I have the 6.7 on our ranch. Pulls heavy trailers with livestock and/or feed and it works great. The trucks in this video... A laughing stock to an American producer. Stay in the city and keep pretending food comes from the back of the store.
@@jayirving6996 On my 06 mega cab my moose antlers stay out bud! I'm use to them like that its not always about looks lol dont be a goon! I tow trailers almost every day and im not ganna waist my time adjusting a mirror every day twice a day minimum. i have 4th gen mirros with the large convex. You have to adjust that by hand so thats not happening lol
Owned both and have love for each of them. 6.7 will work if deleted and I would recommend arp head studs. The 68rfe 6 speed automatic transmission is great when working but prone to failure with hp increase unless built. The g56 6 speed manual transmission is probably more reliable but not as much fun on the street. Like said in this video the 5.9 is more reliable but has some disadvantages too. If I was going to have to pick between the 2 I would pick the 5.9 just because of its overall reliability. That being said I really do love them both. Just my opinion. To each, their own.
I have 2 of the 5.9 / 12 Valve in 1 ton trucks I uses on my farm and I love them. I retired from Union Pacific Railroad as a electrician. The newer Technology is great as long as you have a standby mechanic to keep it running. Union Pacific Railroad uses older Locomotives with mechanical blowers in there Local switch yards till about 2012, because all you had to do was fuel them check the oil and run the shit out of them. They were bullet proof.
Simply put...the 6.7 was needed to achieve more power but still meet the more and more stringent emission requirements than the 5.9 could. The 5.9 is still the dominate engine in the performance world.
The 5.9 does well in the performance world but the big thing for performance cummins guys is a 6.4 cummins. Alot of racers and sled pullers use a 6.4 these days and yes I mean 6.4, not 6.7.
This is a joke of a comparison. Comparing pre emissions to post emissions is apples and oranges.... and lets face it the old 5.9 12 valve that is quickly eliminated from comparison here is the only one of the engines that can get 25-30 mpg and run a million miles... mainly due to... yup NO EMISSIONS, and mechanical everything.
@@Redsfanatic32 I've owed all three and my dad's 5.9 common rail, gets 17mpg with a 6 speed and 3.55, his 99 vp44 24v 5.9 got 18.5-19mpg with a 5 spd and 4.10 gears, his 95 12v 5.9 with an auto gets 19-20 with 3.55, and my 96 with 12v 5.9 gets anywhere from 20-25 with a 5 speed and 4.10 gears sitting at 400k miles, I got 20 pulling an 18k lb trackloader
@@chazlewis900 I will agree the 5.9CR is just reliable but fuel mileage is no comparison. I own an 06 5.9 six speed and 3.73 rear I only get 15 empty. My brother has a 97 12V 5 speed with 3.73 rear and he get 28 empty.
Being a former diesel mechanic I love my 5.9 24v because it is so simple. With the NV4500 trans it makes all the power I will ever need and no repairs after 20 years .The only weak link is the lift pump starving the VP44 injection pump. A good fuel pressure gauge and keeping the filter changed is so important. Unless I wreck it it will be the last truck I ever own.
My wife and I are full time musicians and full time in our 26 foot travel trailer (30' overall). We pull it with our 2007 3500 4X4 with a fully enclosed fiberglass CargoBody cabover work van style camper. We sought out the last 5.9 (early 2007) for it's better mileage. With the cabover semi-empty (around 700 lbs) at 55 mph on level freeway, we got 25.5 mpg. Now that the camper is full of tools, and pulling the trailer (8,000 lbs), were averaging just shy of 16 mpg, which is where the 5.9 really shines, especially now that diesel is so expensive!
Went from a 6.7 to a 5.9. I tow aprox 70,000 a year. Don't want to up set 5.9 folks, but for my need I've found 6.7 to work for me better. My 2010 6.7 provided me with 210,000 miles in that stretch I replaced 2 water pumps 1 alternator. All other repairs were not done on the power train. The truck I'm currently piloting is a 5.9. It works ok, but I have had to adjust my trip times as I'm slowed more often than in the past. I also have a hard time maintaining an exhaust gas temp that will not damage the truck. Learning to drive with new limits is I guess a personal problem to get past. The up side to this new, to me 5.9 is the fuel mileage. My new 5.9 gets almost 50% better mileage. That is the main reason I'm keeping it.
Not bad, but you do complicate the issue with 12 more valves. Not to mention the added cost for the conversion. However it is a great choice when compared to any of the computer run machines.
Well you mention deleting things on new trucks and talk about adding things like new turbos so what would be best is to get a junk yard 24v cummins then converted p7100 this way you don't have to reprogram ecu's there's no way the ecu can change mechanical pump
Im putting my 182k 02 24v in my 06 megacab with that configuration when the motor thats in it goes its got some time left though its only got 230k right now
It does not reduce reliability, it removes all reliability as 6.7 emission systems will fail. I own both, currently 1 6.7 (have owned 2) and 4 5.9 trucks. For driveability/street both being modded the 5.9 wins period. For pure power/torque (max hp pre-loading boost drag racing/tractor pulls or 800hp or less towing) 6.7 is king, there is no substitute for displacement. That being said, you will spend 1-3k+ a year cleaning/replacing emission systems (that are proven to not reduce emissions in real world applications, reason they are used: invest/law require to buy/use) on a street legal 6.7 as you warranty does NOT cover these systems, read it. Now if you make the 6.7 illegal for the street by removing the egr and dpf and def systems it is the superior power plant for max hp applications and just as reliable as the 5.9. If you want to understand why the current emission systems do not work, ie do not help the environment, they reduce power when in action thus you press the accelerator further down burning more fuel..... That is why 10-15 max mpg 6.7 towing, 16-21 mpg 5.9 towing both trucks making the same horsepower. Food for thought.
The F--yards in the government fail to recognize that when it comes to diesels, choking them with emissions crap results in higher fuel burns on bigger engines and ultimately MORE EMISSIONS...
I've had and worked the heck out of both and the 5.9 is more reliable and better mpg and I think it sounds better but the 6.7 is still reliable but when you get rid of all the bull shit on it it's definitely much stronger
5.9 is a more reliable engine, more fuel efficient, however the 6.7 pulls and works so much better! I’ve owned and worked both.. as a daily, I’ll take my 06 5.9, if I’ve gotta haul heavy weights and push a lotta wind I’ll take the 6.7 hands down.
