This teardown is Just for the video! I knew buying it would not net any possible gains from part sales however its been a couple weeks since we've seen combustion chamber malice. This is a 3.6L GM V6, Known as the LLT. This is found in early GMC Acadia, Chevrolet Traverse, Buick Enclave, and the Saturn Outlook. This is the early generation of DI 3.6, and they are plagued with problems however they can be reliable in some instances. In this case, someone blew it up as hard as possible. We've never seen such a disaster with ejected parts, fire and general combustion mayhem. Follow along as I tear this boat anchor down to its smallest part.
Why am I doing this? My name is Eric, and I own and run a full service auto salvage operation located in Saint Louis. Part of our model is tearing down bad engines and selling good parts. We do not rebuild engines, merely sell parts to those that do!
As always I love all of the comments, feedback and even the criticism.
Catch you on the next one!

You should clean up the block really well and make a glass top table out of it for your reception area. That way people can stick their foot through the hole while they read a magazine. After beating the piston to a pulp, the wrist pin and connecting rod decided to elope by creating an escape hole. I’m sure the missing piece of rod is in terrible condition while as normal the wrist pin is in perfect shape.

The 3.6LLT is a really, really good engine if kept up on maintenance (like most engines). I had a 2011 CTS Coupe with 198K miles. Still had no issues whatsoever when I traded it in. People just don't take proper care of their cars and get oil changes at a regular interval. I wouldn't recommend going more than 5K miles between oil changes. These things need full synthetic oil too.

Watching you bash those heat-treated components off the engine was strangely satisfying and very funny. :) I do enjoy engines, but your sense of humor is tops. Thanks for sharing all the fun with us. Relatedly, that looks like a good engine that simply was badly mistreated. I'm guessing the oil and filter were long overdue, and when bad things started happening the filter instantly bypassed (or perhaps had been for awhile already) and the glitter got pumped through everything. There likely wasn't much oil in it, which is probably the main reason it failed. The bearings are clear evidence of oil starvation to my mind.

@DavidD-qr2vn Жыл бұрын

The bearing failure came first. What is left of the rod cap as well as the crank journal show severe heat damage. If the piston had failed first it would have been in much smaller pieces, the damage to the head would have been much greater and the rod/crank would not have gotten hot. Rod would have been bent or broken but no major heat and the cylinder wall would likely have had more damage. It is likely the heat caused failure of the rod cap or bolt, then piston hit the head, rebounded and the crank journal smacked the big end of the rod as it came back around and knocked it out of the side of the block, which broke the piston pin bosses as the piston was still up in the bore. Makes sense with where and how the piston broke.

Another commenter: Bradley Smith 6 hours ago Looking closely at the oil pump gear with the “dried bearing” material on it…that’s galled aluminum from the inside of the pump housing. The leading edge of that material is a straight line across the gear, and I can faintly make out a line down the side of it. That gear is cracked, and the edge of the crack was shaving the inside of the oil pump as it ran. The one I did a post-mortem on actually blew the bottom out of the oil pump when the gear developed a second crack. This confirms my suspicions of the oil pump lighting the fuse. If you have any other 3.6 oil pumps, inspect them specifically for cracks in the outer gear. Have you examined any oil pumps from these engines?

@fyodorberkovich8247 Жыл бұрын

Dear I Do Cars, I think you were very polite for saying that the GM 3.6 doesn't suck. Let me tell you why it does suck. In my own personal experience, I owned an early-generation GM 3.6. It basically started having the timing skip. I got rid of it before the motor blew up completely. The annoying thing was that no mechanic could diagnose it. It started as a very basic hunting idle.

I have had the luxury of working on many of these lovely failures. Synthetic oil needs to be changed more often than what is popularly prescribed because of what it does in the top end of these engines. I've seen the inboard heads in much worse condition because of lack of maintenance. Lash adjusters would collapse and kick rockers off, Cam journals badly galled and timing chains stretched and thrown off, Oh and of course! Blown head gaskets!! You would think that they would engineer a little more space into these vehicles since it's like an oven under the hood of these cars!

To GM’s credit this isn’t awful for a 200K engine that looks to have been poorly maintained and never been apart. It’s also easy to work on and looks to be fairly well designed unlike their horrible inline 5 cylinder and Ford’s horrible 24 valve 4.0 V6 with the jack shaft timing mess that requires pulling the engine to service. Had this been in an Impala I’d say, only half joking, it was probably in a high speed pursuit and blew up and caught fire.

@ads1035 Жыл бұрын

I've got an LLT in my Cadillac STS. It runs fine off of 87 octane fuel, as per both the owner's manual and 60,000 miles of personal experience. The catch is, its in your best interests to use Top Tier fuel - the octane is less important than the detergent blend in the fuel. And the detergent blend in the fuel reduces blow-by, which reduces carbon buildup in the crankcase, and by extension, on the backsides of the intake valves. It doesn't eliminate it entirely, but it does reduce it. For clarity's sake, Top Tier doesn't refer to the octane rating. It refers to a certification for the detergent blend. What's fascinating about these engines is, their ECUs actually have two spark timing tables, one for low octane and one for high octane. The ECU will try to use the high octane table at first, but the knock sensor will force it to pull timing and switch to the low octane table. This is one of those rare cases where using high-octane fuel will actually give you a tiny bit more power!

