[@rockymountainjazzfan1822]

The 2.8L Baby Duramax is essentially a variation on the 2.8L CRD VMMotori (Italy) diesel engine found in the 2005-2006 Jeep Liberty in the U.S. The GM version was built in Thailand. The Liberty 2.8L CRD was a pre-MY2007 engine, so it had no DPF or DEF equipment. It had EGR which was often problematic. It also had issues running smoothly with the stock computer settings because of the emission controls. Aftermarket tuning solved most of those issues. The biggest mechanical issue with the engine was the timing belt--more accurately, with people failing to replace it when it should have been replaced. (The timing belt replacement is not cheap--about $1,500 if done by an auto shop.) The 2.8L is an interference engine, so a broken timing belt in the 2.8L will usually wind up with bent or broken valves and potential piston damage. Properly maintained, the 2.8L should last for many miles. The engine is not that uncommon in Europe. It has been used in Jeep vehicles there for considerably longer than it was in the U.S. and is used in some other Europe-sold vehicles, as well. It also has been sold in an industrial and tractor engine variant in Europe and elsewhere for years. I bought a 2005 Jeep Liberty new with the 2.8L CRD engine. I still own it and drive it almost daily. I would be hesitant to buy a Colorado/Canyon equipped with the 2.8L because of the emission system-related issues, but I feel the same way with almost all 2007+ MY diesels in the U.S. Too bad--I've been around diesel engines for going on a half-century, but the current generations of emission controls have cratered their overall reliability.

[@Jimbob1969-i7s]

I don't know if it is the same engine but here in Australia I have just had the timing belt replaced 150000 kms on my 2.8l turbo diesel Colorado a holden GM product $1300aus its not a bad engine but a bit clogged in the intake needs a cleanup really trying to get away with it

[@HR-rt9nh]

Howdy, i installed an oil catch can so what goes back to the engine is bit cleaner. removes about a cups worth of water/oil/soot every oil change. I think is helping to keep the engine a tad cleaner... 120k miles on a 2017 so far engine sounds good, pulls good, and oil tests show all is well.

[@TheSmortaus]

Excellent history update on the VMMotori motor. I also had a 2005 Jeep Cherokee (Australia) not a bad little unit... but had many issues with it. I got rid of it ASAP, Then I got a Holden Colorado and sadly have an updated 2.8L VMMotori motor. to be fair, the motor has been good and no issues to date.. However the gearbox GM used sucks ...

[@davidtappe5337]

I just left an over crowded Christmas party to come home and see this. Thanks buddy!!

[@tristanoliva]

The earlier LWN engines had issues with injectors sticking open and melting pistons. Later on they updated the injectors and supposedly fixed the issue!

[@FPRESLEY1]

In theory

[@ericvanswoll4611]

It clearly has injector issues, no flame travel on the piston tops at all

[@nahrens223]

I believe all year models had a problem with extremely thin turbo compressor fins that would bend flat or break off if they were exposed to snow or ice.

[@frazzledude]

That is an excellent guess. It could be an injector that is stuck open, or maybe has a damaged tip. Either way, it was pouring unburned fuel on top of that piston. There may also have been an aggressive tune that cracked those pistons from very early injection timing.

[@tristanoliva]

@@nahrens223 yes that too!

[@Adrian-qc7ky]

As a diesel Colorado owner, I'm excited to finally see the disassembly of one of these engines 😀

[@09corvettezr1]

The balance shafts in an inline 4 cylinder are indeed timed. They spin at twice the speed of the crank, and are timed such that the counterweights are both pointed towards 6 o’clock when either pair of companion pistons (1&4 or 2&3) are at TDC, which for complicated reasons are only partially cancelled out by the opposing pair being at BDC. The balance shafts spin in opposite directions to each other to cancel out some of the other forces they create themselves. When one counterweight points towards 3 o’clock the other points to 9 o’clock and vice versa.

