Chevy 2500 6.6 Duramax Diesel (L5P) **HEAVY MECHANIC Review** | Is It a GOOD Engine ??

[@jimdandy7772]

Buying a used 2021 GMC 2500 Denali diesel Saturday with 40,199 miles, my first GM product with a diesel motor in it, I’ve had a ford with a 6.7 diesel logged in 170, 000 plus, a 2000 Ram with over 300k, and now my first GM diesel I watch your videos and respect your opinion, very well explained

[@Slowhand871]

I’ve been extremely pleased with my 2002 Hd Duramax 21+ years as a landscape contractor towing dump trailers , excavators using it daily in tough conditions. Outside of a warranty replacement of the injectors and two small transmission repairs one water pump and 2 idler pulley replacement . I haven’t done a thing . 320k

[@bat__bat]

Yea GM really did well with the gmt800 and it's only being revealed now that these trucks miraculously outlast Toyotas while offering themselves as a potent tool for damn near any professional. And they simultaneously make crisp, artwork-like pavement princesses for the folks that enjoy building show trucks. It's a class act from GM at a special time in history for diesels.

[@Pantelifts10]

That's not bad at all for a truck that works hard. I recently got one for my landscaping business as well and I love working with it.

[@454budman]

Sold my 2003 running with 450k on it original trans and motor other than 3 sets of injectors. Still got my 07 classic w/300k on it

​@@bat__batlong stretch to say more reliable then Toyota lmao

[@bat__bat]

@@Alexbuilt *than Toyota. Yea I've driven plenty Toyotas. The GMT800 Duramax trucks are at least as reliable as a Toyota. But Toyota doesn't make a truck that can pull 25,000 pounds. Difficult comparison. My 05 Prius is my everyday driver. Had an 02 Silverado 2500hd Duramax but I had to sell it. I'll definitely get another one as soon as I can justify it and if I have the cash. As for Toyota trucks, I have no need for a truck like that. They just can't do much. A brand new loaded Tundra barely tows as much as my abandoned 97 Ford work van with a v6. I'd rather have a car from Toyota.

[@plumber802]

I gave you a sub brother. In 2022 the DEF heater harness was upgraded to mitigate the melted connector problems. The Ford 6.7 engine bay is WAY more congested than the Duramax. BTW, I gave you guys up there in Canada a "thumbs up" for inventing Poutine.

[@davidsegaline-uj1gy]

I actually got lucky and gotten '06 where they had made all the upgrades before the emissions took over and they had to do a hole redo of the whole engine '06's are more reliable and at the time they came out but they s*** little horsepower from the factory

[@JohnSmith-ev1sm]

I like this deep dive format way better than TFL etc, even though those can be somewhat useful too. Very well done review. You may be interested to know that for 2024 GM has reworked the duramax to put out 25% more power at low rpms. I like the cummins too, but its about time somebody said "enough" to the peak torque games and focused on real world, usable towing power and fuel efficiency. I'm not pulling 25k+ pounds. I'm pulling a heavy-ish RV or whatever, and want great towing power and fuel efficiency.

[@TheGettyAdventures]

Thank you! I mean I love the TFL boys they do a great job and in their defense they aren't mechanics so this stuff comes a little easier to me. I have heard GM is cooking up something for 2024! it will be interesting where they get the power from. it's only a matter of time before Duramax, power stroke and Cummins all offer over 1,000 lb-ft of torque which is a little crazy because like you said it's all about the driving experience at the end of the day.

[@jimm2442]

Those guys at TFL recently purchased a no frills basic RAM 1/2 ton 4x4 and were showing it in a video. They had the hood open and they pointed to the rack and pinion steering and said it was the front differential and the tie rods were the half shafts. I'm not kidding find that video and watch for yourself. Are you going to take their reviews seriously?

Appreciate all the thoughts here. I have a 2015 LML ~170k miles which I converted to a CP 3 Fuel pump. Very happy with the engine, repeated DEF issues as you noted. Glad they seem to have gotten it right on the next generation. I think one of the strongest points for me on the GM diesel is the Allison Transmission, seems completely bulletproof with stock power. It shifts great 170k miles in. As a combo they work great together. Not sure about the upgrade to the 10 speed, but have not heard of a lot of problems.

