I've had 2 little 3.0 Duramax engines, in a 2020 and 2022 Sierra. Put 40K on the 20 before trading it in and have just under 19k on my 22. I don't have a single bad word to say about them. My next new vehicle will likely have a 3.0 also.
That’s a rare issue likely due to owner negligence. Its very important to do a proper engine break in before the 1st oil change and do your 1st oil change no later than 5k miles.
40 thousand miles? 19 thousand miles and no trouble. Let's hope so. Come back and talk to us when you have 375,000 miles on one of them like my 5.9 Cummins. Good luck.
@pcmountaindog yes, the legendary Cummins is a beast but that reliability means nothing when your Ram 2500/3500 is on a hoist getting a replacement transmission for the 2nd time in 6 months. Ask me how I know!
Great video of the LZ0, thank you for taking the time to film and walk us through everything. I'm hoping maybe I'll see this display at the Texas State Fair this October!
Damn. Awesome video. Glad I finally found it... a technical person talking about technical aspects of the engine! Considering this engine for my next truck to supplement my '16 LTZ 6.2 that I've turned into an overlander. I "want to believe" I have my doubts about the longevity of this 3.0 diesel. Especially when the 5.3's and 6.2's have proven to be pretty reliable. Mine is at 163k and is still running very well, no issues whatsoever.
You called the DPF the DEF. The DPF is the big chamber, it catches the soot from the engine. The DEF getting pumped into the exhaust before the catalyst and after the DPF which turns NOx emissions into nitrogen and water. That's it. The biggest greenhouse gas a diesel produces is NOx due to the extremely high combustion temps. Edit: Your dislike of the EGR system I find kinda funny. GM placed the EGR after the DPF specifically so it would stop the primary failure problem of diesel EGR systems, the soot buildup. Your complain't of it being overcomplicated it almost comical considering that EGR system is one of the simplest ones ever created lol.