Hey man, i have been watching a couple of your videos recently and just wanted to say your doing a great job. Thank you for your clarifications and knowledge on the subject, you explain things very well and i just wanted to say job well done.
Also you have to take into consideration of the ho second gen they’re kinda rare but mine has 535000 miles on it and only been through 2 fuel. Pumps 1 starter and 1 turbo but if you’ve ever been in the ho second it’s a totally different animal
The info is great, but those trucks look about as dumb as a 250 pound 6ft5 man in skinny jeans...trucks with lil tiny wide tires LMAO! A mans truck needs mans tires urah!
@@_Ranger01_ because people are jealous and/or have to have something to hate on. I don't get it either bud. The way I look at it, everyone is different. If everyone had the same mf style truck it would be pretty boring if you ask me. I like all the different style modded trucks.
@Dobbies Revenge calm down sugar cakes...lolol. all guys are saying is it looks really funny to lift up a truck - then put tires on it ud normally see on a lowered oldsmobile in the hood. Most guys lift a truck for off roading, but yes they can do what they want with their truck n enjoy it lol. Gives the rest of us truck guys something to laugh about =))
I have a 2001 5.9. Straight up the 5.9 sounds so much better. I still love it when I go into parking lots and heads turn. Obviously sound doesn’t mean it’s better but I like it.
I have more than 1 Cummins engines with emissions still intact and operational with over 750,000 miles and a couple over 1,000,000 miles. Requires more maintenance but doesn’t make them unreliable.
I have three also 2000 dually 2wd 170000 2004 dually 4wd 140000 nv5600 and 2017 dually 4wd 30000 and it’s sold guy is coming to pick it up in about 2weeks epa has ruined everything!!
I've own Mopar since I started driving in mid 70's. Challengers, RR's, Fury's Chargers, trucks etc. I've been away from classic auto seen for awhile now / was looking for a project. I found an unmolested bone stock (except 35's and aftermarket radio), 97, 5.9 P-pump w/5sp with easy 222,000 miles no rust CA truck. From reading the comments... I think that I made a good choice. Thanks for the upload.
You can upgrade the 6.7 by installing the 5.9 head, injection system, and ecu. Firepunk Diesel has a video on that While there may be some benefits to running the stock vgt turbo you will quickly find its disadvantages if you’re going for maximum power. It is actually quite inefficient with a high drive to boost pressure ratio so even if you’re running your truck basically stock you’re still better off with a relatively small fixed geometry turbo (BorgWarner S380 or S400) There are a lot of other parts that interchange on these engines such as water pump, oil pump, camshaft, valve train, front cover, etc. The 6.7 will bolt in to a previous generation truck with no modifications. This video mentions head gasket failure- the 5.9 head gaskets have been known to hold very high boost pressures even when using oe headbolts this is not the case with the 6.7 Both motors can make over 1,000 hp with compound turbos and larger injectors. Pretty much the only reason for Dodge to make the switch is emissions control. This increased displacement allowed them to comply will still competing with Ford on power output
Thanks for the vid. I always wanted to know the differences. Sounds like both engines are good, it just depends on personal preference/use. For me, I'm glad I have the 5.9 version for reliability as I have no need or desire to add any performance mods. I have an '03 3500 Ram dually 4WD with the 6 speed manual I bought used in 2009 with about 55K miles on it. Almost 12 years later now, it now has a little over 135K miles on it. I only use it for travel. One year it sat for the whole year in the garage, which wound up costing me over $400 dollars to replace the Optima batteries. I now take it out once a month for a short drive, about 30 -50 miles to keep everything working.
One thing about the 6.7 is the rod angles which is a weak point vs the 5.9. 6.7s bend rods easily when lots of fuel is dumped at low RPM. Would be a good idea to go with forged rods if you're pushing more than 1800 ft lbs of torque on a stock 6.7 bottom end.
@@charlesisbell4340 5.9 had no emissions other that a catalytic converter. In 2007.5 with the move to 6.7L stricter emissions standards came in to play.
God Bless You all. All Glory to God! Repent and live for God!! Romans 10:9 “if you declare with your mouth that Jesus is Lord and believe in your heart that God rose Him from the dead you will be saved.”
i owned a 98 6 speed single cab. traded it for my 03 auto. later bought a 13 auto. other than the transmission in the 03 its been a hell of a truck. still have it and the 13. wish i had never got rid of the 98 tho. as far as pulling that thing was a beast. if i could find another one in good shape i would buy it in a minute. far as the engines go i would trust the 5.9 over the 6.7. plus you dont have to spend $7-$8000 deleting them to start adding power.
what all have you had to do to to the engine, tranny, and truck get those miles? I've got an 06 5.9 with only 143,000 miles. When will I need to replace serious parts before it's not worth keeping the truck?
@@kaylatuttle9988 transmission at about 220000 the rear end at 190000 the driveline is original the engine has never had the head or pan off I replaced the injectors at about 300000 and the water pump even though there was nothing wrong with them 1 alternator 1 fan hub
As a Cummins tech I will tell you a 5.9 has it all over the 6.7. Just a 12 valve 5.9 will net you 50% more than a 6.7 and it’s all mechanical. Zero issues.
6.7 with vgt is in another league towing heavy, and the 6spd at with it makes it so much better than any 5.9 truck ever dreamed of being The 6.7 doesn't "blow head gaskets", the owners do when they push drive pressure beyond the compressor map safe efficiency range, by running super duper cool race car tuner boxes to add 300 hp Anyone who says otherwise has never used both, the 4x4 5.9 trucks in tow mode are screaming at 65mph, while the 6.7 truck can tow in 5th or 6th and run 80 loaded to the hilt at an easy rpm, although 5th is better for it obviously The riced out trucks at the beginning were definitely comical The 5.9 has no emissions garbage so it will always be called the more reliable engine, but the dpf has nothing to do with the engine being reliable or not, that's a totally separate emissions system.. They're both the best engines to have ever been put in a light duty truck and probably always will be...
