I expected to see the Cadillac 4100 and Northstar engines on here, as well as Ford's 5.4L 3 valve
I'm gm guy, but I home to 5. 4 one was 2004 super duty 2 valve the other and 2008 3 valve expedition which I still have has 266,000 I'm still going one word and oil change every 3000,3500 miles

Just bought a new truck my old truck was a 06 5.4 150 313,000 and still going strong
@@winstonrocco1981 Agree, my 5.4 3 valve 2003 F250 clocked 195k still a strong work hose.....
My 07 f150 5.4 3v almost 200k never been inside the engine.
13:16 Utter tripe. Perhaps among those who don't keep anti-freeze in there for its anti-corrosive properties. Those were very reliable and powerful engines, a best of both worlds situation.
Wow I thought the diesel 350 engines from the 80s would make the list!
Properly maintained I've seen them over 300K. Most people who bought them treated them like gas engines.
My dad had one of those that went like 300k miles. The biggest issue (that my dad was tolerant of) was it eating injection pumps. He had the fuel shop on speed dial 😂
Olds 350
@@wymple09What, exactly, is "treating it like a gas engine"?
A guy i worked with back then bought one of these and the engine was completely shot at 35k.
The car was constantly at the dealership with problems before that and the GM mechanics told him everybody was having major problems with them.
idk who this guy is saying he got 300k on one, i think he's confused with a different engine.
I got so good at replacing the head gasket in a Chevy Vega engine, I could do the whole job in 35 minutes.
Steel sleeve fixes most Vega engine problems. I squeezed 190hp out of mine with a 4 barrel Holly 390,port and polish head and medium cam grind. It would smoke most stock V8s
@@Keith-rk4tdI am interested in you Vega build. I have a '72 Stinger.
Yeah! Those head gaskets could be problematic. I also threw rods in 2 blocks. To be fair...I beat the hell out of my '75 Vega wagon(I was 21 and it was fun to drive).
But they were easy to work on(one can lift the engine out by hand!). I installed a header and a Weber carb and drove it flat-out quite often.
My Vega problems were rust out top fenders
@Keith-rk4td I think Chevy had a recall on the Vegas because of the aluminum cylender walls.....
so you forgot the oldsmobile 350 diesel, the triton 5.4 spark plug launcher, the SOHC 4.0 explorer with the nightmare timing chains, the Gen 3 hemi that drops valve seats like its job, the SOHC escort 1.9, same issue, the cadillac catera (the whole car actually)
*_FORD SOHC 4.0 WAS ACTUALLY RATED WORSE ENGINE DESIGN FOR THOSE YEARS..._*
I had a 1994 Taurus with the 3.8L V6. I bought it from my former department manager, he had found a crack around freeze plug in the left end of the front cylinder head and fixed it with a rubber expansion plug and retained it with asteel strap, it also had a noisy rod bearing. After about 4 years, it started leaking again, so I bought a used head and installed it. I traded it in 3 years ago, still going strong with the rod bearing and replaced head at 245000 miles.
Toyota is recalling over 100,000 2022 and 2023 model year Toyota Tundra pickup trucks and Lexus LX SUVs due to a potential engine failure caused by machining debris left in the engine during manufacturing
P
The sad part is that the manufacturers are now putting out engines that will make these 20 engines look like they were dependable engines.
Fords Ecoboost. Absolutely hopeless engines.
Did anybody else notice the radial aircraft engine with a missing jug as an example of a failed VW engine?
@paulkurilecz4209 Yes I did.
Pretty funny and a testimony to the authors lack of automotive knowledge

Thank you for the list, easier then the video
Thanks for the table. Mine isn't on the list. Awesome.
6.0 and 6.4 Ford diesel engines top the list!!!
Ford 4.2 was a v6 truck engine !
You could get a 4.2L 225ci V8 in a 1980 mustang. Jaguar also used the 4.2 V8 ford engine.
@@markchatman9583 But that whole segment of the video showed F series trucks, so I think they were referring to the 4.2 V6 that came in base model F-150s.
@@Pooby1000 yeah it’s just one of those B-roll videos. The 4.2v8 was a piece of 💩 just like the 4.2 v6.
I had to play that part back, because I was sure it was v6 helped a buddy out with a F150 that had that engine!😅
Was thinking the same thing, then while describing it in f150s shows a brand new raptor, then a 12th gen eco boost and coyote.
Ford 4.2 v8 in an f150? Never heard of it. I think you meant v6.
4.6
@@davidbates4622 yeah but the 4.6 was a great motor. The 4.2 V6 sucked
The 3.5 litre Ford V6 with the waterpump inside the engine. WTH were they thinking...duh!!
