think they are something :/ (and also drives at 130-150km/h....) He average 7.1L / 100km. Calling it a bad diesel is just wrong... It is not thirsty fools. It is just a big heavy modern car. Mabye they have gotten worse? Anyways dads Avensis I have respect for. Very few modern cars I can say that to.
100km 5 days a week for 8 years now. In -39 Celsius to +32 snow, rain and mud.
Before he own it it was a leasing car and had a ruff life with scraped rims and the gearbox was like if someone that did not know how to drive a manual had it before him. (first and second gear was a mess) but still works 8years later. Just have to be careful when it is cold outside. It as many miles on it. We are talking about 300,000km at least. I don't know for sure but due to it being diesel it will just keep running until old age catch up to it. That being soon :c
it was not only the gasket, it was the blown Head oder Cylinder block! but at all a very bad engine!
Had experiences for quite long time with an Oldsmobile (Custom Cruiser) 5.7 Litre V8 Diesel. It's confusing. Ours has never failed while it was in the family. With the original 3-speed Hydramatic transmission it worked comfortably till 90-100 Km/h. Some friends of ours owned few other 5.7 Litre GM diesels and most of those engines had failed. Options to keep them on the road as long as possible was/is the transmission replacement for a 4-speed automatic. As well as the engine replacement for the mentioned 6.2 and/or 6.5 Litre V8 diesels which were more reliable. With these modifications the top-speed could be increased safely till 130-140 Km/h. All in all 5.7 D was a weak engine and the only goal of it was the low fuel consumption for its size. The best and lowest average we had reached with it was astonishingly low. 8 litres per 100km.
The 6.5L and 6.2L Detroit Diesels should not be on this list... These engines have a reputation in the motor boat industry that is like the 5.9 Cummins in the Pickup trucks... They have been the only engines ever used in the US Military HMMVEEs and get any where from 21.5-29MPG.... The only problem with these engines is the way GM installed them in the vehicles, the accessories on the serpentine belt and the fuel systems are the problem, not the engine it's self... 6.5L and 6.2L never had their "common problems in the non-civilian road vehicles they were installed in.
Yes, they were in HMMVEEs - but they had the budget for them. Unless you inherit the US Treasury, avoid 'em.
@Corn Fed Owned a 6.5 (1999, last year for civilian models) for almost 4 years, never had that problem but I've only put about 25k on it. Glow Plugs are old, though.
humvees had a reputation for blowing up engines
The Olds 350 was not a 350 converted. It was a purpose built engine using existing tooling to help save on costs.
A 6.0 is a damn good engine if done right. All problem stem from egr problems delete all the emissions they will run for forever
Ty Bailey We love ours. Kinda pissed at Ford though for replacing the same faulty part in instead of a new one. We actually almost sued them but we were 3 years late to do that.
What about when it's illegal to do so?
Reid Johns aftermarket is great for these truck though turn them into real bad ass machines
Ty Bailey We wanted to do stuff like that but we couldn't really afford to, and were also trying to use up the warranties from the replaced parts.
The 6.4 is the bad one
The GM 6.5 is still being made in Franklin, Ohio. It's now called "OPTIMIZER 6500" built by general engine products (GEP) owned by AM general used in HMMWVs and marine applications, both turbocharged and N/A
Toyota's L 2.2 liter and 2L 2.4 liter diesels did run forever, those were the most used engines in the 3th and 4th generation Hiace and also in the Hilux, I owned a 2.4l Hiace and just had to change the oil sometimes and fit a new oil filter, that's it.
Worst diesel engine I owned was the Opel 1.6 liter diesel, fitted in a Kadett E Caravan, it was very slow, noisy and unreliable, a breakdown each month was guaranteed, so after 6 months I dumped this car at the first car seller i went past, accepting whatever bid he made for it.
dieselmupke always late in a 2.8 but always there
dieselmupke I have 2.2 diesel 177hp in my RAV 4 , its a tank
Jovan Karavezic yeah no its not
Hilux engine is very very durable. I have the 2015 model and I only go to the mechanic to change brake disks and stuff like that.
Speaking from my own experience , regular services and no problems :) Pulls uphills like there arent any
Every diesel that have 3000 rpm max, big displacement and low power and torque, it can resist for long time with million miles......you can see the buses or truck expecially if they havent electronical element
The Audi 2.5 V6 TDI is not to be mistaken with the infinitely more reliable Audi 2.5 inline 5 TDI which was used in various Audi, VW and even Volvo cars. The 5 pot is a much better engine in ever way than the V6.