Ooooh. Shiny🙄 why have 4wd if you dont want to get it dirty? And it looks so stupid when you see these mirrors in the towing position all the time. I use my truck for what it’s made for. WORKING and TOWING.
What bothers me the most is why the 5.9 litre Cummins was ever replaced by the much larger 6.7 litre Cummins? I would think that the 6.7 would be fine for a Class A motorhome, and heavier duty trucks, but for a truck like the Ram 2500 and 3500, etc., the 5.9 litre would be perfect.
I have a 1991 Dodge duly 35 runs great never had any issues I have over 1,000,000 miles does not smoke clean body and motor I just recently changed the fuel pump injector pump rebuilt it put a new one other than that no problems runs great
@@Man_in_a_Gucci_Suit no way of proving it. None of the first gens would clock that many miles on the odometer. Gears always stripped way before. Mine quit at 181k.
5.9 24v Cummins is better!! Conveniently easy to fix and work on. Display raw natural power. And loud. I live waking up my neighborhood. 🙋🏿♂️😂😂🤣🤣💪🏿🐎🍻🤷🏿♂️
I've owned all three models of the engine and understand each was a well thought out natural evolution of the prior ones. My 12 valve had 400K on it when I sold it and its running around yet today. My 24 valve 5.9 was just as dependable but suffered from poor quality components such as step pump and water dispersal system. My 6.7 has ran flawlessly for 188K with only minor issues with the TIPM. Cummins is in a different league than the competition so any comparison is pointless.
Problem is, everyone is on the delete train. You don't need to delete the emissions systems.... Then, when they have problems with their engine, they suprised pikachu and blame it on the emissions system, creating a false narrative. The engine was designed to run with the equipment it has. Not run with a S400 turbo, deleted egr system, dpf, and 200 HP injection map in the ECM.
2006 5.9 is a great platform for those who want great reliability and the ability to make great power without hurting the pockets; G56 manual trans is even more desirable.
I have an 2007 HO...I miss the Allison from my Duramax so i'll be putting a 6spd Allison conversion in my Ram when the 48RE bites the dust. Ram honestly better find a 10spd Aisin pretty quick...GM and Ford are winning in that dept with mileage and better shifting.
The 2003-2007 actually does have egr. It has in cylinder EGR via the camshaft. The lobe separation anges are closer than on the pre 2003. 98degrees vs 106degrees I believe. Closes exhaust valve a little early to trap exhaust gas.
SlimJim, Hopefully you will see this question... or anyone else who knows... tia for your reply. Will an older design cam eliminate the IN CYLINDER EGR ???...
@@RJ-sr5dv Hey buddy. From my understanding, having the vp44 24 valve 98.5 to 2002 camshaft is the best stock camshaft cummins ever put into the 5.9. In short answer, yes, a cam upgrade will eliminate most if not all of the cylinder egr but it should be noted that cummins also had other variables in the mix to achieve in cylinder egr, and to be emissions compliant, such as the smaller turbine housings on the he341 and he351 turbochargers as well as different emissions friendly ecm programming and I'm sure that the piston bowl shapes, injector spray angles, injection events (which are different from 2003-2004.5 to 2005-2007) are a factor as well. If you do a cam swap, it should take care of most of it but I would do custom tuning too from a place that has tested the tunes on a dyno with that cam in a common rail engine and with close to the setup that you will have. Hope this helps brother!
Luck me I have both now In My garage. The 2nd gen (95) 2500 complete mods on the engine and runs around 350 hp. It sits for now since I broke the input shaft in the transmission ( I have a Billet triple disk torque converter) too much power applied to the Billet shaft ? I don't know but will find out soon. The 5.9 is just plain fun to drive. I drag race a 6.7 a stop light ( really really dumb couldn't help myself) he beat me off the line but once the triple disk lock in I had him. I never done that before and won't again but what a rush for 65 year old guy. I install new 4 exhaust. When started it for the first time my wife came out house and said it sounded like a big rig. That made my day. I just bought a 3500 6.7.for towing the 5th wheel the 6.7 has the 5.9 beat for low end power and the exhaust brake and just plain comfort of driving . I bought the 5.9 new and may sell it one day but It would be like parting with a good friend. I know that sound really lame. But it is what it is.
My 2009 6.7 was a pig until i deleted everything... it then became a truck! Never another problem and it has 450,000 kms. My 5.9 has 450 k as well an it runs even more reliable. The 2 huge problems i have with the 5.9 compared to the 6.7 are lower power and the POS 48RE compared to the 68...I'm actually thinking about a CA conversions Allison conversion... so expensive though.
My 1st 06 was so reliable and powerful I had to get another one, I have had 211 vehicles and the 06 dodge 2500 has by far been the best and most reliable
I vote for my 98 12 valve with a swapped in 6 speed manual,reliable, makes decent power ( not much done besides fuel plate) and gets great fuel economy Oh an I almost forgot P pump baby!!!
1966cambo Yep, that’s the best combination ever in the dodge. I’ve got a 2001 with the six speed, almost rebuilt it to a p-pump 24 valve, but thought why not just get a 12 valve.
I have a 2006 2500 with a 5.9 and my brother has a 2010 6.7. Almost identical build trucks and the 5.9 I drive will out pull that 6.7 any day of the week. Can’t talk on the newer ones though.
How I see it both are good but Fall into different categories the 5.9 for towing /traveling the 6.7 drag strip racing and messing around but at the same time both can do the two things 🤷♂️ just my opinion
@@brandonshattuck3737 they getting stuck with soot? Our vgts on our fire trucks do good but we use the exhaust brake all the time. My 6.7 hasn't had any issues yet knock on wood haha. I use the exhaust brake frequently as well to try to keep everything freed up
Can we please, for the love of God, make it illegal to have low profile tires on trucks. It makes the truck pretty much useless and it looks stupid as hell too. I want to get a petition together ASAP while Biden is still in. Since he signs anything put in front of him
This lad is apparently telling us about two particular years of these engines, (or he is talking only about pickup truck engines without telling us so) he is not right about my early 2000. 5.9L Cummings (260 bhp on a Spartan Summit chassis) that is in my RV. It has 24 Valves (it says so on it's valve cover) a mechanical fuel injector pump (rotary style, electronically controlled) and exhaust breaking, a combination that he said isn't so. (it has no DEF or ERG) It does have quite a bit of "turbine lag" which he didn't mantion. Ron W4BIN
@@Dustrunnersauto the 400hp with CGI block I believe no longer has siamese cylinders. Siamese cylinders result in bores that can go out of round and are undesirable for that reason.