That was a "bring it back to dealership" service thing. They planned on us having to bring it in to the dealer to have that water pump replaced. Planned obsoletion of vehicles has been a thing since the mid to late 80's.
just goes to show you they make these engines far to complicated. give me a plain old 60's engine everytime.
As someone else mentioned, the 5.7 Olds/Cadillac diesel conversions should certainly have made that list.
9:38... Huh? When did ANY G-body Regal have a 3.1 engine in it?? 🤦🏻🤦🏻♀️🤦🏻♂️
Ya , Gutless Wonder. Poster child for least HP per CID !
W body regal
I never heard of a Ford 4.2 v8 especially in the F150
1997 to 2008--F150 and F250's--Junk
No Northstar engines? No Cummins killer dowel pin? No Vulcan V6? Missed potential at a bunch of headaches.
Hey the push rod v6 Vulcan was a good engine mine has 275k and still going...the overhead cam version was junk!
I had a Vulcan 3.0 liter 24 valve V6 it was a running son of a gun
Triumph stag V8, yet it shows the ex GM Buick/Rover V8, WTF???
de eerste motor is een rover 3500cc,die tweede is de slechte Triumph motor,wat een hel was dat
Should have just called this Engines with best chance of blowing a head gasket.
Remember fords spitting out spark plugs
My Crown Vic literaly shot one through the hood
I got pretty damn good at catching them 😊 !
Made in Triton, (I believe) Michigan.
Hence the name TRITON ENGINE.
Yeah the fords loved shooting the spark plugs out
they still do!
The 305 chevy v-8 was a great engine when properly maintained.
had 400k on mine
Mine died at 469k, ran like a champ until it decided it was time to retire.
Reliable just no power
@@brianhawk6979 They had enough power for a sedan. They moved the 80's impala and caprice along just fine and got great gas mileage.
@@brianhawk6979 Having them in a 5 speed manual felt like a power boost.
I had a Mazda RX2 wankel rotary. It was very fast until it blew the rotor seal at 30k miles
Much as I loved my Acura Legend I'm somewhat surprised that the 3.2 V6 32A engine didn't make the list given how notorious they were for head gasket failures. I replaced one engine for the problem but when the second one started to go I finally dumped it for something less expensive to repair.
The 1970s Vega engine should be at the top of this list.
my sister had one of those.... ran forever.!!!!!!!!
Junked the 4 cylinder replaced with a 350 V8 out of a 72 Chevy truck and would smoke quite a few muscle cars 😁
@@truthbetold9923 i guess so.!!!!! i've heard of a few people doing that....
I had one too, it leaked oil so much ..We used to joke it had a self changing oil system. 😅 I drove that car for 3 years, and when it finally quit I sold it to a guy who put a 327 in it.
12:30 - I had a 1988 Chevy Celebrity Wagon with this engine. In Chevys, it was called the "4-Tech". 2.5L inline 4. Old Pushrod and Rocker-Arm valve train. It did have EFI and fully Electronic Ignition.
Surprisingly, I had no significant problems with mine. Sure, it didn't have much power but like I mentioned, it was very reliable!
I remember most of these, Thank's for posting.👍🇺🇸
I never heard of Saturn problems. I had two with 250k. I knew other people who had ovet 350k
My dad swore by Saturn's. Never a major problem. My dad is legally blind 😂 his wife would drive him. We called him Miss Daisy
years ago I bought a Saturn with 250K for $900 and when it reached 350K I sold it for $900
You mean a Shiturn?
The classic " Vegamatic" caused a boom in people becoming mechanics . :) The Vega is the undisputed #1 in my era 👍 Had 2 friends decide a 350 would work much better in that car
Shown the 70s Skylark instead of the front drive 80s Skylark
The 255 CI 4.2 V8 was used in the early 1980s. The truck used for this video had the 4.2 6 cylinder.
Moral of the story, underpower = head gasket failure and never comingle coolant and oil.
None of this video is accurate
I wouldn't say "none of it", but I would definitely say most of it.
I owned a '94 Mustang 3.8 liter V6. An otherwise lovely car with an engine that transformed that road horse into a swayback, or to put it into the vernacular, a Mustink.
I always say replace junk engines with sb chevys
If you can keep a quad 4 from overheating they last a good while i put 250000 on one
Yep, I had 2 Achieva's that both had well over 200,000 miles that I used for deliveries. I had to do the Cam chain tensioner modification on one but that's it!
I had a '97 Skylark with a Quad 4 in it. I ran it up to 260,000 miles before I had to give up on the car due to too many NY winters
Still underpowered and rough as hell though.
