The steel plate in the timing cover is likely there for noise reduction. The cover may vibrate at some harmonic frequency and the plate is there to change that frequency. The aluminum oil pans with small stamped steel lower oil pans on many new vehicles have the stamped steel lower pan there for the same reason.
"We need to see some broken stuff." No analytics required. Eric knows why we're here, to see engine parts where "some assembly" is required. Thanks for the video. When it was getting to be time for an oil change, these videos were a better reminder than the nag screens on my car.
Suggestion: pull the oil pan without turning the engine upside down. I think that would reduce the amount of fishing through the engine for piston mcknuggets.
Piston mcnuggets... I love it. You might be able to save the block with some JB weld and a few pieces of the former piston. If a blown engine from a car is carnage, would a blown engine from a truck be trucknage? Oil is over rated....
Ever since the LS engines introduction, I've never seen a single one that didn't show a little bit of copper on the cam bearings. I've rebuilt and modified quite a few of these engines, and the wear in the bearing areas are almost identical. The cam plate was a year specific item. The early styles did have 10mm bolts, and late 03 started using countersunk screws. You can use either one when going back together, because they'll interchange. The engine you're working on is a rare bird because it was only made for two years. It's too bad it's blown up though.
Can second the always checking the oil, especially in this LH6 engine. Have one in my 06 Envoy Denali, and these engines specifically are bad for low oil because of the stupid oil pan design. If its low, under acceleration all the oil rushes to the back of the pan and starves the engine because the pickup tube is at the front of the engine...Change the oil every 5K miles or 6 months on this engine! Been doing this for the last 7 years and its kept me trouble free!
I had one same year until it got crushed by a pine tree from the hurricane last year. I had over 200k miles on it. I had a guy in the trailblazer ssforum make me a cheap baffle for the oil pan in which I riveted on one side. It only cost $20. Worked out great and I didn’t have to watch my oil anymore lol
Valve or variable? I have heard it called Variable Lifter Oil Management as well for the horrible idea of DOD/AFM. This is what happens when engineers try to appease bunny huggers.
21:46 - _In Morgan Freeman's narrator voice:_ "And here we see several baby pistons seeking refuge under the skirt of their mother piston away from the harsh environment of an oil-starved engine..."
Nice teardown. I would score this as a solid 9 for carnage and a 10 for collateral damage due to migration of metal chunks from piston into intake and then into all the other cylinders. 5 bonus points are added for hole in block.
The guy with the JOKES this video! Great one liners (your son must LOVE it)! Keep it up, always fun to watch these tear downs and your channel in general…
Great video buddy. Love hearing your description of things as you pull them apart. “ Piston McNuggets”, that’s great stuff. Thanks for such entertaining videos, and again, thanks for sharing. Big Al.
Piston McNuggets... LOL. I'm not sure you mentioned this in previous videos, but there is a smell you get when cracking rod and main bearing bolts. Perhaps you could give us a heads up when you crack the bolts and the aroma is released. Sort of like smell-O -vision.
Yes indeed. What a stain on the reputation of Cadillac those things were. I think the version that Olds used in the Aurora, it was smaller like a 4.0 liter or 4.4 liter, can't remember, but even that was a lot better version than the one Caddy used.
Having had an Aurora, which sleeved the Northstar to get its 4.0-liter size (all external dimensions and points are identical, and the Aurora "hot-rod swap is to find a 4.6 and drop it in,) I read somewhere that the case material was so porous they would lose oil and grease the outside of the block just sitting there; oil would seep through the metal. A common failure, early on, at least, was head bolts pulling out of the block, taking some threads with them.
I've been in a car that has happened to. First it sounds like it's being fuelled by spanners/wrenches. Then, it sounds like the pistons are going to come through the hood before a massive explosion 😁
Stamped steel plate on the timing cover is for clearance for gen3 water pump. Gen4 water pump has more clearance for vvt. Also these trailblazer 5.3s have dipstick going to the oil pan instead of the engine block but you can drill it to accept a regular truck dipstick.
I don't know why these vids are so refreshing and entertaining!(the piston decided what the plug gap was gonna be...CLASSIC!🤣) When people talk about LS's are indestructible, it matters WHICH LS they're referring to. And AFM was an awful addition, second only to the other GM deplorably awful advent, V-8-6-4.... HOLY PISTON MCNUGGETS, Adam! 😆
You should check out the videos on the Ford Coyote engines. Especially with the flat-plane crank. Make one wonder why Ford is $278 billion in debt. Got to love those class action law-suits
You should sell the grenaded piston as a puzzle kit. Introducing the I Do Cars piston puzzle! Fun for the whole family ages 8-80! Only 39.95 at the shop. Get them while you can!
Here in this video we see the birth of the majestic baby pistons in the wild. After birthing the baby pistons, the mother piston will protect the baby pistons under her wrist pin, keeping them warm and safe until the upcoming racing season…
I had a really nice 07 Envoy Denali with the 5.3. It would literally go through a quart of oil every 500 miles. You had to keep a close eye on it or it would drain itself dry between oil changes. The DOD finally went out during a 10 hour trip to Wisconsin and it started tapping. I was so mad at the thing I literally drove it to the nearest junkyard in Kenosha and sold it for $300 on the spot. 🤣
Not sure if you answer questions. If you would. question? what is percentage difference between engine failure cause; Poor design? Poor maintenance? Great channel. Great video as usual. Carry on!
I had a regular wheelbase 08 Trailblazer with a 5.3, it would burn oil like crazy. I had the DOD deleted but the damage was done. Great SUV but the planned obsolescence was more than I could bear
I religiously watch all the engine teardown vids, however this one did not show up in my subscriber feed, for some reason. I happened to be manually browsing to the channel and found out there was a new teardown posted 12 hrs ago! If this happened to anyone else, please like this comment so Eric can see it.
Re: the hole in the pan for the diffs/axles...Some 2wds also have it. We have an 08 TB with the 5.3, 2wd and it has the hole for the axle shafts as well.
" kool aid man " had some fun with that block ! 🤣 Come on , a couple tubes of jb weld , that block will be good as new 😜 . The " malice in the combustion palace " , good one . Makes ya wonder , how fast were they going when it let go ?
16:35 Well that's new. Horsepower replaced with engine powder. 😱😢🤭🤭 26:11 Naw, ya think?! And now, the umpteenth time: CHECK YOUR FRICKIN OIL!!!! Thank you. Have a nice day. 🥴🥴🤣🤣
I have the aluminum 5.3 version of the Envoy but I have the weird one known as the XUV. I'm not looking forward to pulling the engine for a rebuild either as the front axle goes through the engine with the diff bolted to one side and the actuator to the other.
jajaja you're a comedian now - "These pistons look great.. Just don't look here" I wish we we're friends and could hangout at ur shop. thx for the laughs
As usual, great video. Looks like that poor thing was in really rough shape prior to the catastrophic piston removal and block vent port. It was really used up.
Trailblazer wasn't the only ls with a awd sump and diff mount the Holden adventura and hsv coupe 4 (awd gto) in Australia did to. it had a ls1 with an awd set-up
I have a 2005 Chevy trailblazer with a 5.3 liter V8. It has a bad rod knock on the number 6 rod. Haven't even started it for 2 years because if I am going to replace the engine I want to have a decent core. The engine ran fine before I went to Walmart. It wasn't until after they changed my oil that I learned they sucked the oil out through the dipstick tube using a small hose. That leaves all sorts of garbage in the bottom of the oil pan which gets clogged up in the oil filter which leads to exactly what you are seeing in that engine there. It usually starts with low or no oil pressure at idle and you can see that through all the bearings. Doesn't matter what you see on your dipstick, it's gonna show you have enough oil but the pump isn't going to move it.
"Malice in the combustion palace" has so many uses. Saved!