Actually there is no passage between 1 and 2 cylinders (or any of the others). If everyone here can image lining up 6 coke cans in a row. The siamese cylinders are joined like that. There are provisions for improved flow as close as they can get so that there are no cooling issues between the cylinders. The rest is basically the same as previous years with coolant flowing around the cylinders on each side. Coolant can also flow from side to side at the front and rear of the block. Siamese cylinders actually add a great deal of integrity and rigidity to the engine block. Reply
I have a modified 6.7 and two stock 12 valves. I have not drove a truck that makes more power then my 6.7, but it was very expensive to buy and build. Both 12 valve trucks are very reliable other then transmission issues. I don't think you could build a 5.9 to a 6.7 potental, but the 5.9 is a very reliable engine, especially the 12 valve. The second gen 24 valve VP44 5.9 engines make good power but suffer fuel pump issues (they can be fixed though). The third gen 5.9 common rail engines make good power, they are reliable, and they can be built to make awsome power. They can give a 6.7 a really good run for its money, but when comparing apples to apples the 6.7 will out pull the 5.9.
Jeremy Smith what if you just want a daily driver and towing a max of 14,000 lbs a few times a year and go off-road a few times a month? Please tell me 12v 5.9 lol
Ohio Till I die I think if ford put the Cummins in factory I would have a Ford I’ve had a good bit of issues out of the electronics on the truck itself
I’ve got a little over 375,000 miles on my 98 12 valve 2500 4x4. Replaced the starter 4 times, alternator twice, transmission twice, clutch, flywheel etc, once, but it made it to 350,000 miles though. Several sets of tires and brake pads. 2-3 sets of batteries. It’s never left me stranded (knock on wood). Truly a truck for the zombie apocalypse. Ha! Lol!
I own 95 12 valve 5.9 stick Also own 08 6.7 450 auto deleted My fav is the 5.9 virtually bulletproof ... although having great issues maintaining the body
Yah forget about the engine that put Cummings on the map for pickup truck moters. I own a 12 valve and wouldn't trade it for one of those newer pieces os
I just bought both lol got a 89 5.9 and love it all around I bought a 2012 brand new and love the power the 89 is stock the 6.7 is deleted and tuned and I have put over 200k on the 6.7 and pulled a lot of heavy heavy things and I don’t treat her nice and not a single break you must build the truck for the task your using it for to get the best truck
I think the 5.9 is a lot better, they are more reliable, and will last longer since they don't got all the emissions crap, plus they are making the newer diesels even quieter, like who likes a quiet diesel, diesels are better loud
I have a 2nd gen 24v and a 3rd gen megacab they are both rock solid and i know many people with 6.7 that that love theirs and are rock solid i like them both and im getting a 2012 6.7 megacab because all those ive ever been in have been amazing
Modern pickup diesel engines sound lame. I remember listening to a stock 6.7L Powerstroke once & I couldn’t tell if it was a Powerstroke or a 6.2L Boss. It’s so muffled u can’t tell the difference
Honestly. I think all turbo Diesel engines are pretty amazing. They each have their flaws, but all can be made “bulletproof” without a whole lot of money. I have a 2011 F250 with the 6.7 diesel. I’ve done a few things to prevent failure and it’s been nothing but outstanding work truck and fast. I love the Cummins and duramax seem great too, Allison transmissions are always nice. But a lot comes down to maintenance. Diesel is a different beast. Myself, I like to drain my fuel filter every so often and replace them bout every 3 oil changes. Most people won’t and bad things happen
@@braveheart2785 well. I believe I read that in a manual somewhere to change them every 15,000 miles, so 3 oil changes for me. I learned that for a Diesel engine the fuel system is a huge part, expensive, and the fuel pump and glow plugs rely on clean diesel for lubrication. And the fuel filters are cheap too. 1 fuel filter, 1 fuel filter/water separator.
All 3 (includes 12 valve) are winners. 12 valve for complete reliability. 6.7 for the ultimate power. I've got the common rail 5.9, which i'll be keeping for quite a while (the non-emission reliability). One item NOT mentioned is that the 5.9s are getting old. the newest being 14 years old now (mine :-). A 12 valve would make an awesome commuter, while a 6.7 dually is going to be your mass hauler. I.E. depends on your use. In the end, get a Cummins!
Yessir towing is the point of the cummins, people joke on my grandfathers 24 valve thats been passed down to me but i find it funny that these kids have tow mirrors on their trucks and ridiculouse rims and tires and they aint even using it for what its meant for. So what i cant roll coal, i can tow a damn church.
you have the injector firing voltage backwards. We are working through this issue trying to run the more reliable 6.7 injector in a 5.9 truck running the 5.9 ecm. The 5.9 injectors fire at 18v and hold at 18v the 6.7 injectors fire at 24v and hold at 18v so we are getting a sluggish opening on the 6.7 injectors causing a rough start.
Dumped my 07 3500 6.7 after just one year. Couldn't keep it out of Grapevine DCJ service dept. Every 3 mo. It was a check engine light and Dodge refused to keep fixing. The tech said afterwards we aren't allowed to tell you this but hauling 1K in the bed and you would have never had an issue. Great after losing 20K for a lemon. Bought a 20 yr old VW still driving today. Mechanical fuel injection is awesome.
I have my 5.9 24v, for 14 years, only had to change the water pump, belt tensioner , fly wheel sensor, clutch and belt few times. Now is in his 494,000 km, at is still purring like kitten. With Lucas oil, engine running more quite!
5.9 beat motor ever for pick ups bomb proof enough power for what ya need no need to be doing 80 hauling 25k but the best thing I like about them especially the old 24v's an 12v's is that old school rig sound cannot beat it

The g56 6 speed manual transmission is probably more reliable but not as much fun on the street. Like said in this video the 5.9 is more reliable but has some disadvantages too.