I finally got a chance to drive a 2020 LM2 Silverado yesterday. Truck had approximately 85k miles and I LOVED it! The power delivery is instant and I hardly had to give it any gas to get it moving. It had more power and torque at half throttle than my current 5.3 at full throttle. Amazing engine and I can’t wait to get one. Not sure if it’ll be the LM2 or LZ0. Will depend on truck pricing.
My 2024 ZR2 with LZ0 gets 35% better MPG than my 2023 ZR2 with 6.2L. Diesel is $0.30/gallon cheaper than 93 Octane as of 10-1-24 in Texas. LZ0 is a great engine. No issues through 7K miles. I use 1 gallon of DEF per 1000 miles.
I miss the sound of a nice V8 but I get incredible power and mileage from my 2020 3.0. I’ve averaged 42.5 mph during one road trip and over 20 mph towing a 21 ft boat.
It’s crazy how every video talking about this engine I see the comments full of dumbasses saying stuff about the oil pump belt as if every gas engine made in the last 30 years doesn’t have a ridiculously complex and expensive timing system that will grenade the engine if it doesn’t get replaced every 100-150k. Why is it okay for a gas engine to need a major service at 150k but not a diesel? Btw I own one of these. It’s 2500 bucks at the dealer to get the belt changed. If you can’t afford that you can’t afford the vehicle the engine comes with, I promise.
Why name calling? I bet you have made a stupid mistake in your life. The world has been paying more for diesel engines due to better fuel economy and life of the engine. Pay more up front and reap savings over hundreds of thousands of miles. The cars and trucks that have chains are better. I had a Volvo diesel crater on me years ago for the effing belt. Perhaps I will run my Ecodiesel til GM decides to make their engines bulletproof.
If the government wouldn't be in the way with all the emissions these engines would get better fuel economy and cut the cost. My 2022 Duramax 6.6 with a 10 speed transmission gets worst mpg and burns DEF than my 2005 no emissions. I could get over 20 - 23 mpg on the highway in my 2005, and lucky to get 19 on my 2022.
The government didn’t get in the way of anything. They required a reduction in air pollution, because that is what the people demanded. Don’t like it, move to India they have horrible air quality.
Something isn't quite right with yours then. Had a 2020 and now a 2023 l5p and both are getting 20-25mpg on the highway with about 2500-3000 pounds of payload and use relatively little Def.
Can't wait for my LZ0! It sounds like the LM2 has been a fairly solid power plant, and it looks like GM only improved with the next gen. Hopefully increased longevtivity too
@@ElectricBlueIXthey're decent from what I read but they do have oil burning on a few. I wonder if the steel pistons was to take care of that issue tbh. Steel has less heat expansion than aluminum so it would make sense
@@codyweiler6083 no…its not an issue. My truck runs perfectly fine. I change my oil between 3,000 and 5,000 miles. During that time it will burn a quart or more of oil. A brand new engine typically does burn oil on break in.
I was intrigued until I saw the chain in the back. I originally saw this show up in Audi and Mercedes engines. Can't believe more people are adopting the application. I wanna do a cam swap in my driveway in a single afternoon.
I won't go with this LZ0 amd stay away from LM2. My 2021 had an engine replaced due to oil leaks. Engineers said poor block casting was the issue. Hopefully there were very few like mine! That being said, I enjoyed this engine as a 1/2 ton option.
Haven't seen too many. Most aluminum engine blocks are high pressure die-cast because of the precision and increase block strength but even a tiny bit of contaminants can cause porosity that leads to an engine leak.
Just bought a GMC 1500 Denali with the 3.0L LZO. Trip odometer says 927 miles, 28.4 mpg. 90% of this trip was interstate highway, 75 mph on the cruise control in 70 mph zone. Yeah, I’m happy.
You failed to point out that the steel pistons allowed them to make them more compact and smaller than the aluminum. So overall the weight of the steel pistons are still the same as the aluminums.
I've had 3 euro diesel cars, all older, and totally bulletproof (over 500k kms), but i havent had a diesel in over 15 years. I'm about to sell my 11' Tacoma (too small for the family), and the LZ0 has definitely caught my attention, specifically in a ZR2. Can anyone point out the biggest issues these engines have when they get to high mileage (+150k miles)? Also, how does the trans stack up? Thanks folks.
You called the DPF a DOC and the DOC the DEF. The first canister off the turbo is the DPF filter with is part of the aftertreatment system and the second is the DOC which is part of the SCR system. 2 separate systems.
Just found out today that my 2023 AT4 with this Duramax with only 13,000 miles has to have the entire engine replaced. Pretty pissed off. Warranty repair, but still, this sucks. Noticed a small oil leak. I took it to the dealer, and they said the front seal was leaking. They replaced the seal, but it continued to leak. Saying something is wrong with the crankshaft, preventing a proper seal, and it's cheaper to just replace the entire engine. Waiting on GM to approve the work and look for an engine to be shipped to my dealer for installation. At least 3-week job. Horrible.
Would be perfect if it wasn’t for having that belt… sure it’s supposed to last to 200k miles… but If or when you need to replace it you have to pull the whole transmission off to change it or even check it.. if they just made that a chain… boom, perfect.
A chain would require a tensioner which would increase the length of the engine which already just barely fits into the engine bay. It was a design compromise, sounds like it has not been problematic yet, time will prove out if it's going to be an issue. Too early to tell yet.
@@delorean831 According to one of the engineers who worked on the design team if they used a chain it would require a tensioner. That reason is theirs not my own.
It will be great if the government stopped their silly EPA emissions bs, so we could get better diesel engines. The DEF delete is what makes the bigger engines better

@@mattcaesar5781 When it comes to the AT4 and Z71 in the large SUVs, neither version of the Duramax fits. They are available in the other versions. But the LZ0 evidently won't be available in the large SUVs until the 2024 upgrades.
It’s going to use oil from the very beginning ,and then at 120,000 miles that stupid belt at the back of the engine is going to need replacing at around 1200 dollars . In the first generation the belt needed replacing at 100,000 miles ,for some people that comes quickly. One would think they could use a chain instead of the belt and make it last the life of the engine . So for me I’ll pass on anything GM.
So to replace the cam timing chains and that oil pump belt, which, being GM will be around 100k miles, you have to remove the entire engine? Brilliant!
It’s amazing how many gas engines require the entire timing system to be replaced every 100-150k and nobody bats an eye but a diesel needs a belt every 150k and people lose their fucking minds.
@@jellyfrosh9102 I don't have an issue with timing belt or chain replacement when it's designed to be replaceable. This engine has everything in the back of the engine driven off the crankshaft. That means getting the transmission or engine out, the flywheel off, then any covers to expose the chains/belts. Basically they designed it like those timing components won't fail, but we all know they will.
@@tigermanmccool4037 Just pulling the cab won't help. The chains and pump belt are driven from the back of the crankshaft. So you still need to remove the transmission or engine, remove the flywheel then remove any rear covers to expose the belts/chains. Why they didn't put the timing components on the front of the engine is bizarre.

