  • Today we're going to go on a journey and look at every Duramax engine that GM has built, from the LB7 all the way up to L5P. We're going to look at what makes each engine special, interesting, the common problems, and why GM had to continue iterating the Duramax line with new engines every few years.

    I have a 2500HD with the LBZ. This is the only diesel pickup I have ever owned, and I bought it new in 2007. It is bone stock, with about 340,000 miles on it. I have been very happy with it. No major issues, and not many minor ones. Still runs and tows great. Still gets good mileage, and doesn't burn any oil.

      I owned 6 semi's with Cummins ISX motors and while they imo outperformed the competition they were high on the maintenance side. Very high. Constant EGR failures were a big issue and I do mean constant even with reduced idle time. I retired in 19' and I am sure the new X15 has solved some of those problems. If you have a Cummins you better have deep pockets after the warranty is what my experience has taught me. Now I own a 2020 GMC AT4 with the L5P pulling my skid steer and implements and I love it. Very strong motor all stock no issues so far and it has 98000 miles on it.

    Having driven every version of the duramax except the LML, I would say that if it's my money to buy and maintain, I would just as soon have an LBZ. I can work on it, it's very reliable, any problems I might have are well known, etc. If I was suddenly given a truck allowance from work, I would have an L5P, for sure! More hp/ torque, better brakes, better frame, integrated trailer brake, basically more of everything.

      I had a 1985 High Sierra 3500 that had been factory ordered with the high output version of the 6.2. I bought it used in 1991. Before that I had a poor opinion of the 6.2 and the 5.9 Cummins was just being released in the Dodge and several friends bought them. I was allowed to take the 3500 home for the weekend to try it out and I was amazed at how much power it had compared to other 6.2’s. I bought it and had a straight dual exhaust installed with a crossover pipe right behind the transfer case. That was one sweet sound and it had a distinct loud cackle at mid RPM’s. It pulled right with the 5.9 Cummins until high gear where it couldn’t quite run with them. (Auto trans) At the time I was told by a dealer tech that they referred to my engine as the 6.2J and they were special order Good truck. I traded to a new ‘93 Dodge Cummins in 1994 and drive it for 17 years and 340k miles. Never had a single repair on that engine other than turbo and injector upgrades which were huge back then, and regular valve adjustments. Next was my current ‘09 D-Max that was deleted and and old school tuned early on. It’s a towing monster and now at $200k miles. Had its share of incremental repairs of late like thermostats, water pump, glow plugs, fuel lines, etc. but I still love it.

    Really love your videos. Getting information really helped me with my 6.4 a few years ago. I was better able to make a choice on replacing the truck or rebuilding a more reliable 6.4. I went with a rebuild with many upgrades including pistons and a full delete. It cost around 20k but has proven to be dependable and has ample power. Only downside is fuel consumption. I dont think that can be fixed. To replace my truck with something comparable to what I ended up with would have easily been over 40k. Thanks again.

    Good video. A couple correction points. The DEF is not injected before the DPF, it is injected post DPF into the SCR. It is used to break down NOX into N2 and Water. It has nothing to do with hydrocarbons or soot removal (that is the DPF). GM was really smart to add the 9th injector instead of using post injection like other post emission diesel engines.
    Also: EGR is primarily used to reduce NOX rather than reburning hydrocarbons in diesels. The way it achieves this is by reducing the combustion temperatures. GM was also pretty clever on the 3L duramax by using low pressure EGR and taking the stream downstream of the DPF/SCR. It works more effectively this way but also doesn't recycle soot into the intakes. They have pretty much resolved all of the issues that modern emission systems caused.

    The LB7, i.e. the first duramax, was debuted at 300hp/520tq. Several publications usually get that wrong, and GM wanted to be the first to crack 300hp when it debuted. GM probably knew the common rail cummins was not far behind and needed that leg up.

      I have a 2002 & 2004 LB7 that I bought new. I also had a 2001 LB7 but the truck went to the shop so often that I traded it in before it ran out of warranty (36,000 mile/ 3yr) The LB7 was not the problem.

    My father and I both bought l5p’s mine is an 18 and his is a 19. I used mine for a hotshot rig and his is a daily driver. I’ve had a ton of problems with injectors, 3 or 4 needing to be replaced and a lot of injector harness issues. All of my problems happened after putting 100k miles on the truck. The last straw for me was the one of the heads cracking between the injector and coolant passage, at around 265k miles. My dads had to have 2 injectors replaced within the first 2500 miles. And at 27,000 miles started having valve problems, every single valve on one of the heads started leaking badly and they ended up having to replace the head on that side. I’m not convinced the L5P is better than the LML. However I did crack pistons on 2 LML motors in my 2011 hotshot truck.

    The L5P is truly, undeniably the best Duramax ever! In fact, I think it's the best diesel period...it may be a few HP short of the others, but 'quality over quantity' is best in my opinion! This thing is absolutely amazing, my '18 is stock and has more power than I'll ever need (yes I do USE it) and the acceleration thanks to the Borg Warner turbo is amazing even compared to gas powered trucks (6.0, and the new 6.6 gas). Completely flawless at 63K so far, I love my L5P!
    Update: 71K, still flawless!

    Great video! What's not that well known is that the 2017-2019 L5P is technically a gen 1 and the 2020+ is a gen 2. GM doesn't mention it but Banks did a side by side comparison and the cooling was significantly improved with larger cooling fan, larger oil cooler with a better design for flow, and better turbo cooling. I believe they also dyno more power stock for stock but can't say for sure.

      Correct information on cooling systems including a separate belt for the larger fan. I believe the engines HP and Torque are the same as the gen 1 though. I wonder if they made any improvements in the injector connectors?

    2006 had LLYs and LBZs, both bolted to the 6spd Allison transmission. LLYs were first half of production and LBZs finished out the production year - verifiable via VIN. My 2006 LLY is sitting at 615k miles right now.

      The 2006 LLY is mechanically an LBZ. The engine was released before LBZ tuning was approved. Years ago you could go to the dealer to have your 2006 LLY tuned with the official LBZ tune.

    As a kid I remember my dad having a stick shift dually with a 6.5T. That truck was such a dog he lost the turbo in Oklahoma and drove the truck all the way back to South Carolina with no issues. I think the 6.5 only made like 10psi of boost. Diesels now rely heavily on their turbos (15-25psi). We've currently put 190k on a LB7 and a few on a LLY so far with the only major problems being injectors. The LLY injector harness drove me crazy. The only necessary changes were cat fuel filters on both, injectors on the LB7, and egr delete on the LLY. The LB7 truck had it's factory brakes replaced with the front hubs around 210k miles.

    A lot of people love to hate on the LB7 for the injectors, but some of the highest HP/torque trucks to hit the dyno at the Ultimate Callout Challenge have been LB7s. And once you switch to the SOC injectors over the VCO that came stock the longevity issues go away.