[@VStar1749]

There is one engine that I'll bet you have never dismantled, mainly because there would be very few in the US and the fact that they very rarely break, that is the Aussie designed and built Ford Barra 4L straight 6. Its probably the best six cylinder ever made by Ford and its now extinct! Designed and built at the Victorian Geelong plant it powered most falcons built from 2002 until it ended in 2016. Drag boys regularly extract over 1500hp (stock bottom end) out of these engines and its not unheard of for them to do over 300,000miles with regular maintenance. By the way you do a very good presentation with your vids. Going to be a different world when I see you stripping down electric motors!!

[@rmp5s]

Wow. That piston cracking like that is pretty impressive...the fact that it was still in one piece is even MORE impressive!!

[@williamjames5129]

I just sold a 16 canyon with this engine. 125k with no engine or diesel/emissions failures, but I did an emissions legal tune to reduce egr and soot ingestion to help prevent some of the issues seen here. The newer 3.0 duramax (LZ0) has the egr placed after the particulate filter, which hopefully helps as well. I knew of 2 failure modes in the engine, stuck injectors (torching a piston, likely this failure) and ironically, broken wrist pins. Thanks for the videos.

[@young11984]

What was left of the head if the combustion chamber saw enough cylinder pressure to break that 1/2” wall wrist pin?

[@Ariccio123]

I'm curious - what does the emissions legal tune do to reduce the issues?

[@williamjames5129]

@@Ariccio123 it was a green diesel engineering tune. Basically changes injection timing and runs a bit more lean (like a diesel was meant to run). Soot is a product of incomplete combustion but lean combustion produces NOx which is a pollutant. The diesel emissions fluid treats the NOx, but the manufacturer balances DEF use with the egr to control emissions. The tune makes more NOx so it used more def (which meant I refilled the tank every 4-5k miles vs 7.5k miles). A compromise I was happy with. Oh, and you get more power and better fuel economy as well.

[@williamjames5129]

@@young11984 there was a long discussion on the Colorado fans forum about this. One of the vendors obtained a failed wrist pin and sent it off for metallurgical analysis. Based on inspection it appeared that the pin had been improperly hardened by the supplier. When the vendor received the analysis back, they suddenly went radio silent, and it was suggested that perhaps GMs legal team got involved (the vendor was an engineering firm in Detroit who had some connections to GM).

[@McDubz]

​@@Ariccio123 the EGR on the LWN can be electronically opened or closed, I believe as part of the exhaust brake feature (?) so the GDE tune is able to leave it closed or partially closed more iirc

Although it carries GM’s Duramax badge, it’s actually designed and built by Fiat-owned Italian engine maker VM Motori which supplies engines to GM and other major car brands including Jeep.

[@codakreaper]

The thin metal lower pans on most GM vehicles that are glued on are considered one time use. They bend so easily and even minor deflections end up leaking. As a GM tech, I've only seen a few of those engines come in for problems. One for compression, just like that one there. Time is just a jig that bolts onto the head and a socket fits where that plug is. They can be a bear in the vehicle. 20lbs of crap in a 5lb bag. Seen more wiring chaffing on the engine harnesses more than I've changed the oil on them.

[@karlschauff7989]

Most guys are just glad GM isn't using plastic lower pans.

[@georgerenton965]

Thank you for the deep dig into the 2.8. I have one in a 2017 Canyon. I’ve always wanted to see the internals, in a non destructive manner, and definitely not on my dime. I used to work at a Cummins factory service and sale’s facility in Ontario Canada in the early to mid 70’s. Rebuilt lots of truck engines. Heat cracking on the piston crowns in NTS 350 HP engines was not uncommon. Those engine where very popular in large highway trucks pulling up to 140.000 lbs. I owned one for about 4 years, then had an NTC 400. I put over 3 million kms over 26 years in that truck. 3 in frames and an out of frame block exchange, let’s just say I learned how long it took to wear things out. As for the 2.8 I’ve got 122.000 kms on it with the only problem being the exhaust system which was covered under warranty. Good thing, the bill was 5 k. It’s a stock truck, no power enhancements. I’m happy the way it is. Pull trailers often. Grossed 12.300 lbs. good mileage loaded and empty. From your video it looks well put together. Are those Teflon skirts on the piston ? The pistons might have steel Re enforcement inside the upper piston. This would help to prevent the piston from scattering even as damaged as it is. I use Delco Dexsos 2. Change every 8K.