I work out of livonia for u.p.
Its all about the mechanical 12 Valve 5.9 man. A true LEGEND.
Definitely the most reliable cummins
Bingo
I'll take a deleted 6.7 anyday so I can actually pass someone with a load lol. There plenty of 6.7s out there with a million miles
@@rickshiandmoku4128 Sure there are, but we're talking about less electrical junk to go wrong
@Josiah Juan Get outta here fuck
Simply put...the 6.7 was needed to achieve more power but still meet the more and more stringent emission requirements than the 5.9 could. The 5.9 is still the dominate engine in the performance world.
Not so much...
Yeah, no.
Crazystuffyousee a few 5.9 did come with egr to meet California emissions
The 5.9 does well in the performance world but the big thing for performance cummins guys is a 6.4 cummins. Alot of racers and sled pullers use a 6.4 these days and yes I mean 6.4, not 6.7.
Emissions what's that.....it's all long gone
This is a joke of a comparison. Comparing pre emissions to post emissions is apples and oranges.... and lets face it the old 5.9 12 valve that is quickly eliminated from comparison here is the only one of the engines that can get 25-30 mpg and run a million miles... mainly due to... yup NO EMISSIONS, and mechanical everything.
The first 24v with the VP 44 set up were good too, but still not like the old 12v
Cp3 5.9s are just as reliable and can get just as good if not better fuel mileage than the ve44 or p7100 12 valves.
@@Redsfanatic32 I've owed all three and my dad's 5.9 common rail, gets 17mpg with a 6 speed and 3.55, his 99 vp44 24v 5.9 got 18.5-19mpg with a 5 spd and 4.10 gears, his 95 12v 5.9 with an auto gets 19-20 with 3.55, and my 96 with 12v 5.9 gets anywhere from 20-25 with a 5 speed and 4.10 gears sitting at 400k miles, I got 20 pulling an 18k lb trackloader
The 5.9 24V has several trucks in the million mile club as well. Mine with an eco tune and 6 speed manual would get 22-25mpg.
@@chazlewis900 I will agree the 5.9CR is just reliable but fuel mileage is no comparison. I own an 06 5.9 six speed and 3.73 rear I only get 15 empty. My brother has a 97 12V 5 speed with 3.73 rear and he get 28 empty.

5.9 cummins better
Being a former diesel mechanic I love my 5.9 24v because it is so simple. With the NV4500 trans it makes all the power I will ever need and no repairs after 20 years .The only weak link is the lift pump starving the VP44 injection pump. A good fuel pressure gauge and keeping the filter changed is so important. Unless I wreck it it will be the last truck I ever own.
My father in laws, with a manual struggles a bit more pulling my 43 foot fifth wheel than my 6.7
I had a 97 12V that I shouldn't have sold. They don't make half the power of a modern diesel, but they were reliable.
Yeah. I love mine too. Bought it new in '98, but it is rusting a lot. I have put lots of upgrades on it and I am sure it will last many more decades.
@Bill House Hey what type of lift pump you recommend changing it out with?
just picked up a 2000 5.9 with 60k miles and an allison tranny for 900 bucks, everyone tells me its a great score (i just need the turbo).
My wife and I are full time musicians and full time in our 26 foot travel trailer (30' overall). We pull it with our 2007 3500 4X4 with a fully enclosed fiberglass CargoBody cabover work van style camper. We sought out the last 5.9 (early 2007) for it's better mileage. With the cabover semi-empty (around 700 lbs) at 55 mph on level freeway, we got 25.5 mpg. Now that the camper is full of tools, and pulling the trailer (8,000 lbs), were averaging just shy of 16 mpg, which is where the 5.9 really shines, especially now that diesel is so expensive!
Had to stop the video could not look at those "trucks" anymore
Trailer Queens, spewing soot all over the place, giving Diesel a bad name! Kinda like gun ownership!!
The trucks shown are atrocious.
read your comment before seeing the video, scrolled through the video and saw them...... saved me 7 mins of my life. Thanks Jacob.
They are trucks
I thinks it's just the wheels that ruin it.everything else just makes it look clean. The only impractical things seem to be those goofy wheels
Went from a 6.7 to a 5.9. I tow aprox 70,000 a year. Don't want to up set 5.9 folks, but for my need I've found 6.7 to work for me better. My 2010 6.7 provided me with 210,000 miles in that stretch I replaced 2 water pumps 1 alternator. All other repairs were not done on the power train. The truck I'm currently piloting is a 5.9. It works ok, but I have had to adjust my trip times as I'm slowed more often than in the past. I also have a hard time maintaining an exhaust gas temp that will not damage the truck. Learning to drive with new limits is I guess a personal problem to get past. The up side to this new, to me 5.9 is the fuel mileage. My new 5.9 gets almost 50% better mileage. That is the main reason I'm keeping it.
My 6.7 gets 21 Mpg at 85mph. 16 to 18 towing my 15k camper. You have to emission delete.
@@mrrod3004 I've worn through another truck since I wrote this. I've got a 2011 now. I'll try your suggestion.

5.9 24v with p7100 most power and reliability for ever
Not bad, but you do complicate the issue with 12 more valves. Not to mention the added cost for the conversion. However it is a great choice when compared to any of the computer run machines.
Well you mention deleting things on new trucks and talk about adding things like new turbos so what would be best is to get a junk yard 24v cummins then converted p7100 this way you don't have to reprogram ecu's there's no way the ecu can change mechanical pump
Im putting my 182k 02 24v in my 06 megacab with that configuration when the motor thats in it goes its got some time left though its only got 230k right now
That's like comparing the 7.3 and 6.7 Powerstroke
It all depends on what you want in power
In both cases the 6.7 is superior
It does not reduce reliability, it removes all reliability as 6.7 emission systems will fail. I own both, currently 1 6.7 (have owned 2) and 4 5.9 trucks. For driveability/street both being modded the 5.9 wins period. For pure power/torque (max hp pre-loading boost drag racing/tractor pulls or 800hp or less towing) 6.7 is king, there is no substitute for displacement.
