DEFECTIVE Parts = Engine Failure 16-22 Colorado / Canyon 2.8L Duramax 

Dude your editing style of randomly cutting to you doing something COMPLETELY outta pocket never fails to crack me the hell up 😂😂 when you smacked the oil pan off I absolutely lost it. Watching your videos is so relaxing for me after a long day/week working on many of the same engines I watch you tear down, cursing you for how easy it is for you to remove certain parts since the engine is out of the vehicle LOL

Kids are in bed, wife's asleep on the sofa, and I'm watchin' Eric teardown a junk Minimax. Exciting Saturday nights. 😄

Saturday night isn't complete without a I Do Car's video 👌

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

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.

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

I'd like to see you do either a VW VR6 or W8. That would definitely be interesting!

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.

I think a tear down of an old Mitsubishi 6G72TT from a 3000GT VR4 or Dodge Stealth R/T Turbo would be cool to see.

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.

A hole like that in the piston is from a faulty injector.

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

Chucking the water pump into the woods was Mint. 👌 Quite a while back had a LLY in the shop with the same piston torched like that #7 I think, but the blocks are Hard, took some crocus cloth wrapped around a socket and sanded off the aluminum that was torched to the bore, got a donor #7 rod and piston, new bearing and ring set, put it back on the road. Ran like a champ. A stuck injector will mess them up in a hurry. You do good videos man. 👍

Depending on the year, there's about a 1 in 3 chance I either put the passenger side motor mount or the catalytic converter on that motor.

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😂

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.

That engine could be easily rebuilt, that being said you made this tear down look easy!

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.

I swear, these last few weeks, I've always been looking on youtube at the PERFECT TIME. Usually uploaded a few seconds ago, or one minute ago lol

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!!

It is obvious a LOT of techs watch this channel. I love reading the comment section as much as I enjoy watching Eric. Thanks to all of you for an amusing and educational videos. Merry Christmas to all of you

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.

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.

someone 30 years down the road is going to find a random water pump in the middle of the woods and going to wonder how in the hell it got there 😂

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.

It would be really fun to get one of the Nissan VC-Turbo variable compression engines on the channel. The crankshaft assembly should be quite something on those, very unusual. Apparently they aren't that reliable so hopefully there are some failed ones out there!

I have this motor in my 2018 GMC Savanna work van. I've had 4 GMC Van's and this one is quite comparable to the vortec 350, believe it or not.. The power band is in a different place. I run Penzoil Euro Platinum Dexos 2 oil in it. They spec Dexos 2 (which is hard to find). Also run ArchOil 6500 and 9100 in it. No problems with it to date except a failed Nox sensor. I change the oil every 5 thousand . Always use the AC Delco filters. I have to order them, not availible in my town. it doesn't burn oil. Great motor. Just take care of it, run #2 diesel and it will serve you well. 80 percent of my mileage is highway. I have no trouble getting into regen on my way home from work. Yes, you do have to get over how much the oil pressure fluctuates.. I was freaked out when I first got my new van.. The oil pressure was all over the map... Variable oil pressure pump...

The Volvo 3.2 I6 would be fun to see. Especially with the accessories and W/P being on the back of the engine.

Your outdoor shenanigans with good parts is pure gold.

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.

I really like that you tear them down the same way each time. It helps to learn all the parts.

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.

This channel randomly popped into my feed months ago and it has quickly become one of my favorite channels!!! Not only am I learning a lot about how engines work, but you’re also friggin’ hilarious. Keep up the amazing work and happy holidays!

The other day I saw a sausage delivery truck crash. It took a turn for the wurst.

I genuinely like every Saturday evening tear down. I look forward to them. I do like when you take older, more basic engines. Like 90’s LT1’s to show how far engines have come. Even small and big blocks from the 70’s and 80’s… They’re cheap…

I found your channel after a friend's Cummings boat engine ate a valve seat. Since I've been looking for a new truck, I've watched a ton of your videos as research. My old silverado 1/2 ton lasted 22 years. Seeing what your exposing on the new engines, I wish I kept it. Diesel is where I was heading but the added emission equipment seems to be the kiss of death. Thanks for all you do.

Still laughing about the way you edited the removal of the lower oil pan. Fantastic!

I have a 2018 Chevy Colorado ZR2 with the 2.8L diesel. Over a 100,000 miles now. I have run Amsoil in it since it was new and always use a diesel fuel lubricant to make sure I have no issues with the injectors. It's never been to the dealer for anything.