[@raymundosanchez2396]

What did it run for the conversation I am in California thank u

[@bat__bat]

You make a good point about the Allison. Dodge fans can't shut up about the Cummins engine quality, and I agree it is a legendary engine. But the entire package around the engine is trash. Duramax/Allison on a gmt800 is like almost too good to be true. And the LB7 ousted the 5.9 Cummins far as I'm concerned because the fueling system on the duramax is a common rail, direct injection system. That's equivalent to saying the Duramax uses fuel injection, while the 5.9 Cummins uses a carburetor. There is no real comparison. Fuel injection tech blasted carburetors out the water and continues developing today (have a look at the 3.0 liter dmax). The Duramax common rail has gone largely unchanged since its inception over 22 years ago, and Cummins and Ford eventually adopted common rail too. They knew if we can't beat em we better join em 😂 🛻💨

From what I understand Ram is upping their encryption on their ECM's now. So deleting might not be less expensive anymore. I have owned 3 different Cummins... 04.5, 07.5, and a 15. I liked my 15 other than those 3.42 gears. They were awful towing. A shift towing my camper up a hill and you would swear the transmission and driveshaft would be left there. I ended switching to a '18 L5P. I am still loving this truck. It tows my camper so much better. In fact I now tow tandem with a SxS behind our tow hauler camper. There is no way I would have done that in my '15 Ram. Maybe my older Ram's since they had 3.73's, but the brakes probably wouldn't be happy. Biggest thing with the Duramax vs the Cummins is acceleration especially towing. It was down right scary trying to pass on a 2 lane road. The L5P just gets up and goes. I have been known to never own a vehicle for very long... 3 years max. I am almost on year 5 with this truck and have 0 plans to switch out.

It's up to us as owners to remove that cap(water drain) To let water Run freely.

I own and operate a hot shot trucking company I've tried the ram cumapart cummins and the Ford rebuilt international power stroke as for money spent in repair costs and to keep the trucks running making money you can't beat the dirtymax duramax Allison combo my trucks get traded out at 400,000 miles plus they pull trailers there whole life. As for cost per mile to operate costs less per mile to operate then the cummins or powerstroke. When you use these trucks to operate a business you keep up with cost of truck and the cost per mile to operate that said truck.

FORD did NOT start doing that till 2023. I have ALWAYS owned FORD Pickup's. But this 20 year trade, looked hard at Cummins, it was the Miles on NEW used Dodges. On my Ford's always a GASSER engine. The 2000 had the V-10. Rented a 5 Yard Dump and went up a hill with that V-10 in F-600 So,so SLOW. I completely understand why FORD did this big Gasser in Fleet trucks, it was for emissions on Propane conversation. What a huge difference pulling my 7000 pound boat, with the two different brands. One being a F-250 and the other my new baby, the 3500 Silverado I have always been a FORD truck guy my whole life.

GM ran the CP4 for years and Cummins is currently using it. It definitely sucks if it fails but this is another case of internet hysteria. But just for safety sake you can install a bypass kit.

I’ve owned diesels all my life and have a 2022 AT4 and best fuel mileage I’ve ever had hands down!

[@Mr.frag-out]

Lml owner since 2015 not one problem completely stock.

[@chood45]

The MAP sensor wasn’t setting a code because it’s designed to run like that. If It was a real issue, don’t you think GM would have moved it after 5 years of production? GM doesn’t even recommend cleaning them. You’re more likely to damage the sensor by cleaning it.

[@kevinwyncoop633]

MaxMileage from Pittsburg Power will solve the emissions issues. Give them a call and just add some to your tank every time you fuel

[@dieselmutt8865]

I'm not convinced that going to a Borg Warner turbo over a Holset is an improvement. Holset's sliding collar VG is an effective but considerably simpler design than other brands multi-vain VG's. Holset makes electric VG's for semi trucks so you would think they could have supplied that to this application.