I feel like the “piston delete kit” should be up there on the mechanics joke list with the muffler bearings and blinker fluid.
I have to admit, watching these videos have prompted me to check the oil in my cars every week.
"75% is a passing grade" - that one left me rolling.
The steel plate in the timing cover is likely there for noise reduction. The cover may vibrate at some harmonic frequency and the plate is there to change that frequency. The aluminum oil pans with small stamped steel lower oil pans on many new vehicles have the stamped steel lower pan there for the same reason.
Thanks for answering that!
I like that answer: it gives a plausible explanation that could not be seen from the static teardown.
Glad I didn’t have to search the comments to long to find out why myself, I was very curious
isn't it introduce an wake spot in the block
"We need to see some broken stuff." No analytics required. Eric knows why we're here, to see engine parts where "some assembly" is required.
Thanks for the video. When it was getting to be time for an oil change, these videos were a better reminder than the nag screens on my car.
A reminder that a oil service is never a waste of money in the long run!
Your voice and humor makes your educational information very intriguing.
Lubrication 3:16. Let he who is without oil throw the first rod.
Suggestion: pull the oil pan without turning the engine upside down. I think that would reduce the amount of fishing through the engine for piston mcknuggets.
That is true
My week isn’t complete without seeing some engine carnage!
"some piston McNuggets falling out of this thing" hahaha 15:55
Some engines have temporary cylinder deactivation...the new fancy ones have permanent deactivation. It's way better.
Piston mcnuggets... I love it. You might be able to save the block with some JB weld and a few pieces of the former piston. If a blown engine from a car is carnage, would a blown engine from a truck be trucknage? Oil is over rated....
This made me laugh out loud -- thank you.
@@intensemojo Your welcome. I'll be here all week or at least until the honey do list disappears....
I actually think the former owner just installed a total loss oil system on this engine.

I heard GM northstar motors were notorious for oil consumtion. Love to see you autopsy one of those.

A common failure, early on, at least, was head bolts pulling out of the block, taking some threads with them.
I would dearly love to hear the sound made by the engine when the on-the-fly piston delete actually happens.

Oil? Is that an important component in an engine? Some people must think not! Amazing!
Same engine as in my trailblazer. Thankfully my dude Lucas Hartsel rebuilt it with DOD delete. Small cam an headers with tune drives great.

You seem to suggest this particular LS blows up, but letting ANY engine run out of oil will produce a similar result. Nothing to do with LS.

Doesn't matter what you see on your dipstick, it's gonna show you have enough oil but the pump isn't going to move it.
The fudged over hole is where an opti-spark would go.
How about a 4G15 Mitsubshi? I've had a couple of cars with that engine in them.
