Well, not the radiator or water pump or the other thing he mentioned.

[@stevenwright6573]

I just saw a video here on KZbin a couple day ago, that allegedly solved the oil consumption issue on the 3.0 Duramax. A guy was trying to problem solve it with an extensive look into the issue. Long story short, a GM tech from a Boston area dealership reached out. Apparently, there is a defect in a part casting over the valves. The casted seam between number 2 and 3 pistons is defective and allows oil to get into the number 2 cylinder. GM has a replacement part supposedly caste correctly that fixes the issue. I cannot confirm if this is actually the problem and that it's no longer an issue on new vehicles. I just hope so, because this motor deserves to run perfectly. In my opinion it's the best half ton motor available and fixing this issue would be huge. I don't trust a motor that burns 2 quarts every 5k. To me that's just unacceptable. I will keep an eye on this issue, hoping that this was the problem. I still want one of these someday but that issue was a deal breaker for me. I need better from a vehicle a buy. Like a quarter quart between changes.

@rj3075 thanks for saving me the time to re-find it. I want to watch it again. See if this is, in fact what fixes the issue. Only time will tell, but I hope so.

Interesting. Would make sense. I think those were the glow plugs that kept going out. Will see if the issue is fixed on the new refreshed version.

[@vanlifebiker]

If it makes you feel any better my 2023 LZ0 hasn't used a drop. I ran the stock filled oil 5000 miles & changed it with Amsoil & a stock filter. I'm 3000+ miles on the Amsoil & still haven't burned a drop. So far so good on the LZ0 & it doesn't surprise me. ALOT of things were improved to make more horsepower & torque & get better MPG.

These motors are basically the same exact motor you see in every Semi Truck driving down the road but a miniature version. A inline 6 motor is known for reliability for many decades. The LM2 was a awesome motor & the LZ0 is a LM2 on steroids. I truly believe alot of these motors will be million mile motors like alot of Semi Trucks. 💪

Robert, Thanks for this honest review. I've just purchased a 2023 Silverado 1500 Duramax, and am already loving the MPG. I had it up to 32.4 this morning on the way to work in South Florida. We bough some extra protection when making the purchase just in case, but we are (fingers crossed) looking forward to having this vehicle for at least 5 years.

[@hammer-r]

If I’m not mistaken then your old one was with the LM2 engine which had a few teething issues. One was the oil consumption. There are videos out there of oil consumption related to glow plug #2 going bad . All stems from a redesign of valve cover. Seems they took care of that on the LZ0. I have a 2023 with no oil issues unless I’m towing my 8000 lbs beast of an RV. Then it uses some. I have the exact same truck as you. Love it. Great videos. Good to know if issues that MIGHT creep up.

[@TheOregonTale]

Awesome. Yes was the LM2 and did the #2 a couple times. Will be interested to see the longevity of the new motor and the changes they made. I put miles on pretty fast and will put it through its paces quickly. -Robert

[@eronshaw3084]

My LZ0 uses no oil. The rattle is solved by squeezing the rear headrest post together to make a tighter fit. Average 26 with a 50/50 mix, but I am a little heavy footed with a max of 33.5 on a highway trip during break-in, so i was driving slow. Regens occur about once a week. Overall, very pleased with mine after they finally fixed the no audio issue that occurred randomly and frequently.

I drove around 6 million miles hauling produce long haul and I've only drove one semi that didn't use some oil. Some will used like a quart or two and stay there. I guess it was it happy spot. But I will buy a diesel any day over gas. My motorhome has a cat engine and I love it.

[@scramjet4610]

Why?

[@koriemcginnis1521]

check with dealer on warranty of the oil consumption there is a bulletin 22-NA-027, can get a DTC code related to glow plugs specifically cylinder #2. This is a known issue and they need to replace the camshaft housing baffle as there is an internal weld that is broken and allows oil to bypass the baffle and goes through the EGR System and back into the engine.

[@TheOregonTale]

[@toddbunnett640]

I have a 2020 as well and have had a bunch of stuff covered under warranty. 1. The truck had the no start/long crank issue. Dealer wouldn’t do anything because it never happened when it was there. Didn’t throw any codes. I had it on video they didn’t care. The issue seemed to resolve itself around the 30-40 km mark. 2. At 40 k and 100 k kilometres I had the charge air cooler replaced. Under warranty. One of those times the truck went into limp mode. 3. The truck does consume oil. I’d say I’d the oil meter is down around 30% you can bet I’m down at least a half a quart or more. That being said I started using Valvoline and it doesn’t burn oil. Seems the dealship oil is lower quality. 4. I’ve also had a 3-4 other random engine lights that resulted in nothing nothing being done.