[@garage5125]

When i saw the torched piston and heard you talking about the wrist pin, it gave me vibes of an engine you probably don't know, the belarussian д-245 (D-245) 4.75 (sometimes more) liter four cylinder diesel engine with power from like 70 to over 150 kilowatts (roughly 90-200+hp) used in pretty much everything from belarussian tractors to small trucks and smallеr russian buses with up to 10 tons when fully loaded. Yes a 4.75 engine with 120hp is used for pulling over seven tons daily. But what i want to say is than those engines can BREAK A WRIST PIN in normal engine operation!!! But the thing is they still run for a while because the pin gets splitted longitiudally in half, so they still can hold the piston set together. No confirmed idea why, i would think its material or heat treating issue, but somehow the pin always splits like a log and not break in half like the forces would try to do so. On flip side when they are well done, they can sometimes still last suprisingly long, which is impressive for a relativly small engine pulling permanently over seven tons. It would be nice to you do a disassembly on one of those, though they are probably not in your place much. But if you do, be warned that the engine weighs like half a ton so don't even think about the small orange engine stand😂

[@akashmohan999]

Ayy! Just as I was thinking "he should do a GM 3800 v6" which my 2007 Pontiac grand prix has but then he says "finding a blown up 3800 is difficult". And yeah mine runs like new, and that's after i went hard on it when i was a teenager in high school, like flooring it when freezing cold and low on oil, going on long oil change intervals, using crappy conventional oil, letting the coolant run out multiple times, all that crap i now know you should never do. And it still starts up and runs like new today (never been repaired), no weird noises, no problems, nothing. It's treated much better today though, i was not car savvy back then. I'm Running Mobil-1 full synthetic at 7k intervals, check the dipstick regularly. Only floor it when hot.

[@kd7cwg]

Might be easier to find a 3400😂. Then again mine is running perfect at 265k. Most people don’t maintain them which is why they fail

[@life_of_riley88]

Back when us jeep guys ran the predecessor of this engine, the 2.8 CRD in our 05-06 Liberty's, we'd commonly just put a plug in the egr tube. The engine management didn't notice and the little diesels ran great. It was a nice package and was a relevant car for a long time, often returning 25-30+mpg.

@8180634 As far as the actual assembly of the engine and internals, they come to us already assembled. We just put all the accessories, coolant lines, and wiring harnesses on.

[@typrus6377]

On some heavy equipment, they are moving away from EGR and instead using additional DEF to address the NOX. So far, the oil stays cleaner for longer is the most obvious direct impact, with slight improvements to fuel useage (although the engines that had this change done also had whole new fuel systems fitted as well as head redesigns, so what all contributes to the efficiency is up for debate) We shall see if overall engine longevity improves, as is generally anticipated in the technician circles.

[@bcredeur97]

That sounds so much nicer! EGR is the worst lol

[@timewa851]

In 2019, we took a family vacation to Costa Rica, 12 people in all. The family member who planned the trip rented 2 vehicles that had 3rd row seating. The vehicles were Chevy Trail Blazers. I noticed the duramax badge on the lift gates. Being a diesel enthusiast, I popped the hood and under it was the 2.8 I4 engine. I did not know that such an engine existed. We loaded (overloaded) them up with little room to spare. Being the patriarch, I took the wheel of one of them. Our domicile that we used to blast off from was a light house on the gulf, the drive way to same was so steep, a late arrival who had rented a 2 wheel drive Toyota had to park at the bottom of the driveway. We drove these things “mercilessly” for a week, all over this mountainous country. Their performance was remarkable. They were equipped with an engine brake that nearly eliminated the use of the brakes. We never had to refuel them until they were returned. Back home I launched my investigation and learned many of the points you mentioned in your tear down. Wikipedia had a photo of a warehouse in Thailand that had a warehouse with shelves holding hundreds of these engines ready to be shipped. I was hard pressed to sight a single one in my home state of NY. I did find a couple you tube videos that were very negative but most were due to fit & finish issues as opposed to the engine. I never did find a used one to consider before they became unavailable in the early 2020s. So, all that to say, I loved finally seeing you tear one down.