[@daveyjones369]

Holset are hands down better than Borgworner.

[@noahenglert]

the fact that you put a power stroke in front of duramax is honestly astounding power strokes are well known to blown themselves up

[@Scruffynerd]

Great video very informative. My 2015 lml had the fuel pump take a nose dive last week, and next week I pick up a 2021 l5p.

[@JROC734]

One way you can fix the MAP sensor issue is to delete the EGR valve. 🤔👍

[@Anthonymahon]

I did mine today on my 2020 duramax after watching this video last night and mine looked the same after 77,000 miles

[@mattreb5748]

I had a deleted 2011 lml Duramax with a fass 150 lift pump. It was practically flawless untill I sold it with 190k. Great truck in my opinion. That being said I know own a powerstroke becouse of how easy it was to delete. L5p is sorta stuck with factory running gear

[@Thatdudemanguy14]

You won't go wrong relying on an L5P coupled with the Allison trans.

[@VincentTactical]

I know a guy who owns a new Cummins and he can’t go from drive to park without stopping in Neutral first without hearing a loud clunk. I don’t mean while moving, I mean while stopped. The Ram diesel mechanic told him it’s because it has an aluminum drive shaft and that’s normal. I pointed over to my aluminum drive shaft on my duramax and said that’s not true for me. There are transmission issues on the Cummins that I could not live with.

[@IRQ1Conflict]

My 2017 LP5 has 70,000 kms on it. Haven't had any issues with it save for a burnt out coil that was replaced under warranty. I wasn't aware of the MAP sensor issue. I'll have to clean that. Thanks!

[@rp1645]

Also I saw you had trouble with the under HOOD release ( kind of flimsy) lever. I found the SWEET spot on mine, now I can get my Fingers on the latch every time.

[@michaelmeyers1827]

I had 1 problem with my Cummings I had a bad oil leak it cost me 4700 dollars it was. Tming chain cover 0:13

[@LSDdreams808]

My buddy has a 2020 gmc Denali with the duramax i will say its sharp looking truck an more than enough power for your towing needs.

[@TheHortond]

I use some 2 stroke oil in every tank for old engines like my 1995 6.5 TD. Seems to lube the fuel system and injectors well since they took sulfur out to kill old engines.

[@donoberley3582]

Hello just subscribed, can you comment if you recommend diesel fuel additives.I own a 2004 ram 3500 with 200.000 Kim’s . The trucks only job is to haul an rv. Great content !

[@shettlock]

Love the front end on the chev HDs and sad to see them go for next model year. Shout out from shediac brother

[@TheGettyAdventures]

I was unsure at first but in person they do awesome!

[@georgiafan6618]

Glad you’re covering the things necessary to an HD truck. There is another refresh of this engine for ‘24. Can’t wait to see where GM makes changes or improvements. Love the Duramax but the powerstroke and Cumins both good too. All the trucks are good. My Bosch injectors failed on my ‘02 Duramax. Is Bosch reliable? Good overall truck. Good video 👍

[@TheGettyAdventures]

ya those early 2000's truck were known for injector issues. and yes honestly all 3 trucks right now are great units. can't go wrong with either one.

[@LSDdreams808]

​@@TheGettyAdventuresyout Chanel is amazing i like how you get into the the specs that really matter an how you break it all down .

[@TheSummit396]

The new rams are terrible. Avoid them if you can. Duramax or Power stroke are the best options

[@justinbourgeois4685]

I just hit 120k miles on my 2019 hemi. Amazing truck

[@herculesinwyoming]

Explain please. My 2016 has had zero issues

[@madawaskarider2771]

I have a 2013 duramax dually 3500 and I just got it hoping I don't have a lemon seems like good truck tho

[@profjohnfrinks]

I have a 2017 Sierra 2500 All Terrain X that has been great. I had a mouse chew a wire that sent me into limp mode 😑... Other than that, I'm at 95k miles and going strong. I'm out of warranty since august, which I don't like. I may get a 2024 when they upgrade the interior, if I can swallow the price... 😵‍💫

[@TheGettyAdventures]

Yes the one thing I didn't comment on was the interior being very outdated knowing that the new interiors coming next year. but this 2022 compared to my 2022 ram is not even close my rams interior is light years ahead. but the engine in these trucks is no joke. these things seem to be reliable long last engines .