Thank You! It seems that 3.5/3.6L engines are just having a really rough go of it these days. Between the Pentastar with its... issues, the Ecoboost with its... issues... and the GM with its... issues, it might just be safer to not buy a domestic V6. I'm looking forward to see how Chrysler managed to screw up a straight 6 with the GME, but we hopefully won't see one on this channel for a couple years yet. Also, six-bolt cross-bolted mains seem to be ridiculous overkill for the High Feature family, but what do I know, I'm not an engine design engineer. ENGINE REQUESTS: Ford: 300 Inline Six, Windsor, FE, 1.0 EcoBoost, 1.4 EcoBoost, 5.2 Voodoo, 6.2 Boss, 7.3 Godzilla (probably a bit early for this one yet), 6.7 PowerStroke General Motors: 3100/3400/3800 Olds, LUW/LWE 1.8l i4, 5.7L Olds Diesel, L5P Duramax, L86 6.2 (shouldn't have too much trouble finding that one) Chrysler: Slant Six, MORE HEMIS, 1.4L FIRE, AMC 4.0/4.2, 3.3/3.8, 318/360 Honda: B Series, D Series, K Series Toyota: 1LR-GUE (lol yeah right), 1GZ-FE, 1ZZ or 2ZZ Subaru: FJ series, EZ30/36

The 6 bolt mains is specifically to increase engine rigidity, which helps make it quieter and feel more smooth. It’s not for power holding in this case. Same reason a lot of engines designed with a split crankcase (lots of people call it a bed plate). Just makes the engine more stiff and helps reduce vibration.

I committed the cardinal sin of turning the ignition key to start the Pontiac 3800 in my Grand Prix, a car with 92,000 miles on it, so I could drive it four miles home from work. The starter never engaged, as the intake manifold exploded before the Bendix had time to move, and took out all power from the battery. The engine looked exactly like that, except covered in dry chem fire extinguisher medium. It's a GM thing.

I'm a fan of the 3.6L LLT. I have one in my car, and its been consistently fun to drive with. I love the sound it makes when it revs past about 3,600 RPM, and I love the surge of power it makes as it passes that point. Its a shame, to see how poorly people maintain theirs - because they *do* need to be dutifully maintained. They're good engines, but their Achilles heel is neglect.

That is just too bad those GM 3.6s are perhaps more prone to some issues. It's a stout, nicely drivable powertrain. And can confirm, it will sit nicely at 107 at least in an Impala... It seems a little punchier/torquier than the Dodge Pentastar.

@Friend_of_the_One-Eyed_Ladies Жыл бұрын

"Perhaps more prone to some issues"? ROFL, GM 3.6L esp. from Acadia are a complete crapshow. Acadia version I believe is tuned a bit hotter, and most of the failures that we saw at the dealership i used to work at were from Acadias (one time, we had 7 of them at once waiting for parts). Yes a bit more power than a Pentastar, but the Dodge will keep going forever. Not exactly a Dodge fanboy here, but I've driven the hell out of several Pentastars, and the insides of them are still mint after 200k miles of my abuse. Cam journals and lobes looked great, head was clean inside, cylinders still had cross hatch, no trash in the pan, idle oil pressure within 1 psi of brand new. Speed-governed at 115 mph, and has the gearing (62TE) to comfortably sit there all day. That's with Rotella T6 synthetic 5W40 diesel oil, 6k mile OCI.

@@Friend_of_the_One-Eyed_Ladies The Pentastars are great engines. With good maintenance, they WILL last. There's a Pentastar that blew up at a bit over 600k miles. Why did that engine blow up? Well, it was on the original timing chain. I bet if that timing chain was replaced before it committed suicide, it would have made it to a million miles. There are a few in the 4th gen RAM Facebook groups with well over 200k miles on their Pentastar trucks and they run great. And the Pentastars in the RAMs are the most stressed engines, due to them having the highest power output in the trucks and having to carry the heaviest vehicle.

I bought a 2010 Acadia roller. Engine not running and owner said it had the cam chains changed. But he thought it was seized. No engine fire and truck is very clean. Nice SUV actually so I'm going to yank the engine and go through it. The owner was a farmer with a big operation who knows how to maintain equipment. I'm guessing this is another case of these engines not tolerating dirty oil. The GM suggestion on running the oil interval is bonkers. I would also suggest/recommend that additional ZDDP be used in these engines full time. I have a 2011 Camaro with same engine and it gets extra ZDDP at oil change way before GM interval. Good video!!