I have seen this kind of piston damage before, usually from a bad injector spraying raw fuel (not atomizing) but that was not on a common rail engine, other times that I saw this kind of damage the timing advance failed but it damaged all of the cylinders (mostly uniformly). Great video, and thank you for sharing!

That sir clip had some hang time! Dang! 😂

A bad injector blows a hole in the piston

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

Great tear down as always... Thank you Eric..

I have one of these and it was cool seeing it get completely broken down. Thanks for the video.

Erics bolt bin must be on point.

video just in time to eat dinner! amazing timing eric! also after seen these engines in their international form (LDV/Maxus T6 from VM motori) i can tell this only happened because the owner didnt know (probably first diesel kept this long?) you have to get your injectors checked every so often (i personally advice for whenever it needs a valve cover gasket, its cheap insurance) for leakdown/return leak. id say this engine had at least 150k miles or closer to 200k and the rearmost injectors where having a bad time too worn to meter fuel in properly resulting in that torched piston

The highlight of my Saturday evening. TY

I enjoy seeing you enjoying the tear-downs. Another fine video.

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

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.

Happy Saturday night!! Tear down time, thanks again Eric for another great video.

Another great teardown Eric. Thanks for my Saturday night entertainment.

Missing spark plugs? That's your first clue. 😂🤣😂🤣😂🤣✌❤

Every once in a while I would love to see a tear down of a good working super high mileage (close to a million miles) reliable engine, just to see the minimal wear and why they are so good.

As a LWN owner, glad to see one of these little monsters torn down. I just hope this video never becomes more relevant for me.

Future suggestion. Water pump skeet. Pull!!!

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!

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 !

thank you for your time and expertise !!

Yes! The 2.8 baby max....thanks for this one!

1st in New Zealand 🇳🇿 and southern hemisphere probably lol.love the vids look forward to them every week

I honestly think it's way more interesting doing these teardowns. Miles, what's bad, etc, dunno. But we get to find out!

I watched one of your old videos not long and noticed the absurds water pump trows and discarding, im happy they are back one the program !!

I love these video s. I would like to wish Eric, and his family and all of you out there a Merry Christmas and happy New year, From Dean here in Maryland

A cool engine to tear down would be a VW W8 or W12. Might be too rare as they haven't been made for some time.

I felt my shoulder pop when you deposited the water pump. I hope you stretched before the throw!

Watched a few videos on Volkswagen VR6 videos and they seem interesting or even a VR5 or at least thats what i think VW calls their 5 cylinder motors. Great vid as always mate 👍

sweet tear down sir this was the first time i’ve seen a hole torched in a piston

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

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

Nice demo, very informative.

By far the funniest video! Great job and keep em coming!

6:37 People ask why someone would 'delete' their diesel vehicle. This. This is why.

I am shocked that piston #4 didn't come apart in the engine....it had to be really close to doing so. I always enjoy the water pump toss lol

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.

Jason, love the videos and the practical maintenance advice. Would love to see a GM 2.0 Ecotec sometime if you are able to pick one up!

My favorite engines are the ford 300 and toyota 22re. I loved your ford 300 video but haven't seen a 22re on the channel yet. Any chance that could happen?

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'.

The simplicity of its design is impressive.

I look forward to these videos sooo much

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.

Look for a Volvo i5 please

Love watching your videos!

Great video Sir! Cheers from Orange County, CA - USA!!

He went and got that water pump out of the woods, I bet. Not his nature to leave it out there 😊

I think I'm the first.... I love the videos keep up the good work

Definitely need to see a before/after video on the Head going through the parts washer.

A always, love your videos! Thank you.

Good evening Eric. Time for a Duramax breakdown. What destruction are we in store for tonight?

Not supprised at all on this engine, total pile

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

The cuts to you doing something ridiculous with the “reusable” parts like the water pump makes these videos even more entertaining to watch

As always a cool teardown brother.

Pure awesomeness like always !

Great job on this video👊🏻

The head gasket, timing system and water pump jump cuts kill me, thank you for the laughs.

I love the comment you made when looking at fuel lines: "there's stuff and things!" I may have made similar comments, on more than one occasion. 🤣

that water pump dismissal was excellent sir

Hey man. I’ve been enjoying your tear downs a great deal, thank you for producing them. You should try to do a VW VR6. 12v, 24v, 3.2 or a 3.6. I think it would make a great one 👍🏼

Love the content, keep it going! greetings from argentina