You forgot the FORD!! 1.4-1.6-1.8Ltr CVH engines dohc 4 pot head gaskites leaks MK3+4 Escourts Seira.
Missed the Toyota 20R 4 cylinder engine head gasket and warped head problems.
The camera work is a shocker in this video. It'd be great if the cameraman did his job and held it still so we could see the engines.
The Ford eco boot with the wet cam belt should have made this list, they are complete junk.
I will never buy an Ecoboom.....and I buy alot of Fords.
@@northdakotaham1752 same....
10:06 If you put the problem solver intake gaskets in it ONCE, it was a VERY reliable and smooth running engine.
When I used to go to buy a used vehicle whose reliability I wasn’t that familiar with I’d call a good friend who managed a salvage yard and ask him about demand for the vehicle’s drivetrain components. If he had a lot of the vehicle’s parts in inventory I figured they were pretty reliable. If he couldn’t keep them in stock I’d avoid them like the plague.
the caddy 8,6,4 just unplug 1 wire and it was a standard V8 that was GOOD.
I'm surprised to see the Chevy 3100 V6. My parents had a baretta with that engine and drove it over 200,000 without any engine work needed.
You shouldn't forget on the Chevy 2.4L 4 cylinder, the placement of the alternator, caused overheating and failure of the alternator. We replaced 4 on a Corsia with less than 165,000 miles on it.
Where's the Northstar (notorious for going supernova) or the S85 (with it's tendency to eject it's connecting rods after the rod bearings failed)?
I have 2009 dodge charger with a 2.7 that has 208000 miles on it, however I did change the oil every 3000.
I've got a 2008 chrysler 300 with 271,000 miles on it. Drive it every day. I've replaced 2 fuel injectors, the radiator and the key switch. Owned it since 2009.
ford 4.2 was a V6
I expected to see the Ford Triton engines. Prone to blow spark plugs out.
The spark plug blowout was due to the low plug torque spec from Ford (14ftlbs). Take it up to 22-25ftlbs, use only Motorcraft plugs, no antiseize, and you will never have a problem.
03 5 4l 2v with 310k. Still running strong.
Triton engines were junk from the factory
Mine has 192,000 miles on it.
Good call Gary.Being a mechanic for over 50 years,i can't count how many of those shitcans i repaired.
The 2.4 Quad 4 was replace by the 2.2 Twin Cam and the 3.4 V6 was also an option on those Pontiacs.
Some of those over heating make me think i dont need the max AC, the engine bay needs the max AC perhaps i need to make a vent for ac to the engine bay lol
The 2.5 L GM was Notorious for egg shaping the cylinders
The 2.2 was preceded by the worse 2 0
I don't think a stock Chevy 305, had a flat tappet cam either? Only hydraulic cams in stock trim?
I think that they mean as opposed to a roller camshaft.
😅
I'm amazed the 2.6 Mitsubishi didn't make the list.
Rover K series 1.8 fourcylinder .
It was a headgasket eater .
It was also 1.4 , 1.6 & 1.8 . I was a Rover foundry metrology technician Quality engineer from 91 to 05.
So it was your fault. haha.@@jeremywentworth1833
PSA/Stellantis group 1.2 Puretech and 1.6 THP engines also need to be on this list. Ford first generation 1.0 Ecoboost also needs to be on this list.
With the subaru 2.5T, the ringland failure is, in part or in whole, is because the rings are located too high up the piston making them vulnerable.
Sadly the new cars will self destruct just after the warranty tuns out .
Nissan 2.5L found in the Altima is excellent…
Notice how they keep saying.. " high engine repair costs " this made dealerships millions ... of course they will keep it in production.
3/4 of the way through and this trainwreck of a video never fails to screw up at even greater rates.
I have to testify that I drove a 2000 Grand Am to a total of 217,000 miles on the original engine, never burned any oil. The body of the car fell apart around it, but the engine was indefatigable.
No Vega engine, no Olds 5.7L diesel, first gen Ford Escort? These engines were a LOT worse than the 305 Chev, the 3.1L Chev, or the 3.8L Ford
I used to have a joke Yugo "You only go so far and that's it!"
Surprised the old Pinto 4cyl isn't on here.
I had one in the 80's and it literally burned a quart of oil every 50 miles before the engine had complete failure at 40k.
It was hilarious looking in the mirror after waiting for a stop-light and seeing a huge smoke trail 😁
Sometimes people behind us would turn on their wipers in full sunshine 😆😂 We were in HS so we didn't care😁
I never met anyone who got more than 50k out of those engines.
Vega was the competition to see who could smoke more. I remember . We would stop for oil and check the gas era.
the 8-6-4 was the worst idea because it didnt have the technology of today but i would have tossed the northstart engine on here instead
The Subaru turbo flat 4 LOVED to chuck rod bearings.