I have 3.0 a VM diesel. Every time I see a diesel torn down I swear it will be my last. I gave up worrying about what diesel engine oil looks like when I drove a 7.3 Ford diesel. Change the oil, drive it three miles, check the oil and it's pitch black again.

[@Gapines23]

I put 145k on mine without issue. Now in tank fuel lift pump and the HPFP well those were another story. Finally traded her in for Hemi but 4 mile instead of 50 mile made the VM tough to get hot. Sadly in Georgia it’s about 4k less than Hemi on a trade though

[@bradhaines3142]

dont even need to drive 3 miles. just run it long enough to double check for leaks, and its black. i blame the turbos cooking the oil, though im sure the diesel itself is more of the issue

[@84gssteve]

Yea, most HUIE engines keep several quarts of oil in the high pressure oil system to fire the injectors. Not to mention another quart of residuals and oil trapped in troughs. In the end about 3 of the 12 or so quarts of oil you have in the engine after a service is old and black, hence the immediate darkness.

[@cageordie]

@@Gapines23 Mine is coming up on 229k. It cost the warranty department about $30k in work, but to me I guess it has been pretty good. Fuel economy took a major hit with the emissions reflash though. At current fuel prices I wouldn't touch a diesel for what I do. Not enough towing to justify it.

[@84gssteve]

The sensor in the bottom end is probably a crankcase pressure sensor. To treat PCV emissions going into the intake, most modern diesels have crankcase ventilation filters built into some sort of catch can. When the filter gets loaded with liquid oil/sludge, the increased crankcase pressure will be read by the sensor and trip a filter change notice or at least an SPN to guide you to that maintenance item. All that carbon in the intake is typical for heavily EGR'ed engines. Using SCR fluid to treat NoX outside the combustion chamber can help reduce EGR flow and sooting, but I'll never figure out why more brads didn't do like CAT and take the exhaust into the EGR AFTER the DPF! It would still be inert and devoid of oxygen, but more importantly there would be almost no carbon to foul things up. It's ironic that a company (CAT) who didn't want to pursue emissions compliant road engines was the only one who came up with this!

[@ZeDestructor00]

I suspect they pick it before the DPF in order to improve emissions before the the DPF gets up to full operating temperature, which lets them meet temissions just that tiny bit cheaper. As others have said, the better way (by far) is to just use more DEF and treat it in SCR instead of EGR.

[@Jakek200]

3.0L Duramax has post catalyst/DPF EGR, iirc it has a valve to select if it comes from before or after the DPF which I think is done for temperature reasons. So maybe it's starting to catch on for other companies.

[@Bpf1893]

This engine does not have a PCV filter/catch can from factory. It’s a very common mod to install one though.

[@kain0m]

Low pressure EGR comes with a host of its own Problems. Most manufacturers are moving away from Lp-Egr again, because it typically isn't worth the trouble. A little soot in the oil usually isn't a problem; graphite is a lubricant after all. The issues with low pressure EGR is icing in the intercooler, poor combustion stability in cold, increased boost temperature, etc. Fouling of the High pressure EGR System can be avoided with proper calibration of the ECU, basically the warmup phase is critical. During warmup, the soot cake that forms in the intake system needs to be saturated by condensation, so that when the exhaust gasses warm up the water boils off and breaks off chunks of soot. The issue arises when manufacturers don't know about this and focus the aarmup phase solely on emissions... It can make or break an entire engine family.

20:06 engine oil level sensor. The pressure sensor is on the oil filter housing you can see it 18:06. Fortunately, not a variable oil pump on these but they sure do run some scary oil pressure at idle. I had a 2016 Colorado with the LWN, from brand new off the lot until I traded it with about 40k on it, it would hot idle at 15-16psi. No joke. I was further curious so I pulled the engine specs from GM Service Information and sure enough the minimum allowed oil pressure hot idle is spec'd at 10psi, and a minimum of 36psi at 3800rpm. I didn't burn any oil, only issue I had was a DEF heater failure on the DEF injector line. The other thing I found wild was they allow for a maximum of 72.5psi variance in compression pressure between 2 cylinders. So if cylinder 3 made 200psi, cylinder 4 or cylinder 2 can be allowed a 72.5psi +/- difference.