Also, the Mitsubishi 4D56 is a bad engine. Numerous Series 4 Mitsubishi L200's come into the garage i work at, and they need a new engine block, because of poor quality metal used in the block. Therefore they get pitted in between the cylinders and cause head gasket failure in some cases, failing at anything from as little as 30,000 miles (still in warranty!).
The Series 5 L200's use the 4D15 i believe, and so far are proving to be a good unit.
Inline always is better than V...
4D56 is a great motor, it has a fairly strong bottom end so I have no idea what you are saying here, yes the top end is known to not be as strong. But they are certainly not known for blowing head gaskets. They are known for pully failures which then get ignored. Ultimately a new head is needed (not cheap at $900+install)
Also people skip maintaining the 4D56 which leads to premature failure.
4D56 is reliable and gets good MPG just very anemic.
How about BMW N47 (x20d) which had massive timing chain problems, further made worse that the timing end was at the back of the engine which makes it necessary to lift the engine when eventually replacing it.
leave my 6.2 alone she works hard and gets good mpg
so is it possible to convert the audi 6 cylinder with the vp44 to a traditional p pump swap used on the 5.9 cummins assuming you're using the same components? (assuming you could find a way to make the front cover work because the front cover that comes with the 5.9 p pump swap kits is for the 5.9 cummins) I know it sounds like a nightmare but do you think it is possible?
Renault 1.9dci 120 hp is a magic engine... Black magic;-)
Luca Brecel Ask sb about his cousin 1.5 dCi 😉
This type of magic throws rods straight trought block
First K9K engines were nightmares...
Also compression ring gaps close causing the piston failures. Fuel pumps are rubbish aswell :D
2.2 dci from gen. 2 laguna turbo and fuel nozzles fail till 50 000 km (allmost new engine)
can you swap the broken things and replace them with sturdier things? sorry for my typo's
worst diesel ever made1978-85 GM 350 Old engine used in all gm cars, a modified gas engine, cracked cranks, broken oil pump drive, bad injector pumps, etc. Ford 6.0 first year 2003-4 is bad, rest are ok if unmodified.
Couldn't have said it better.
My parents bought an oldsmobile cutlass in 1984 with the lf9 diesel engine. Had it until 1991 when my dad finally got tired of replacing headbolts for the third time and the fuel tank rusting from the inside out. I can remenber going to school, watching my mom start the car and having to rev it a little bit to keep it running until it warmed up, leaving black marks on the driveway. I was just a kid then, but I thought it was cool. Haha. But what i remember the most is it sitting parked because it was blown up or broke down for something else alot.
Why did your dad keep replacing the same headbolts? All he had to do was change them out and it would have been much more reliable..
He could have used the stronger headbolts. Maybe he would have held on to it longer...
Mostly engine here is good, but eco shit things like EGR and other slowly destroyed engine.
but in my country is problem with fuel with bio component, which destroyed these parts when I had the Peugeot 405 1.9 grd so these problems did not know and the consumption was 5 liters of diesel per 100km, and clean the EGR costs extra money + assembly and disassembly
The 20 largest ships in the world produce the same emissions as all passenger cars in the world, tell me about ecology, in Hamburg, it is estimated that cars are under a maximum of 10% of emissions in City. if it goes this way, then in the European Union, we will ride a bicycle or horse
Obsolesencization is a rumored tactic. I am watching two americans rebuild a standard transmission for an f-150 300. It is full of magic rings, patent number 5, 000, 000, 000, thereabouts, one is bad. The patent prevents you from harming the transmission if you jam the gear shift into reverse whilst preceeded hencely and, i presume, remove your foot from the clutch peddle.
@ElectronicRedPanda No, IF you delete egr on most engines you gain like 3-5mpg
Just like the semi’s emissions are killing that industry the engines are not reliable anymore the crapar I mean paccar is the worst
Had a 2.5 TDI as my second car. got it at the beginning of my apprentice time at VW as a car mechanic. The first timing belt I ever did was on that monster. needless to say that as a rookie it took me about 13 hrs to get that thing changed. Luckily I never had issues with the bosh pump as the pre owner had it send to a spacialized diesel shop.
At some point taxes got way to expensive so I sold it.
I would argue that its not so much the design of the engine in many of these cases, but that EGR was added to a diesel engine.