That being said, you will spend 1-3k+ a year cleaning/replacing emission systems (that are proven to not reduce emissions in real world applications, reason they are used: invest/law require to buy/use) on a street legal 6.7 as you warranty does NOT cover these systems, read it.
Now if you make the 6.7 illegal for the street by removing the egr and dpf and def systems it is the superior power plant for max hp applications and just as reliable as the 5.9. If you want to understand why the current emission systems do not work, ie do not help the environment, they reduce power when in action thus you press the accelerator further down burning more fuel..... That is why 10-15 max mpg 6.7 towing, 16-21 mpg 5.9 towing both trucks making the same horsepower. Food for thought.
The F--yards in the government fail to recognize that when it comes to diesels, choking them with emissions crap results in higher fuel burns on bigger engines and ultimately MORE EMISSIONS...
I've had and worked the heck out of both and the 5.9 is more reliable and better mpg and I think it sounds better but the 6.7 is still reliable but when you get rid of all the bull shit on it it's definitely much stronger
5.9 is a more reliable engine, more fuel efficient, however the 6.7 pulls and works so much better! I’ve owned and worked both.. as a daily, I’ll take my 06 5.9, if I’ve gotta haul heavy weights and push a lotta wind I’ll take the 6.7 hands down.
5.9L is not more fuel efficient. I have gotten 23mpg from my 2016 6.7L unloaded many times and see 21 daily commute.
Hey man, i have been watching a couple of your videos recently and just wanted to say your doing a great job. Thank you for your clarifications and knowledge on the subject, you explain things very well and i just wanted to say job well done.
I love my 2004 HO 5.9 dually. I am the original owner and am considering the new 2019 HO 6.7 but my 5.9 is part of the family and has earned her keep.
Also you have to take into consideration of the ho second gen they’re kinda rare but mine has 535000 miles on it and only been through 2 fuel. Pumps 1 starter and 1 turbo but if you’ve ever been in the ho second it’s a totally different animal
Have a 1993 D250 cummins, 180,000 miles in and still has cross hatching somehow. 20 mpg, 300 horsepower, it’s a dream to drive.
The info is great, but those trucks look about as dumb as a 250 pound 6ft5 man in skinny jeans...trucks with lil tiny wide tires LMAO! A mans truck needs mans tires urah!

5.9 sounds alot better then the 6.7 Cummins
When there stock with straight piped. But when you second gen swap the 6.7 it sounds like a deeper with the stationary turbo
I Emissions deleted my 6.7 runs a lot better. That the Grandaddy 5.9 is a beast. However both of them can't compete with the 12 valve!! 😍
Believe it or not the 6.7 L Cummins 24 valve is the newer version of the 5.924 valve valve
I've own Mopar since I started driving in mid 70's. Challengers, RR's, Fury's Chargers, trucks etc. I've been away from classic auto seen for awhile now / was looking for a project. I found an unmolested bone stock (except 35's and aftermarket radio), 97, 5.9 P-pump w/5sp with easy 222,000 miles no rust CA truck. From reading the comments... I think that I made a good choice.
Thanks for the upload.
You can upgrade the 6.7 by installing the 5.9 head, injection system, and ecu. Firepunk Diesel has a video on that
While there may be some benefits to running the stock vgt turbo you will quickly find its disadvantages if you’re going for maximum power. It is actually quite inefficient with a high drive to boost pressure ratio so even if you’re running your truck basically stock you’re still better off with a relatively small fixed geometry turbo (BorgWarner S380 or S400)
There are a lot of other parts that interchange on these engines such as water pump, oil pump, camshaft, valve train, front cover, etc. The 6.7 will bolt in to a previous generation truck with no modifications.
This video mentions head gasket failure- the 5.9 head gaskets have been known to hold very high boost pressures even when using oe headbolts this is not the case with the 6.7
Both motors can make over 1,000 hp with compound turbos and larger injectors. Pretty much the only reason for Dodge to make the switch is emissions control. This increased displacement allowed them to comply will still competing with Ford on power output
Thanks for the vid. I always wanted to know the differences. Sounds like both engines are good, it just depends on personal preference/use. For me, I'm glad I have the 5.9 version for reliability as I have no need or desire to add any performance mods.
I have an '03 3500 Ram dually 4WD with the 6 speed manual I bought used in 2009 with about 55K miles on it. Almost 12 years later now, it now has a little over 135K miles on it. I only use it for travel. One year it sat for the whole year in the garage, which wound up costing me over $400 dollars to replace the Optima batteries. I now take it out once a month for a short drive, about 30 -50 miles to keep everything working.
I guess my rusty bone stock 03 with 201k miles wouldn't be allowed to be on this video.
my 03 has 407k still going strong with clean oil
One thing about the 6.7 is the rod angles which is a weak point vs the 5.9. 6.7s bend rods easily when lots of fuel is dumped at low RPM. Would be a good idea to go with forged rods if you're pushing more than 1800 ft lbs of torque on a stock 6.7 bottom end.
Thanks for the input. Just looking to tow. Think the 5.9 with no emissions is probably the way to go.
It is as long as you live somewhere that doesn't do emissions testing.
@@charlesisbell4340 5.9 had no emissions other that a catalytic converter. In 2007.5 with the move to 6.7L stricter emissions standards came in to play.

Just went over 310000 miles on my 97 12 valve still running like new
what all have you had to do to to the engine, tranny, and truck get those miles? I've got an 06 5.9 with only 143,000 miles. When will I need to replace serious parts before it's not worth keeping the truck?

As a Cummins tech I will tell you a 5.9 has it all over the 6.7. Just a 12 valve 5.9 will net you 50% more than a 6.7 and it’s all mechanical. Zero issues.

Me too,600k and counting..No DEF and still smog exempt!
Me too and it’s been free and clear since 2003🤑🥰👍🏻
12 valve for the win
Mechanical pump
6.7 with vgt is in another league towing heavy, and the 6spd at with it makes it so much better than any 5.9 truck ever dreamed of being
The 6.7 doesn't "blow head gaskets", the owners do when they push drive pressure beyond the compressor map safe efficiency range, by running super duper cool race car tuner boxes to add 300 hp
Anyone who says otherwise has never used both, the 4x4 5.9 trucks in tow mode are screaming at 65mph, while the 6.7 truck can tow in 5th or 6th and run 80 loaded to the hilt at an easy rpm, although 5th is better for it obviously
The riced out trucks at the beginning were definitely comical
The 5.9 has no emissions garbage so it will always be called the more reliable engine, but the dpf has nothing to do with the engine being reliable or not, that's a totally separate emissions system..