My def line just went out for the second time this weekend. first time was under warranty this time it's on my own dollar.

[@chrisrobinson8937]

I'd like to see a Cadillac 500 or 472. They were pretty advanced for their time. High nickel block, external oil pump, no coolant in the intake, relatively light weight for their Era. I like old stuff too. Maybe a straight 8 Buick? Lol

[@JimMorris-g6y]

Let's see a tear down of a plain old Honda R18 engine, 2012 vintage. Shouldn't take long but it's a bullet proof engine IF taken care of. Let's see why they're good when new......then worn out or destroyed. Keep up the good work. My wife even stops what she's doing to watch an engine tear down. Unreal when she does something like that.

I did one. It was catastrophic.

[@Bigdaddyslasher]

That blow by was epic. I don't understand why manufacturers say do 10,000 mile oil changes on diesel engines.

[@genuismensa]

If it is broken it is a 2016 or earlier 2017. Ask me how I know... I had one of these. New turbo, new def system, new transmission, new tq converter, new sharkfin antenna, a complete new rear harness which meant the truck was cab and box off before 20k miles. After my truck GM wrote a TSB about the harnesses grounding out on various parts like the transmission in my case. My 2016 CCLB Colorado Z71 was a nightmare. I loved the idea of it, but it just wasn't built like a mini version of a duramax truck. It is an s10 with an Italian designed diesel made in Thailand by Isuzu lol. I can't believe that truck was 42k USD brand new in 2016! That engine was a 6,000 dollar upgrade, and only available in two trim levels at first. This one did not get frequent oil changes. They are spendy to do with all the good oil it needs and oil filter. The stealership wanted 120 bucks for a full synthetic and a tire rotation.

Hello, you should definitely teardown a GM 2.7l L3B Turbomax engine. As a 4-banger used to power full-size pickup trucks, this engine has been very controversial among mechanics and car enthusiasts.

Yeah, I don't think this is gonna be GM's best idea But hey, maybe they'll force people to upgrade to larger engines. Idk, but I agree w\ you - it's controversial & I don't see these lasting to 100k in fullsize truck applications. That's why the 5.3 was so popular. We will see tho👍🏻👌🏻🛠️🔩🔧

[@94XJ]

​@@tdotw77A turbo 2.7 has gone pretty well for Ford for almost a decade now, but it is curious that GM opted for a 4 cylinder. I've wondered why they didn't opt for a variant of the 3.0 turbo 6 Cadillac runs. They're already pretty high-torque at low RPM engines. *shrug*

No they don't rev hard. 1600 RPM @ 100 km in 6th. Max torque (500NM) at about 2000 RPM. You'll only see them cross 3000 when you're rounding up a 4 trailer road train.

[@danaitcheson9571]

Pretty common for these in this part of the world (New Zealand) to run low on oil and do damage as the engines use approx 1.5l of oil between changes. GM’s fix was a longer dipstick with new high and low marks 😂. Was surprised to see the bearings in such good shape

[@mikewilson631]

Shorter dipstick, surely? Or a longer tube.

[@danaitcheson9571]

@@mikewilson631 No, longer dipstick to reach further into the sump to allow a lower oil level before going below the low mark as they were replacing too many engines under warranty for oil use. Also the full mark was slightly higher so the amount between the 2 levels is about 1.8l instead of 1l.

[@Bowhunters6go8xz6x]

Cracked and Burned through pistons on the 2.8L Duramax are known problems of that engine supposedly caused by fuel injection issues. IMO that super thick coating of black soot would prove that out on this engine but that is IMO. Also IMO the owner wasn't doing his oil changes !