[@MrRasctwa]

i think i am a cummins guy but i still enjoy this video. good job

[@oscaralonzo27]

Excellent video! Would love to see a video like this on the current power stroke

[@ocjohnweber9698]

What are your thoughts on the S&B Map Sensor Spacer? Who makes the gold plated #4 injector connector?

[@richfarfugnuven6308]

I have the 2022 Sierra AT4 3500 Duramax and love it so far...

[@adrianbrakel333]

Love the channel and your knowledge. Can you do a video on the 2024 duramax and maybe gasser?

[@RXmerklll]

Genuinely thought bro was yelling at me for a second when he yelled at the camera to focus- sad to say I listened.

[@marketshare3969]

General motors put the DEF filler under the hood because they didn’t want people accidentally pouring DEF in the fuel supply, which as you all know, is an outrageously expensive mistake this was not popular with Duramax owners. I’ve heard of three people that made that mistake on Ford and Chrysler diesels and I do believe the repair was upwards of five K. 👍👊😎

[@2thelight]

The allison trans has always been the reason I go with GM, I tow large rv's, now with a 10 speed which I do not have I am more likely to replace with another duramax, unless you give good reason not to, ram has a 6 speed only but the straight six cummins is probably the top engine, Ford has the F-450 the same size as the light duty trucks which is huge in my mind, 19.5 wheels, sharper turning radius, 10 speed trans? I believe, more tow capacity, GMC has the new Denali Ultimate, I drive the Denali and would consider the ultimate, I don't know what the other makes have at this level. If Tesla made a truck that could tow 24k and tow it for 400 miles I would get it, but I think it might be a few years before that happens

[@brassteeth3355]

272,000 on my 15 Duramax 2500. I love it until I have to work on it.

[@ryanpointer2703]

Have you seen real world usage of the Banks MAP sensor spacer kit helping the issues with the MAP?

[@charliej.2716]

Nice job. Looking forward to part II.

[@TheGettyAdventures]

Thank you sir!

[@alanmorrison3598]

The term "under-square" is used to describe the bore:stroke ratio of any engine 9:59 configuration

[@kkbsrt8687]

Love your videos. Don't get quiet on us. Its been a while.

[@kurtvw9129]

Alex love your videos, they’ve really given me a lot of insight to the Diesel engine world. Not sure the best way to contact ya so I thought I’d leave a comment. I bought a 22 Chevy L5P last year brand new, after the third oil change I seemed to be plagued by the dreaded “typewriter” tick, I’ve read the bulletin from GM and its a bummer, just wondering if you could share some insight on this noise they claim is “normal”.

[@peterkunka2694]

I'm trying to understand the tuning part... do you mean about $5K to "de-emission" the truck and tune it to run, or $5K to bypass the computer to allow a chip and more tuning? My only experience with a diesel truck was a 2004 Dodge with the 325/600 Cummins pre-emissions. A very good vehicle then for towing a 5th wheel toy hauler, and now I'm shopping/considering options for a new rig setup. Thank you, and Merry Christmas! Pete in Arizona - KI7LIL

[@RyanChapman-em3xl]

Amazing!!! Cant wait for the next episode !! Its like waiting for Yellowstone lol but seriously Cummins power all the way

[@TheGettyAdventures]

Cummins power all day eh!

[@slocavky]

Fun fact, the L5P fuel pump and injectors from what I've seen are the same one they use on the 3.0 duramax as well. Also what is that tank by the brake booster that looks like its empty?

[@TheGettyAdventures]

Really eh?? well that 3.0 is looking like a great unit!

[@greghennecke4789]

I have a 21 Sierra AT4 w/ 3.0 and the fuel economy (which it was designed for...) is outstanding! Especially since they designed the peak torque @ 1500 rpm, common hwy cruising speeds. Glad to see 24 HDs getting more focus on fuel efficiency! Maybe GM should consider an inline 6 to replace the 6.6 DMax??