[@TheOregonTale]

Interesting. The only long crank I ever had on it was when replacing the fuel filters and it was filling the system back up. I may be the odd person but I actually have a code reader they I’ve had for a long time and it’s always in my tool kit in the truck. I’ve pulled it out a few times when codes throw just to make sure not a big issue and can keep driving. Sorry had a bad experience at your dealer. -Robert

[@Drivermod_Josh]

I sell parts for this truck. The oil you are supposed to use is the dexos D 0w20 ESP. if you used the extended performance 0w20 it will burn because thats oil meant for a gas engine!

[@karlschauff7989]

The valve cover on the LM2 has a bad weld that lets oil get sucked into the intake through the breather tube and causes the engine to burn oil (as well as cause glow plug failures over time). You're correct that Mobil 1 EP is the wrong oil and it could potentially cause issues with the emissions equipment. I don't know why guys think it's a good idea to use oil formulated for gasoline engines in their diesel engines.

[@fatmuscle1]

There was another guy that found that the LM2, pre "refresh" have/had bad intake manifolds. When you mentioned replacing glow plugs, let me guess, #2, and oil consumption, my guess is that you found it to drink DEF. Those are all tied together!

[@hochhaul]

Not a bad intake manifold. A bad valve cover that allowed engine oil to leak into a ventilation tube and get sucked into the engine. Basically the PCV was causing oil consumption and damaging the glow plugs.

[@MyLifeThai371]

Thanks! It sucks that the baby duramax does not have an allison transmission like the big one that is meant to last forever. I wonder how many miles before these transmissions fail. The 1/2 ton transmissions were always rated for 150,000 miles and the 3/4 ton transmissions used to go to 280,000 miles. I was amazed at how many engine problems you had with this truck at that low of miles.

[@robertskillings864]

If your glow plugs are bad and using oil, your valve cover has a bad weld inside and oil is draining through your breather. Will use more def also. Dealer should know about this by now. Need to check numbers on the cover and see if its the bad weld ones. I know a few people that fixed this and no more burning oil,

Great review. Geez that's a lot of issues. Glad you got them under extended warranty.

[@karlschauff7989]

He apparently didn't know there was a TSB for an issue with the valve cover. The supplier had a defective plastic weld that isn't visible from the outside and it was allowing engine oil to leak into the crankcase breather, causing oil consumption. That oil gets pulled into the engine and fouls the glow plugs, which is why he had to replace so many glow plugs. He's using the wrong engine oil and that's a terrible idea with diesel engines with modern emissions equipment. The plugged EGR cooler could easily be because he had the defective valve cover and causing it to burn a kind of engine oil that isn't even supposed to be in the engine, creating excessive soot or other bad deposits.

But even when their frame had holes in it just like the previous ones they owned, they still bought another Toyota. It's similar the guys that kept buying F-150's in the early years of the 3.5 EB when they were having constant issues with cam phasers and timing chains. They'd have to replace the chains and phasers 2 or 3 times, they'd trade it in for a new F-150 and have the issue again. The majority of issues with the 8-speed have been fixed since 2019/2020 when they reformulated the transmission fluid and changed the trans cooler bypass valve design. The 10-speed has been much better as far as early issues go. There isn't a single half-ton truck that has had a transmission with zero issues. The 2nd gen Tundra had issues with the AB60. The 4th gen Tundra has had reports of transmission issues. The Ford 10-speed has had a variety of issues since it first went into production. Even the Ram's ZF transmission has had issues from time to time.

[@karlschauff7989]

@@chrispope5147 Most engines spec'd for 0w20 have bearing clearances that are selected for use with 0w20 and can be at greater risk of damage by running a heavier oil. There is a recent video on the KZbin channel Dave's Auto Center titled "The truth about oil change intervals and analysis" with Lake Speed Jr. He's a tribologist that talks in detail about why it's a really bad idea to use a heavier oil than what is specified and can increase risk of wear and damage.

