“I Do Cars”
Another weekly dose of your catastrophic engine forensics! Every week you can find a new teardown of some abused, misused and/or poorly designed engine. I’ve got over 150 videos of failed engine teardowns on this channel.
Today’s teardown is an engine that I never thought I’d be able to get for…

What happened to gear driven cam timing…
GM Junk!
Curious if the reason that they were willing to go with a timing belt is due to lower RPMs of a diesel so less strain compared to a gas engine?
Curb stomp a water pump before throwing it out
Is it possible that regular maintenance was ignored and low oil level lead to overheating and seizing but the chain jumped before seizure?
this is the problem f the manufacture just use some good old Rotel t6 15w40 and I bet this will not happen but if you use what GM tells you to use ( New 0W-20 Motor Oil For 3.0L Duramax In Chevy/GMC 1500 Pick-ups) this is what will happen if you do anything but drive in the city and never tow anything but if you use your truck as a truck you should not use 0w20 oil
yep GM built a deasil not designed to last 500k miles go figure and if it is out of warrantee so why care
Such a stupid design. Absolute 🗑️
So stupid. they SHOULD have put a timing chain in the middle.
Eric, could you get a GM 2.0 turbo charge EcoTec?
Mmmmmmmm emulsified rod bearing
Sure it jumped! That is what caused the rod bearings to contact the crank!
You could say:"I have a piston from a piece of engineered piece of shit"!
Do you ever donate any of the blocks or bits that "might be salvageable" to automotive classes at a community college or trade school?
An electric forklift would be a great addition to your shop. zero gas smell indoor and u can start stop them 30 times a day much easier on it vs a combustion one. Ive had a cat 6000 # one since 2003 love it.
Chevy/isuzu really went out of their way to make the least reliable/least easy to work on Duramax diesel engine ever. Good job GM. Forbidden glitter everywhere.
Someone needs to take one of these engines and retrofitted into an older Chevy truck that had a 250 gas motor originally. Add some oil pumps to prime those units before you start.
Glow plugs in 2023 also… on a truck… shame on GMC. Still better than dodges v6 diesel…. Still 🤮.
140K miles, 3 oil changes, EGR the whole time.
The pistons collided with the head when the rod bearings failed.
I don't understand from the video what the cause of the problem was. Low oil? It appears that the valve timing system failed in some way but why? As a 3.0 Durmax owner myself I'd like to know that the owner neglected the oil or something like that. I'd prefer that it not be a design problem with the timing system or that blasted belt driven oil pump.
Very informative …and you make it fun. Thanks
How is that Harbor Frieght engine stand???
I love these videos !!!!!
There is no way in hell id run 0w20 in any engine. I dont give to shits what they say that is fucking stupid. If i buy one its getting switched to 10w30 minimum
If they would put the same built quality into their engines nowadays as they did on the early 2000s LS engines and the 90s v6 engines they would be doing great today
Any cracks in that oil pump belt will result in failure. And no oil pressure for any amount of time will be i complete engine Catastrophe. what a piece of crap design..so sad
It looks very well built. I think they used up all thier budget before designing the timing system
All of the timing on that engine should be gear drive
Honestly I haven't heard about alot of these failing. Hoping this was just an engine with a bad part or something stupid.
THAT MOTOR NEVER HAD AN OIL CHANGE IT WHAT HAPPENED TO IT AND IF IT DID GOD ONLY KNOWS WHAT IN HELL SLOP FOR CRAP OIL WAS PUT BAK IN IT
I'D SAY NEVER HAD
AN OIL CHANGE CAUSE I'VE SEEN IT BEFOR
IT'S A NO BRAINER
MOUNT THE BUGGER FROM THE SIDE OF THE BLOK
Italian junk engine
Here’s a shocker for you. China builds more Diesel engines than anywhere in the world. The have millions of farm tractors that are one or two cylinders. Kubota builds a lot of them. Most all that is ever offered here in the “free” USA is a way to take what you do, what you earn, what you buy, what you build, where you live and the control of the water you drink and the “health care” you pay for. Health care here is systematic sickness management, no cures, no universal help. Pay up bud!
Sell those pistons to Disney fans. They'll buy anything that looks like Mickey.
It's planned failure, not planned obsolescence
Have to drop the trans at 150K…for the Kevlar belt…crap design
Would not trust a part in that engine b4 damage or after!
I have one of these. Yes it burns a little oil. Apparently this owner went a long time without checking, ran it dry and poof.
But the engine build quality looks amazing!
27:25 Normally what happens when Overhead cams get out of timing ?
Let’s be honest Techs, THIS IS PURELY a POS coming from GM! I CRINGED watching you pull this rushed out the door POS gm product ALL IN THE NAME OF Greed and PROFIT! GM had KNOWN COLD WEATHER STARTING PROBLEMS right out the doors with this POS! This is JUST the start of gm’s 3L duramax diesel PROBLEMS!!! !! Right DURABLE diesels???? You won’t even hear all the problems with these POS gm will cover up ALL their QUALITY ISSUES so the public won’t hear about them, PURE DECEIT from a domestic manufacturer!! Just like gm’s Deceitful 5.3 Lifter problems!! FOOLS I mean customers will be throwing these POS in the garbage when they’ve figured out they’ve been TAKEN!! Your followers are TOO KIND!!! Thanks for really showing the TRUTH!!!!
17:45 What Milage is Recommended for the changing Timing Belt ? Always Chang them Before.
Change the oil when youre supposed to (go by milage not the damn dash display) and use the CORRECT oil (not 15w40) and you should be fine
I had a 2020 Silverado with this engine. Just traded it in in August with 146000 miles on it. It was making a knocking noise from the back of the engine on start up. The tech at the dealership said there’s a TSB about the oil pump belt tensioner bolts can back out and destroy the engine. Having other issues with the truck (glow plug codes, turbo leaking oil, and DEF problems) I decided to trade it in before I had to buy an engine.
145000 miles on a diesel..why am I thinking Oldsmobile 350… lol great video I need forbidden glitter on a shirt
And the truck spent a life fetching groceries. Its a damn shame. What the worlds come to, i want to wake up and it not be true. But it is
Mickey Mouse pistons: never seen anything like this.
I wonder if the original owner EVER changed the oil.