They're both the best engines to have ever been put in a light duty truck and probably always will be...
'97 5.9 12 valve with a "P"pump for the street & 4WD
Also need to take into account the transmission options available for both. 5.9 48re and g56 or 6.7 68rfe aisin and g56 the 48 is an awesome trans
And the mv5600
The only automatic transmission for me is the AISIN.
5.9 is EMP-proof plus more MPG.
My bugout vehicle!
Ooooh. Shiny🙄 why have 4wd if you dont want to get it dirty? And it looks so stupid when you see these mirrors in the towing position all the time. I use my truck for what it’s made for. WORKING and TOWING.
What bothers me the most is why the 5.9 litre Cummins was ever replaced by the much larger 6.7 litre Cummins? I would think that the 6.7 would be fine for a Class A motorhome, and heavier duty trucks, but for a truck like the Ram 2500 and 3500, etc., the 5.9 litre would be perfect.

Never owned one up until now my 6.7 89k miles seems to run great and I can feel the power it has.
I've owned all three models of the engine and understand each was a well thought out natural evolution of the prior ones. My 12 valve had 400K on it when I sold it and its running around yet today. My 24 valve 5.9 was just as dependable but suffered from poor quality components such as step pump and water dispersal system. My 6.7 has ran flawlessly for 188K with only minor issues with the TIPM. Cummins is in a different league than the competition so any comparison is pointless.
Problem is, everyone is on the delete train. You don't need to delete the emissions systems.... Then, when they have problems with their engine, they suprised pikachu and blame it on the emissions system, creating a false narrative. The engine was designed to run with the equipment it has. Not run with a S400 turbo, deleted egr system, dpf, and 200 HP injection map in the ECM.
2006 5.9 is a great platform for those who want great reliability and the ability to make great power without hurting the pockets; G56 manual trans is even more desirable.

The 2003-2007 actually does have egr. It has in cylinder EGR via the camshaft. The lobe separation anges are closer than on the pre 2003. 98degrees vs 106degrees I believe. Closes exhaust valve a little early to trap exhaust gas.
SlimJim,
Hopefully you will see this question... or anyone else who knows... tia for your reply.
Will an older design cam eliminate the IN CYLINDER EGR ???...
@@RJ-sr5dv Hey buddy. From my understanding, having the vp44 24 valve 98.5 to 2002 camshaft is the best stock camshaft cummins ever put into the 5.9. In short answer, yes, a cam upgrade will eliminate most if not all of the cylinder egr but it should be noted that cummins also had other variables in the mix to achieve in cylinder egr, and to be emissions compliant, such as the smaller turbine housings on the he341 and he351 turbochargers as well as different emissions friendly ecm programming and I'm sure that the piston bowl shapes, injector spray angles, injection events (which are different from 2003-2004.5 to 2005-2007) are a factor as well. If you do a cam swap, it should take care of most of it but I would do custom tuning too from a place that has tested the tunes on a dyno with that cam in a common rail engine and with close to the setup that you will have. Hope this helps brother!
Slim Jim --
Thanks for that detailed reply.. Very informative
Luck me I have both now In My garage. The 2nd gen (95) 2500 complete mods on the engine and runs around 350 hp. It sits for now since I broke the input shaft in the transmission ( I have a Billet triple disk torque converter) too much power applied to the Billet shaft ? I don't know but will find out soon. The 5.9 is just plain fun to drive. I drag race a 6.7 a stop light ( really really dumb couldn't help myself) he beat me off the line but once the triple disk lock in I had him. I never done that before and won't again but what a rush for 65 year old guy.
I install new 4 exhaust. When started it for the first time my wife came out house and said it sounded like a big rig. That made my day.
I just bought a 3500 6.7.for towing the 5th wheel the 6.7 has the 5.9 beat for low end power and the exhaust brake and just plain comfort of driving . I bought the 5.9 new and may sell it one day but It would be like parting with a good friend. I know that sound really lame. But it is what it is.
All these trucks have ghey offset wheels.... wtf.......
My 2009 6.7 was a pig until i deleted everything... it then became a truck! Never another problem and it has 450,000 kms. My 5.9 has 450 k as well an it runs even more reliable. The 2 huge problems i have with the 5.9 compared to the 6.7 are lower power and the POS 48RE compared to the 68...I'm actually thinking about a CA conversions Allison conversion... so expensive though.

Oh an I almost forgot P pump baby!!!
1966cambo Yep, that’s the best combination ever in the dodge. I’ve got a 2001 with the six speed, almost rebuilt it to a p-pump 24 valve, but thought why not just get a 12 valve.

@@Dustrunnersauto the 400hp with CGI block I believe no longer has siamese cylinders. Siamese cylinders result in bores that can go out of round and are undesirable for that reason.
@@Dustrunnersauto the vg and vq 30 Nissan are some damn fine v6 engines!
Actually there is no passage between 1 and 2 cylinders (or any of the others).
If everyone here can image lining up 6 coke cans in a row. The siamese cylinders are joined like that. There are provisions for improved flow as close as they can get so that there are no cooling issues between the cylinders.
The rest is basically the same as previous years with coolant flowing around the cylinders on each side. Coolant can also flow from side to side at the front and rear of the block.
Siamese cylinders actually add a great deal of integrity and rigidity to the engine block.

I have a modified 6.7 and two stock 12 valves. I have not drove a truck that makes more power then my 6.7, but it was very expensive to buy and build. Both 12 valve trucks are very reliable other then transmission issues. I don't think you could build a 5.9 to a 6.7 potental, but the 5.9 is a very reliable engine, especially the 12 valve. The second gen 24 valve VP44 5.9 engines make good power but suffer fuel pump issues (they can be fixed though). The third gen 5.9 common rail engines make good power, they are reliable, and they can be built to make awsome power. They can give a 6.7 a really good run for its money, but when comparing apples to apples the 6.7 will out pull the 5.9.