Anything that ever said Mitsubishi on it you knew it was junk right away
Quad fours were very popular with speed record cars of every description at the Salt flats
Chevy 305 had horrible cams. The lobes would just melt away!
You forgot to mention the 2.3l Ford ranger engine for its lackluster performance and head gasket failure
Loved my Quad4! Key was to catch head gasket right away(about 100K).
You forgot the Ford 6.0 liter diesel engine!
The 6.4L diesel from Ford was one of the worst as well.
Both engines are international truck.
@@marena4136umm you mean Navistar and gM are made by Isuzu (so fancy name added-Duramax or Dirtymax as it has become better known
The 3 liter Mitsubishi was preceded by the worse 2.6
I just watched a different video stating that the 3.0 Toyota was one of the best. I had a 92 4Runner that blew a head gasket at 50k and the fuel injection failed shortly after that repair. The 3.4 was a big improvement.
Neon head gaskets blowing
i like the iron duke on old concept but relable
I mine has 154k with the 5 speed.
Mustangs with a V-6 still can’t stay off the sidewalks.
How could you miss the Cadillac HT 4100
Power or endurance??
OK...tell me how power is related to reliability.
Welp now that u detect the problem, make, sell improved after market parts to make said unreliable inventions reliable again
Worst in my personal experience was the Ford 2004 6.0 liter diesel turbo in my F350 crew cab long bed.
*_WORSE FORD ENGINE EVER BUILT WAS THE 4.0 SOHC ENGINE, WEIRD TIMEN CHAIN CONFIGURATION, BLOWING HEAD GASKETS AND CLOSED LOOP COOLING SYSTEM WAS A ABSOLUTE NIGHTMARE OF A VEHICLE!!!_*
My first car was a present from my grandfather, it was his Mercedes Benz 280 SE. He bought it in 1971 and drove it until 1979. He gave it to me as a gift for my 18.birthday, at the time the car had 142,000 kilometers on the speedometer. I had the Car for almost 10 years until the engine collapsed, at this time the speedometer was up to 589,000 kilometers....the same engine and i had no major problems with it, except normal wear and tear. I visited once the Mercedes museum and they showed me a Mercedes engine with over 1,000,000 kilometers...that's really remarkable, isn't...!!??
Those days, MB made the best cars in the world, super quality in every detail.
Good 4 U, I actually waited for MB 2.8ltr 6 cyl.engine to be in this listing...But theres known phenomenally workin MB 2.8's out there, cant say whats the deal with em but here in Finland those MB 2.8's are famous boatanchors...
the fourcylinder in my dodge caravan had a history of head gasket failures
Probably 2.2 or 2.5, other than head gaskets they were fairly dependable.
@@sst568 the dealer told me it was the head gasket that caused my problems.
probably 2.6 mitsubishi junk they put in early caravans
Oh excellent, so Chrysler had this ingenious water pump design; Ford saw it, and decided to add it to the lineup!!??
The absolute worst: the 226 cubic inch side valve I-6 that KF used. It was never intended for use in a car. BTW, I have driven KF products. Junkboxes.
The 226 that was in Kaiser cars was a slightly larger bore version of the pre-war Graham engine, and the Graham was indeed a car. You are thinking of the 226 industrial version.
I expected to see the ford triton motors for spark plugs blowing out
FIAT... Fix It Again Tony....
GM = got money.????
Ummm the 4.2 was a v6
6:11 This was a 4.2 L V6. The 4.2 V8 was stopped in 1983.
Did ANYBODY build a good engine?
International Harvester IMHO.
Volvo 😊😊
Thank God I missed those clunkers... Goober Motors definately tops the list
Less than a minute and a half in and already show two vehicles that are inaccurate with the engine being discussed. Time to bail on this channel.
Dont these companies test the new engine designs?
No, we do Lol
Any potential for corporate politics and corruption will be found abundantly in almost any automobile manufacturer. The culture is among the worst in any industry.
At the top of any automobile manufacturer is the sociopath manager, the smooth corporate operator who won't hesitate to pass horrible liabilities on to the consumer.
GM 454 SOME OF THE ENGINES WERE LEMMONS OVER HEATING
"Chrysler continued to use the 2.7 V6 until 2010." Lol
1975 Honda CVCC. 1976-1979 Honda 4c blowing head gaskets.
The Chevy 2.8 V6 was a real piece od junk too!
231 cu in V6 Engine in a 1979 Buick Century 2 door coup - burned oil and died after 80,000 Km .
Never again would I buy a GM product .
.
I had a Lumina for 6 years and it was the best car I ever had!!