EGR is pure engineering hypocrisy. It shouldn’t ever be used on a diesel engine. You gain absolutely nothing but a ticking time bomb of critical failure.
Supposedly its put on there to cool down combustion to prevent NOx production and to give “unspent hydrocarbons” a chance to be burnt. But you wouldn’t have unspent hydrocarbons if your A/F ratio is greater than 18:1. And the best way to cool combustion is with cooler intake temps.
But noooo the socialists f@&ks that make the regulations don’t want you to actually clean up your emissions in the way that will reduce fuel consumption and improve performance, that’s logical and logic just isn’t allowed in government regulations.
Ok, I’m done ranting... but its your fault, you brought up EGR in a conversation about diesel reliability.
My 1980 Cutlass with a 5.7D engine runs just fine. As does my Datsun inline 6 diesel from the 70's. The Subarus has a problem with the double mass fly wheel. Often the sound is mistaken as an engine noise. The shop pull the engine and find no fault, then mysteriously after "rebuilding" the engine also find the flywheel problem. Selling it to the customer as the flywheel broke the engine.
The issues with the 6.0 Powerstroke could all be easily fixed. The 6.4 Powerstroke was intentionally made shitty by International
meifert2 not true the bottom end was very stout the rocker arms were weak.
Ol’ Mudflap the 6.4 is why Ford cut ties with International. It was literally made to fail.
That's the problem with the 6.0. To make it reliable ya had to do 10k worth or work to it. On top of the 70k bill for the truck.
ohiopower $10k? You must have gotten ripped off since the EGR caused almost all the issues and a tuner and delete is under $800.
meifert2 6.4 failures are a mix of poor early design of a scr mixed with top end that couldn’t not handle the high drive pressures of a compound vgt turbos. The engines do much better with a single fixed geometry turbo and deleted a tuned.
The 6.0 is fine if you know what you’re getting into and know how to bulletproof it. I own two. I got about 250,000 miles out of the bone stock Excursion I had. However, cold starts and blow by were issues by the time I sold it to a rebuilder. Which is where I purchased my second 6.0.
You can't make a good diesel that plays by *ALL* the rules.
Power, Reliability, Efficiency, Emissions, and Weight.
You have to sacrifice 2 to excel in 1.
My personal favorite is a lightly modified 6BT.
but I care about people, and I wouldn't do anything that worsens the NOX emissions.
my dad drives a toyota land cruiser prado with a 4cyl 3litre tdi engine , he has had it since 2012 and it actually runs pretty well till this day
Julian Daal yes, the 1kd-ftv is awesome.
Japanese can't make a good reliable diesel??? WRONG!!!!!!
My dad has a 1999 Toyota Hilux with the 3L inline 4 diesel and it is currently at 350k km without any problems. My uncle has a 1993 Hilux with the same engine and it clocks over half a million kilometers and i haven't seen the first mayor issue with the engine, Oh and it drives like a champ
Those really aren't super high numbers for a reliable engine. Usually an engine isn't considered to be super reliable unless they go over 600,000 km regularly. The diesels in the Hilux, however, are usually the most reliable option as the gas powered V6's tend to be pretty crappy.
i know. The first gen v6 is a crappy engine: low power for the size and kinda unreliable. Second gen v6 is way better.
I know that 500k doesn't sound like much but that was the last time i saw that mileage in the vehicle.... mi uncle daily drives the vehicle, maybe is reaching the 600k mark. i haven't been in the vehicle for a long time
First ever TDI engine was in Audi 100 C3 in 1989 and it was the 2.5 liter inline 5 turbo diesel, it was very reliable and legendary, but in Audi A6 b6 they made from a reliable and durable engine the unreliable 2.5 TDI V6. And I love old naturally aspirated American diesels
Typical emission standards - older audi q7's had the big ass v10s but nowadays the q7's have at most a 3 litr v6....
Q7 had V6 V8 and V12, the toareg had a V10
GoldmineGaming sorry, was about tow write v12 but that seemed kinda crazy, but now I know 😂 anyways I think you get the point
Oh yes I get it, I worked for Audi Sport as a mechanic nearly 1.5 years ago, the old Q7 with V12's were mighty cars and with the V8 too. I just left when the Downsizing started, the only car I drove with downsizing is the RS5..