[@karlschauff7989]

@@oceanventure What do you mean by that? There's a difference between Dexos and DexosD. You shouldn't use just any random 0w20 oil, Dexos or not. Some oils can have a higher sulphated ash content that will cause DPF's to become plugged. Especially if you're like this guy and driving around with a defective valve cover with a TSB out for it, causing his oil consumption and damaged glow plugs. I don't know what the ash content is of M1 EP compared to M1 ESP-X2, but if it's higher, he's causing his own future issues with his truck.

I want to love this 3.0L so bad. I feel the radiator shouldn't have gone out that soon. 17 years in automotive and I've never seen a rad go that early. They have been plastic and aluminum for a long time. The water pump shouldn't have gone yet, either. However, i think your 120k review was on the first gen 3.0L? I've heard the new one, the one you just got has fixed some of those issues. I'd love to see a review on that one. See the differences. Im torn between what im getting for a new truck in 2 years. This is a truck in my top 3. I feel all vehicles have issues and recalls. It's a matter of figuring out which ones you want to deal with. If it isn't this truck, it's one of the toyotas. Even the new tundra and tacoma has some issues. Hopefully, all 3 work the kinks out.

I"m with you. My '16 ltz 6.2 is still running strong at 164k and but I'll retire this truck to the farm/small trip useage and get a new daily driver and am considering the 3.0 in a ZR2, LTZ, or High Country. I'm not yet sold on the long term reliability of the 3.0 baby diesel. I want to love it but my instinct tells me otherwise. Given the issues with oil consumption, would be very nice to have an oil level gauge ;)

[@hochhaul]

@@freidrichnietzsche6643 The oil consumption issue with the LM2 3.0 dmax was caused by a defective valve cover with an issue with an internal baffle that was allowing engine oil to get sucked up the crankcase ventilation tube and into the engine. There's a TSB for it and a redesigned part that eliminates the issue. That defect is also what caused his glow plugs to fail since the engine oil fouled up the glowplugs. It may have played a role in his EGR issue as well, but since he was using the wrong oil for the engine, that could cause issues too.

[@howtowanderlust]

@@hochhaul Maybe I got a lemon. I had multiple upper oil pan and coolant leaks that required major repairs that were just barely covered by warranty. $24,000 the first time. The second time could have been due to bad maintenance from the dealership that fixed the oil issue.

By insight do you mean you were hoping he'd have paid for it and you could assess whether or not you should?

@@tonyread5559 I know the belt itself is the same exact part number so I'd guess you're good til 200k on the LM2 too. I think they went with 150k on the LM2 for a bit more assurance because they didn't know. Now they know so it's 200k on a motor that has more horsepower & torque & it's basically the same motor with improvements. I think driving habits make a huge difference as well. If you drive like a high school wild child everywhere than neither motor may make it 100k. If you drive it like a mature adult it could last 300k miles IMHO. 🤷‍♂️

[@hochhaul]

Most of the warranty items were due to one part that had a TSB out for it that he was unaware existed. The supplier for the valve cover had an undetected defect in a plastic weld internally that allows engine oil to get sucked up a ventilation tube and into the engine. That causes the oil consumption. This engine oil causes the glow plugs to get fouled up and fail. Had the valve cover been replaced, the oil consumption would have gone away and the glow plugs wouldn't have failed.

[@hochhaul]

The oil consumption is due to a defective valve cover that has a TSB out for it. Apparently his dealer didn't bother to check. The new valve cover fixes the oil consumption. The oil consumption also lead to his glow plug issues and the occasional emissions issues as well.

I have the same 2020 3.0 Unfortunately I haven’t had the same luck as you. To the contrary. I’m currently at 58K miles and mine has lived most of the last year at the dealership. Most of my problems have been anything and everything related to the cooling system. Leaking radiator like you’re, multiple Coolant leaks in hoses and fittings. “Replacing a $2400 radiator at 38 thousand miles isn’t acceptable” Rear breaks went to 3% last year at 40K ish miles. While the fronts are still at 70% ? What’s up with that! As of right now, my Silverado has been in the shop over 20 times and I’m about $12,000 out of pocket for repairs “not powertrain related” My Silverado is currently at the dealership waiting on GM to send a replacement Turbo. After this replacement, I’m getting rid of it. Total Lemon 🍋

Sounds like you had stuck calipers. GM has been using Akebono calipers and rotors since 2014 and as long as your slide pins aren't stuck, they should last well over 100k miles depending on how much and how heavy you tow. The rotors in particular are some of the best OEM rotors I've seen thanks to the nitrided finish they use. Several years in the rust belt and still mostly rust free.