Belt on the oil pump … seriously??
Get this and other diesel powered trucks at your local dealer starting at $90,000

Hello, thanks for sharing this information. Question: how can you tell (with the engine serial number) if it is an LM2 or LZ0 engine? thank
2023 and up Silverado and Sierras are LZ0 but 2023 SUV’s still have the LM2
Year of the truck and the way the Def/Turbo area looks.
they changed the location of the DOC to be closer to the turbo. so if you can see a big muffler looking part right next to the turbo youre looking at a LZ0

does izuzu make this??
These are produced by the GM Flint Engine Plant. In addition the 3.0 LM2 was originally Co- developed with OPEL back in 2018, which I find very interesting. Everyone asks me if I like my Isuzu, I politely tell them the facts.
Isuzu co developed the first duramax way back in 2001. They haven’t had anything to do with it since
all i need to know is
the oil pump drive belt replacement is ludicrous
High quality plastic that never breaks. HAHAHA! Right
Still using a belt for the oil pump why??? That’s gotta be the stupidest thing I ever seen!
I’m sure the technicians love doing that job and the customers love paying big 💰💵
YEP! So at 10 years old we have to kick out over $2 grand? By then it will be more. Or...the rest of the world finds out and the used value plummets. Or....the damn thing goes before 200k and Chevy won't fix.
@@DavidMosby$75,000 Truck $2,000 scheduled maintenance in ten years. What are yo complaining about?
@@DavidMosbyAre you worried you won't be able to save the 50 cents a day it will take to replace the belt?

Maybe you should fully understand an engine before you create content for it?
Sounds like you had a lot of "I don’t know" comments.
Just a suggestion- learn all about your subject b4 you make a video.

If its still got a rubber belt submerged in oil to drive the oil pump, stay away!! Possibly one of the dumbest things chevys ever done.

Belt driven oil pump is terrible, doesn't last 150kmi , and very costly to repair !

All I know is that I can't get one in the 2024 Yukon or Tahoe, especially the AT4 and Z71.
You can get it in the Yukon or Tahoe just not the Z71 or AT4 package
@@454budman I don't think they are releasing it to the large SUVs until 2024. And they haven't shown any interest in redesigning the AT4 or Z71 front ends to accept the diesel - which is a shame. It would check off a lot of boxes for me.
@@ktpinnacle are you talking about the LZ0 or lm2 because theyve had them in the suv. I looked at them bc my brother has a sierra with it and I like it, but with my wife driving a 6.2l would be less maintenance and more fun to drive to get groceries
@@mattcaesar5781 When it comes to the AT4 and Z71 in the large SUVs, neither version of the Duramax fits. They are available in the other versions. But the LZ0 evidently won't be available in the large SUVs until the 2024 upgrades.
I test drove a Serria AT4 with a 3.0 new DuraMax last week

Too bad you gotta put all that fancy stuff on there for me just to delete it.
You do realize the 6.7L Cummins is also an inline 6 right?
I have a built 6.7 and a LZ0 they are both pulling machines.
And your point is??
Right, Cummins 6.7L inline 6 just like the big 15L inline 6 cummins motors which run 1 million miles.

It’s going to use oil from the very beginning ,and then at 120,000 miles that stupid belt at the back of the engine is going to need replacing at around 1200 dollars . In the first generation the belt needed replacing at 100,000 miles ,for some people that comes quickly. One would think they could use a chain instead of the belt and make it last the life of the engine . So for me I’ll pass on anything GM.
That belt is guaranteed for 200k miles now by GM. So stop worrying about it

DEF has nothing to do with DPF regeneration.

That stupid rubber belt is junk wouldn't buy a single one. 5 Grand to replace that rubber belt at 150-200K no thank you.
Trash! They didn't fix the biggest problem. The rubber oil pump belt. Lol insane they would do that

So to replace the cam timing chains and that oil pump belt, which, being GM will be around 100k miles, you have to remove the entire engine? Brilliant!
they pull the cab off to replace the oil pump belt , nice and expensive ...100k is the inspection of belt , belts are good for 200k they say now
It’s amazing how many gas engines require the entire timing system to be replaced every 100-150k and nobody bats an eye but a diesel needs a belt every 150k and people lose their fucking minds.
@@jellyfrosh9102 I don't have an issue with timing belt or chain replacement when it's designed to be replaceable. This engine has everything in the back of the engine driven off the crankshaft. That means getting the transmission or engine out, the flywheel off, then any covers to expose the chains/belts. Basically they designed it like those timing components won't fail, but we all know they will.
@@tigermanmccool4037 Just pulling the cab won't help. The chains and pump belt are driven from the back of the crankshaft. So you still need to remove the transmission or engine, remove the flywheel then remove any rear covers to expose the belts/chains. Why they didn't put the timing components on the front of the engine is bizarre.
@@toddstidham8374 there are tons of engines with timing components at the back of the engine
Why a belt
Because GM is trash and Mary Barra is a C U Next Thursday.