Jeremy Smith what if you just want a daily driver and towing a max of 14,000 lbs a few times a year and go off-road a few times a month? Please tell me 12v 5.9 lol
Cummins ain’t the problem dodge is rust issues and just a junk trunk no lie
Ohio Till I die I think if ford put the Cummins in factory I would have a Ford I’ve had a good bit of issues out of the electronics on the truck itself
Ohio Till I die lol everything rusts in the north.
I’ve got a little over 375,000 miles on my 98 12 valve 2500 4x4. Replaced the starter 4 times, alternator twice, transmission twice, clutch, flywheel etc, once, but it made it to 350,000 miles though. Several sets of tires and brake pads. 2-3 sets of batteries. It’s never left me stranded (knock on wood). Truly a truck for the zombie apocalypse. Ha! Lol!
This video should be titled “The difference between 5.9 and 6.7 Cummins”.
Everyone needs to use Lucas dpf deep clean, it works!
I own 95 12 valve 5.9 stick
Also own 08 6.7 450 auto deleted
My fav is the 5.9 virtually bulletproof ... although having great issues maintaining the body
I can't help but cringe at the footage of those brodozer SEMA trucks. I bet some of them even got blue tooth driveshafts
@ 1:00 "omitting the 12v 🤔
I've heard enough. I'm out.
6BT_ Str86 kbye
Yah forget about the engine that put Cummings on the map for pickup truck moters. I own a 12 valve and wouldn't trade it for one of those newer pieces os
I just bought both lol got a 89 5.9 and love it all around I bought a 2012 brand new and love the power the 89 is stock the 6.7 is deleted and tuned and I have put over 200k on the 6.7 and pulled a lot of heavy heavy things and I don’t treat her nice and not a single break you must build the truck for the task your using it for to get the best truck
How is EGR an advancement?
It’s not. It is only an advancement from a cleaner air standpoint
I think the 5.9 is a lot better, they are more reliable, and will last longer since they don't got all the emissions crap, plus they are making the newer diesels even quieter, like who likes a quiet diesel, diesels are better loud
Hell yeah That's why I got two truck boat truck
So 6.7 has a million failure points the 5.9 didn't. Oh and uses way more fuel.
I have a 2nd gen 24v and a 3rd gen megacab they are both rock solid and i know many people with 6.7 that that love theirs and are rock solid i like them both and im getting a 2012 6.7 megacab because all those ive ever been in have been amazing
Modern pickup diesel engines sound lame. I remember listening to a stock 6.7L Powerstroke once & I couldn’t tell if it was a Powerstroke or a 6.2L Boss. It’s so muffled u can’t tell the difference
Honestly. I think all turbo Diesel engines are pretty amazing. They each have their flaws, but all can be made “bulletproof” without a whole lot of money. I have a 2011 F250 with the 6.7 diesel. I’ve done a few things to prevent failure and it’s been nothing but outstanding work truck and fast. I love the Cummins and duramax seem great too, Allison transmissions are always nice. But a lot comes down to maintenance. Diesel is a different beast. Myself, I like to drain my fuel filter every so often and replace them bout every 3 oil changes. Most people won’t and bad things happen
Cant rat on a well kept diesel of any breed
Why you drain it and change it so often?
@@braveheart2785 well. I believe I read that in a manual somewhere to change them every 15,000 miles, so 3 oil changes for me. I learned that for a Diesel engine the fuel system is a huge part, expensive, and the fuel pump and glow plugs rely on clean diesel for lubrication. And the fuel filters are cheap too. 1 fuel filter, 1 fuel filter/water separator.
All 3 (includes 12 valve) are winners. 12 valve for complete reliability. 6.7 for the ultimate power. I've got the common rail 5.9, which i'll be keeping for quite a while (the non-emission reliability). One item NOT mentioned is that the 5.9s are getting old. the newest being 14 years old now (mine :-). A 12 valve would make an awesome commuter, while a 6.7 dually is going to be your mass hauler. I.E. depends on your use. In the end, get a Cummins!
I love my 93 dodge d350 5.9L v12 Cummins
I'll take my 01 24 valve over any 6.7. Not even a comparison IMO.
Hands down the 5.9 I have an 07 with 445000 miles and all it’s had is a 2 clutches and 1 transmission and I use it daily for cross country towing
Yessir towing is the point of the cummins, people joke on my grandfathers 24 valve thats been passed down to me but i find it funny that these kids have tow mirrors on their trucks and ridiculouse rims and tires and they aint even using it for what its meant for. So what i cant roll coal, i can tow a damn church.
It’s like you went out of your way to find every crap-tastic truck possible wtf ?
you have the injector firing voltage backwards. We are working through this issue trying to run the more reliable 6.7 injector in a 5.9 truck running the 5.9 ecm. The 5.9 injectors fire at 18v and hold at 18v the 6.7 injectors fire at 24v and hold at 18v so we are getting a sluggish opening on the 6.7 injectors causing a rough start.
Dumped my 07 3500 6.7 after just one year. Couldn't keep it out of Grapevine DCJ service dept. Every 3 mo. It was a check engine light and Dodge refused to keep fixing. The tech said afterwards we aren't allowed to tell you this but hauling 1K in the bed and you would have never had an issue. Great after losing 20K for a lemon. Bought a 20 yr old VW still driving today. Mechanical fuel injection is awesome.
I would have rather have the 8.3 liter Cummins
Well heck, I'll have the DOHC ISX 14 thank you very much. 😂😝😂
I think I would rather have my KTA1150.
I have my 5.9 24v, for 14 years, only had to change the water pump, belt tensioner , fly wheel sensor, clutch and belt few times. Now is in his 494,000 km, at is still purring like kitten. With Lucas oil, engine running more quite!
5.9 beat motor ever for pick ups bomb proof enough power for what ya need no need to be doing 80 hauling 25k but the best thing I like about them especially the old 24v's an 12v's is that old school rig sound cannot beat it
I’ve seen million mile 5.9s
I’ve seen million mike 6.7s
Both are good when they are running. But the power of a proper 6.7 is realllll sweet