[@jaydenbankes8126]

Coolant tank looks bone dry I noticed that also

[@bassdaze]

funny thing is ive got 245k miles on my 05 LLY and never had any injector issues... none of the generations other than 01-04 lb7 had issues.... so put that in your pipe

[@rp1645]

The big thing is when you open the hood. Let that intake Water/ Separate system DRAIN. pULL off that Drain, when checking oil. It takes a second. Just let the Duramax AIR intake system DRAIN. Maybe you can show a video of taking OFF that Drain plug on top of the engine hood Just my Humble opinion, as I get lots of WATER when it rains. Not even driving my Pickup.

[@daisyvigil8810]

Thanks on the tip/info on cleaning this wow I own 2018 L5p an man mine was dirty bad only 70k miles smh

[@rigobertorosell]

Lol power stroke is as reliable as my ex! Now gotta give a lil prop to new 6.7 but hands down #1 duramax number 2 cummins for me! And always loved converted cummins with allinson swap! A killer duo.there

[@bat__bat]

8:45 I too, began thinking Duramax was number 3 of the big 3 trucks, in last place. Then I owned an 02 Duramax lb7 4x4 for a while pulling goosenecks. After educating myself A LOT, now I KNOW Duramax is and always has been #1. This isn't so much my opinion as it is objectively verifiable fact. Ignorance can become temporary when we get off our asses and research for ourselves. Thanks for hitting on a lot of good points in the vid. Let's remember though, 2001-2007 these Duramax trucks had little to no emissions, certainly no def crap. They had cp3's stock. Other than a few hiccups and one recall out the gate for lb7 Bosch injectors, these era Duramax vehicles are still out there hauling heavy and exceeding 300-400k miles with regular maintenance. They're resale values are very high as the Duramax runs just as strong at 20 years old as it did off the factory floor, stock. The whole truck, not just the engine. The aftermarket for Duramax is plentiful and can unlock massive power cheaply and safely. Cummins are great, but the dodge truck around it is like encasing a gold bar in toilet paper 🚽. The power stroke struck lucky with the Navi 7.3 in early 2000's but then they switched to straight trashcan juice until what, 2012? Ford is still getting slammed with lawsuits from that decade of fail. Ford internal emails show managerial coverups as they knew they were building dangerous trash, but sold it to the public anyway. Finally Ford has a decent engine with the 6.7, but they're still impossible to work on and the cp4 plagues them still today. Watching a $120k vehicle turn into roadkill because of its factory fuel pump YEARS after knowing it's been a problem.... screw Ford. RAM has had so many corporate changes since 2008, I don't know if the trucks are made in India, Britain, Bangladesh, or Mexico. And if you tell me they're made in USA, I got a bridge to sell you. Breakdown kits are real. You have to get the Aisin (Japanese) trans if you want the truck to last more than 10 years. The newer rams might actually be decent, but the costs are overwhelming and the tech isn't that great. Solid front axles on Ford and RAM are pointless and ruin the ride. All 3 trucks in modern day have excellent, reliable engines (if you swap the Ford fuel pump), but only after they've copied what worked on the Duramax since day 1. The L5P is a monster, tested thoroughly by Banks and put into use by our military. For cheapos like myself, I'm confident I can build and unlock an earlier Duramax into a timeless truck that'll work for me for decades still. For the ppl who don't mind spending money on a new truck, an L5P with some mods to the interior is the best bang out there. You can get the banks unit that makes your exhaust brake better, or install a real exh brake if the stock exh brake isn't enough for you. With modern HD wheels and tires capable of 4000+ pounds per rear tire, you hardly even need a dually anymore. When a $10k 02 Duramax with mods can give a $100k+ new Ford or Ram truck a run for its money, that's saying a lot for the engineers at Chevy. I'd drive the Ford 7.3 from 99-2003 modded up before I spent a dollar towards a 6.7. And the only way you're getting me in a Ram is if it's a gift or I'm a corpse.