[@stevenbrowningsr1144]

Like this one as I have a '16 Canyon with the diesel. My oil gets a little color, but with 6 month oil changes it doesn't seem to get that dark. The nasty intake seemed to suggest to me that it may have been allowed to idle for long periods?

[@TestECull]

15:11 Given the timing system is designed to guarantee these things die right on command I'd suspect the pistons are not substantial enough for their jobs. Either that, or someone was feeding it a bit too many beans with a bullydog or somethin'.

2:18 We did at my workplace the other week. A Toyota 1DZ-II in a forklift. Pretty sure it grenaded and just didn't install an inspection port 'cause it only sounds like 3 cylinders are compressing now.

A bad injector blows a hole in the piston

I have a 2015 s10 chevy pickup that has this engine in it but this version has 200 hp and also 369ftp torque. And the only thing I've changed on it is the headgasket and water pump at 280.000 kilometers and now works like new. I live in south america (paraguay) and its a Brazilian model pickup its super reliable, starts in half a second every damn time. There are also lots of people here that tune these engines up to 250hp without issues, my buddy's pickup now has about 200.000 kilometers on it with the 250 hp tune and still going strong. Good little engine.

[@TestECull]

@@jellyfrosh9102 Or just never giving it the beans. Any engine will build up like that if it's never flogged. They need to get run WOT on the regular because it helps them clean themselves out.

[@OperatorPuski]

Not sure if this engine does it but typically during the regen process additional fuel is sprayed into the back cylinders to increase the heat so the filter can burn off. Ford 6.7 sprays into 7 and 8 during regens. Certainly contributing to more wear

[@justinwatts6210]

i firmly believe that if the egr system had been removed immediately this engine could probably still be on the road

[@chris3407]

I believe every automotive diesel engineer has nightmares about EGR and DPF systems.

[@8180634]

What they should have done was scavenge the EGR gas after the DPF. All that blowing the soot back into the intake is recipe for carbon build up. But then again, their goal is to get past the warranty period, and not long term. This will unfortunately hurt the brand I think.

[@Duken4evr29]

Agreed. That is why my '17 Canyon with a 2.8 got GDE emissions system intact tuned to turn off EGR electronically as soon as I could at low mileage. Doing that was a risk as it voided the warranty on an expensive vehicle that I bought new, but now my '17 is going on 80K miles so well out of it's warranty period anyway, so I guess I win 😆 The interesting thing is the oil doesn't turn black with the EGR turned off tune, you would never know it didn't come out of a gas vehicle, it's that clean. Have had zero problems with it so far. EGR is the work of the devil when it comes to diesels...

[@user-ns9ld8vv4t]

​@@Duken4evr29 GDE is an EPA snitch, who gave them his whole customer list... Including you and your truck

[@craighall6185]

I have seen this down in NZ on these engines! They are oil burners from the factory. Here in NZ they Holden (GM) Colorado of this era, pre-2017, uses injecting diesel into cylinder 4 for the DPF regen. This can if the oiling system is tired to much heat at the crown of the piston…then…boom!

[@stevenlatham4397]

When these were originally released, a 6 speed manual was supposed to be available in the lowest trim of the Canyon/Colorado. I put in an order for one and dropped an $8,000 deposit. I was warned it would be 6-8 months before delivery which I was totally fine with. 4 months into the waiting period, I get a call from the GMC dealer saying the manual option had been cancelled in the U.S, but they would upgrade me if I would take one with an Automatic. I got my money back, and am still driving the truck that I was going to trade in on that one.

[@I_Do_Cars]

With a manual, that would be a pretty cool truck.

[@jimmyaber5920]

Low oil pressure that decreases oil cooler spray cracks turbodiesel pistons. It takes 1.5 to 2 Bar to open spray inlet valve. The cooler spray is shut down to assure good hot idle speed flow for turbo. At idle piston cooling cooling isn't needed.

[@warrentinsley5490]

Look for a Volvo i5 please

[@georgepeck-g4h]

the piston cracking is from over fueling,big trucks have pyrometers so they can tell when exhaust temp is high cylinder temp is high. either what they call 'rolling coal' or go fast program.