GoldmineGaming damn that's cool dude 👍, it's true and sad about the engine downsizing 😔 and I'm kinda mad, well a lot mad to be honest, stupid ecologist vegan feminists
Still got a 4.0 V8 diesel though. Better than BMW's 3.0 I6 quad turbo og the Mercedes 3.0 I6.
You take that Oldsmobile LF9 but better head bolts in the and slap a turbo on it really wakes that engine up.
Now make the most reliable diesel please :)
I bet the OM engines from Mercedes would score the first 5 places in that ranking
Mercedes om616/617
Toyota 2L/3L
Isuzu 4jb1T/4jg2T
Vw 1.9 tdi
There you go
Lim Lany you've forgotten the Renault K9K 1.5 which also found it place in some new Mercedes Benz
Best diesel is mb's om606 NA !
Has he not allready done a video about that?
5.7 diesel wasn't made by Detroit Diesel as here was said. 6.2 and .5 was made by DD.
Peugeot deisel: slowest car I ever owned, multiple problems, ending with a blown head gasket.
Seth Kantrowitz Very old Peugeot had this. But some lives over 500 000 km.
I once drove a Pug 309 D, with the 1.9 NON-turbo diesel engine. My god, i could have got out and walked faster. Pulling out of junctions was scary as you needed a 0.5 mile gap in traffic to get going.
early 5.7 diesels used a standard 350 rocket block and were essentially a gas motor that was converted to run on diesel, later versions used a heavy duty diesel "dx" block that can actually be converted to run on gas. both engines had major reliability problems as well as pathetic power output
That Oldsmobile LF9 ... 5.7l - 120 HP / 300 Nm ... My '99 2.2l Merc has the same torque and 125 hp ...
SpecterH since when do americans know how to make diesel engines ? :))) All they know is just to increase displacement.
yeah but it's also about 25 years newer than anything that came with an olds diesel
At that time, they were the fastest diesels around 160-170 kph and the most powerful... All other diesels till the late seventies had around 40 to 85hp.
High end cars like the Mercedes 300 SD had a straight 6, 3.0l Turbodiesel and 125 hp but most were n/a.
So yeah... olds and caddys were heavy oil powered rocketships !!!
Americans know how to make diesel's if they want. Just take a look at the 6.6 Duramax, the 5.9 and 6.7 Cummins
My 2016 Merc with the 2.2, and a Brabus D2 tuning kit has 215bhp, and 420NM. And still does 68mpg on the motorway. The OM651 is the best diesel engine of this century.
My Dad had the '79 Olds Cutlass 4 door. It came with the 260cu/in engine that put out around 80hp and was a real dog-actually dangerous to drive. Then at about 50,000 miles a hose blew when my Mom was driving it and she said it lost power and just stopped-froze solid. So we had a 350cu/in installed and with the increase in power (120hp) we discovered the little turbo 200 automatic transmission was slipping. We found out that the turbo 350 automatic would bolt up, and then had a great transmission. The 350cu/in lasted about 30,000 miles, then had a cylinder crack with water leaking into the cylinder. Basically had a long block installed. When it ran, it ran well. But the last straw was once again (third time) the fuel injection pump failing. I didn't want to pay the $800 plus labor to repair it, so I paid $250 to have it hauled away. Was ashamed since it was a nice car to drive and except for the engine, was reliable.
sadly this video is just colections of myths heard from mechanics in india
hahaha. Sounds about right!
Myths from India? Nobody even talks about cars here. Not even mechanics!
MaceThePro true😂
even you????
ElectronicRedPanda if u dont like the comment then, dont respond to it
I’m surprised that the 6.0 Powerstroke was on here instead of the 6.4 Powerstroke. Usually on a 6.0, you could replace the studs, replace the egr cooler, and make sure you push it every once in a while to clean it up. The 6.4 just had so many problems that you couldn’t fix one thing without worrying about another.
The 6.0 isn’t that bad if you fix it. Same with the 6.4 it’s just the 6.4 is worse.
What? Toyota's D4-D are pretty good engines. 2.5 TDI isn't so bad, in fact they're much better than 2.0 TDI which are just shitty. Also, one of the worst diesel engines are Inline-4 BMW M47.
GTR Exactly , the early 2.0 tdi was a peace of shit and still is , everyobe complains about 2.5 just because it needs a bit more care to it.
2.0 tdi isnt shitty ether just need to take care of them
I personally dislike 4 cylinder engines.
so a 24v cummins and a 2.5 tdi share the same injection pump??
Remove the cab to work on the engine, lol, great design..