[@bhswarrior94]

I hear ya there on the research part. I bout my 1st diesel in early 2018 and pretty much everything was an option from 94 on as long as it was within my $35k budget as a 19 year old. At the time I want the best thing I could get for my money. I did like a year and a half or more of just researching and going through the forums everyday for all of the big 3. I end up buying a 04 LB7 with 112K miles on it for $21k after being convinced by my mom of all people cause I was avoiding LB7s like the plague cause everyone except LB7 guys were going on about their issues. In the end it checked all my boxes of what I wanted and in a couple months I'll be at 5 years of ownership and couldn't be happier with it that truck will never leave my possession no matter what 3lse is bought at any point.

[@bat__bat]

@@bhswarrior94 you did great. Anyone selling their 04 Duramax for $20k knows they kept the truck clean and stock like a time capsule and the price is worth it. The only better purchase would be to use a time machine and get that 04 truck new off the lot. I'm envious. Once I save up enough cash, I'm going down the same road you did. These 01-07 gm trucks are excellent tools that are versatile for full-time work, side hustles, helping family and friends, and they're still efficient (20mpg) and comfortable enough to be your everyday driver (diesel costs notwithstanding). I bought my 02 LB7 strictly to haul dumpsters and cars for a business I started. But after using the truck for a couple weeks I became addicted and started using the truck for everyday driving. I sold the business and assets, and sold the truck too and I've been kicking myself in the ass ever since! I miss that truck. And, it wasn't even in great condition. Previous owner beat on it too. Had dents, scratches, paint issues, but no rust underneath, and no blowby from the oil cap. It was solid where it really mattered. Once I get my cash back up, I'm looking at pretty much any Duramax from 01-07 classic that's been babied. No doubt it'll be around $15-20k like yours, but that's money well spent. Not to mention these trucks look cool, sound cool, and the interiors are the best of the 3 from that era. Im a fan of that dashboard setup, the rear seat setup, and the features for the upper level trims rival what u can buy today. I'm not interested in ANY car manufacturer's navigation, infotainment bullshit, because I know I'm gonna customize that shit and add a decent sound system with a big screen anyway. I don't need hd radio, wifi, or any other crap that my phone or a tablet can already do much better. If I want backup cams, dash cams, and bed cams i can add better ones myself. For severe duty, you take the 3/4 ton truck, beef up the engine a little, EFI tune it, then add road-active springs to the rear leafs, add airbag system with an onboard compressor capable of filling the bags AND offering shop air on demand. Get hd rims and tires for the back 2 wheels, so 4000 lbs capacity per rear wheel on the stock 10,000 lbs rear axle. Add a 30k lbs gooseneck hitch and you can hotshot damn near anything up to 30k lbs just like the $80,000 new trucks can do. No def, no cats, no EGR, even reroute the pccv down a hose to the back of the truck into a hidden catch can or filtered exhaust so even that system isn't allowed to send oil or pollution back into the intake. Versatility beyond its years, grandfathered emissions, easy to use EFI sotf system. Yea I love talking about these fuckers and I miss mine badly. The LB7 is the OG. So what if the injectors go under a cover? You're not going in there often. It uses wastegate instead of variable pitch turbo... Who cares? That wastegate tech has worked great for decades, and the LB7 stock turbo is matched well for acceleration and towing. I see most expensive projects going LB7, you know the ones that people try racing with. The LB7 is a good candidate for building a race truck, a tractor pull truck, or even making into a big boy tow rig like I mentioned. The LLY has its strengths and takes kindly to bolt-on goodies, but you get a turbo that's a different animal than before and the EGR has to be pulled asap. The LBZ is everyone's favorite since it has the engineering advances over its predecessors, yet it is right before gm hit a wall with adding def and other annoying components to make the tree huggers more happy. I challenge you as I challenge myself: make that truck last your whole life. The concept of a truck is to be a timeless tool. Keeping it clean, keeping it maintained, and not letting anyone else drive it... If u live in a rust-free area, that truck should last forever.