Getting close to replace the belt on the belt driven oil pump before it pops and destroy your engine

[@edwardpate6128]

If that would happen the engine would shut itself down before that happened.

[@karlschauff7989]

The belt on the engine that "I Do Cars" tore down looked like it was in good shape for having nearly 150k miles on it. The same guy has torn down Ford 2.7 Ecoboosts with the same belt that looked terrible at 96k miles. Unburned gasoline that ends up in the engine oil breaks the belts down prematurely, but they seem to tolerate diesel fine. Funny how people rave about the reliability of Honda engines with rubber timing belts, but as soon as a belt is used to turn an oil pump that is such a light load compared to turning a valvetrain, the clowns come out to act like it's going to fail at any moment. If your oil pump belt snaps from a severe shock load, your engine was already failing before it broke. Ford's 1.0 Ecoboost belts disintegrate due to the garbage tensioner design and the gasoline degrading it. Even a chain would need to be serviced by 200k miles, which is the service interval of the belt on the LZ0 3.0 Duramax.

[@robm3357]

I have read a lot about how people really like the 3.0. And the new 3.0 is supposed to be even better (The LZO) But people pls don’t do extended oil changes on a diesel. These engines are already running oil as thin as water. And diesels tend to really mess there oil up with soot. Soot is abrasive and the last thing you want is abrasive oil in your truck.

[@hammer-r]

Yea I’d never go 10,000 miles on any oil, let alone diesel. I change mine at about 5,000. I hope that it’s a reasonable amount.

Yeah definitely going back to standard intervals with my new one. And yes the 0w20 they run in these is sure thin compared to the old 15w40. -Robert

[@hochhaul]

"These engines are already running oil as thin as water. And diesels tend to really mess there oil up with soot. Soot is abrasive and the last thing you want is abrasive oil in your truck." It may surprise you to learn that direct injection gasoline engines generate the same kind of soot that modern diesel engines do. That soot also ends up in the engine oil and is a big part of why so many modern GDI engines have issues with timing chain stretch and AFM lifter failures. The biggest issue is that people have been fooled into believing that fancy full synthetic oils are so advanced and hold up so well that you can go 7k or 10k or even 20k miles on the same oil. Full synthetic oils don't have some magical additive that can remove the find abrasive soot that GDI and diesel engines make. Oil filters can't even capture this soot. 5k miles is the absolute maximum and that's if it's almost entirely highway miles. If there are a lot of short trips, especially in the winter, it should be done well before 5k miles.

The skeleton in the closet some owners are now talking about as the mileage on these 3.0 gets toward the oil pump drive belt and the engine timing chain maintenance intervals of 150,000 miles (LM2) and 200,000 miles (LZ0). Dealerships are quoting 40 hrs. labour alone for the timing chain and 8 hrs. labour on the oil pump belt. $7,500 for this required maintenance. As these traded-in models arrive on lots beware.

who knows who you talked to or how you quoted your numbers... demon works did a break down of this on youtube...a detailed breakdown of the oil belt ... 3k repair bill max... not 7500 also if you drive 15k miles per year which is normal... you would not see this repair until almost 13.5 years of ownership (LZO)

[@redlywaxer]

You were using a regular 20,000 mile Dexos 1oil for gasoline engines? Isn't this supposed to use Dexos D 0W-20 oil, the most rare oil on the planet it seems? If it uses too much oil, would there be an issue upgrading the viscosity to 5W-30, at least in the summer months?

[@karlschauff7989]

There is a TSB for his engine involving the valve cover. The supplier of the valve cover had a bad plastic weld that isn't visible from the outside and causes engine oil to get sucked into the breather. This can eventually lead to the glow plugs getting fouled and failing. There is a redesigned part that addresses this issue and should eliminate the oil consumption. You are correct in that he's using the wrong kind of oil. NEVER use engine oil that isn't formulated for diesel engines. It has the potential to damage the emissions equipment, possible even clogging the EGR cooler.

[@hochhaul]

These engines have bearing clearances specifically selected for use with 0W20. You can unintentionally cause more wear and damage by using a heavier oil.