That's pretty much all diesel pickups these days. The engines are monsters that barely fit in the vehicle.
@@toomanybears_ Ha ha ha! And still they are so stupidly huge. Waste of money and time. The old ones before the ECU age at least made sense. Endless money pits for trucks that do what a Honda can do. Go from A to B XD
Get a real truck with 12-18 gears and 1L+ in every cylinder. If not for 4WD the big rigs got every advantage and much cooler. 13L V8 730Hp. Factory EU truck. Or why not 24L v12 2000Hp from factory :) Only wheel friction and money being a problem. You just tip the cabin to acess the engine in a EU tuck :) Remove the front wheels for better access.
@@TheDiner50 I got a 3500 dually to pull a large horse trailer, ~20k lbs fully loaded. You're not going to pull that with a Honda Civic. And it fits in my garage, pretty sure a semi tractor would not do that. I really did NOT want a 4 wheel drive but that's really all that's out there and it has come in handy a couple of times, we get some pretty heavy snows here on occasion.
The Detroit 6.2 and 6.5s weren't bad engines. The only real problematic parts in those engines were the horribly unreliable stock injection pumps, and on later 6.5s a badly placed controller that would overheat. Both aren't too hard to fix. Yes, they don't make much power, but they will last an extremely long time if cared for correctly.
Toyota diesel unreliable? thats hard to believe!
fidel catsro it's not unreliable, it's just not that good
ok amigo, i stand corrected!
believe it!even diesel Hondas are very shit and as you can see Toyotas too
Honda's diesel are shit indeed, they're not known of their diesel engines
My Only experience with a runaway diesel was a Toyota diesel. 82 pickup
Despite the 6.0L's reputation and its known flaws, it has been around long enough that you can bulletproof them well. Plus, any early 00's truck is going to be of the age and miles that it will probably be time for a refresh anyways, so that's when you do the work to the EGR, oil cooler, HPOP, heads and such. Not necessarily delete the smog devices outright, but replace them with better components and procedures. Lack of a DPF makes this relatively (kinda) simple and they can be reliable once the engine is done up right.
Now, the real turkey was the 6.4L as it was the first Powerstroke that had to meet the more modern emissions requirements. Add to the fact it was scrapped after only 2 years and you have an engine that is unreliable AND has a short production run, but also has far less support and creative solutions built to solve those issues for second and third-hand buyers.
From my point of view mazda's 2.2 diesel skyactiv is by far one of the best diesels in history
Yes! We moved from a 1.5dci Nissan Juke (horrible car I know, it was the SO s car), we moved to a 2015 Mazda3 2.2, what. An. Engine, there is minimal lag at all RPMs and no perceivable boost threshold. Plus, 70mpg(UK) on the motor way @ 70-80mph. The Juke wouldn’t even manage 50mpg at 60mph! The 1.5dci had a plague of problems.
mulymule12 also this engine works without adblue and the maintenance is cheap in comparisson with other diesels.
In my case i bought the 2.0 165hp instead of 2.2
Personally i prefer the Merc 2.2 diesel. Smooth and very refined. Power ranges from 136bhp to 205bhp depending on spec. The OM651, still used in almost all Merc ranges today. So good that Nissan are now using the Merc engine in the Infiniti Q30.
I love the 6.5, move the pcm and the fuse block, update the injector pump, and its practically bulletproof. The cranks are known for snapping cause of faulty balancers and bad metal batches, but that fix is a 6.2 bottom end with a 6.5 top end. They are not a 12v in terms of speed or a 7.3 in terms of factory strength out the gate, but itll get you, what your towing, and anything else there happily and with decent mileage. Dont forget the 6.5 lives in a fuck ton of Humves.
I miss the VAG 1.2 tdi
N VD97 1.2 TDI?
Okabe Rintarou Small 3 cilinder turbo diesel engine from volkswagen, nutorious for egr valve problems, high oil consumption and randomly blowing up.
N VD97 is that the same TDI they used in say, a 2011 VW Polo?
Okabe Rintarou Yep
N VD97 oh wow. I know someone who has that exact engine in their Polo
My parents had both 6.5 (and still has today) and 6.2 suburbans late 80's I liked the 6.2 simple and less shit to break on a family hauler of 1986 suburban unfortunately he sold that one and i ended up buying a 94 with the gas 5.7tbi for my family nice burb a bit thirsty but i would choose iron blocks over this aluminum shit sold nowadays
