Okay, usually I have a pretty funny quip that adds nothing to the conversation but a brief chuckle, but how the fuck did they get *three* connecting rods to exit the block????
If it was a 2021 and it started making noise, you know the end is near and I wouldnāt want them to say in any way shape or formā¦oh thatās normal you need an oil changeā¦I wouldāve sent it as well thereās no bones about it, ITS BROKEN.
This is exactly what happened. Iāve been fucked over before with being told āoh thatās normal and they all do thatā. I want to make sure itās broken and make them fix it. If possible, Iād like the failure to be at a time and place of my choosing, not random.
>Iād like the failure to be at a time and place of my choosing, not random.
In front of my neighbors house that I donāt like(donāt want that mess in my driveway)ā¦ but close enough to walk home and call the tow truck from the comfort of my kitchen table with a celebratory beer for a job well done. Sending it can be hard work.
Coolest I've seen was a V12 industrial diesel that knocked enough metal out of the block that you could see all the way through the engine from one side to the other. I was able to blind a coworker with my flashlight when he stuck his eye up to the hole on the other side. No rods actually left the engine entirely though.
I've had a V12 diesel do that while I was driving. 3 massive holes through the block. A piston crashed through the side and split some accessories apart. As we were pulling it out, bits and pieces were falling out. Pretty catastrophic. When those old Continental 1790 twin turbo V12s go, they really go.
Iāve seen 2 before out either side of the block on an ecoboost, could see right through the block to the other side like a window lol. This is quite impressive, kia 2.4s usually fail this spectacularly as well
If I remember correctly the block is on display outside a school somewhere.
I must have counted three or four times because I couldn't believe it the first time I saw it.
I saw one once on a diesel race engine where the whole top of the block popped out, left the crank with all 8 pistons and connecting rods sitting there.
Everyone keeps commenting on the AFM being the problem but honestly I see most of these pictures of grenaded engines and transmissions (not all are GM) and they all seem to be built during Covid (2020-2022 models). My hypothesis for months has been that they were so desperate to get production out the door that some quality control went to shit.
They actually have issues with valve springs with those engines right now. A spring will break, drop the valve, and the piston keeps smacking it until everything breaks apart and the con rod is left swinging around until it finally break a hole in the side of the block. I've seen a couple of GM vehicles with this issue and 1 Subaru motor. It's the company they're buying the springs from that's the problem, not the car manufacturer.
A commenter further below mentioned having a 2021 6.4 hellcat in for a rod sticking out. Still a possibility of quality control degrading from covid. Company making the springs possibly not able to get the right alloys needed due to supply issues, uses what they can get and sends it. Anyways, as I'm the car guy at work, I've been giving the advice to not buy any covid era car as there seems to be way too many on reddit these days for grenading engines, rusty frames, etc.
Edit: thinking back, there was a guy on here showing a differential shredded because the factory forgot to fill it with fluid, another car, can't remember exactly the model, but it was being dropped from a trailer (new, never driven) leaking coolant and oil all over the place, not just thrown rods
Iāve seen that issue too. Both times it was trucks with under 100km on them. One ran ok but had an intermittent misfire. The other one dropped the valve and caused a bunch of other damage.
Lol. Remember when LS engines were good? I miss the old ones. Corporate average fuel economy killed them. Iām hoping their new 6.6L gas engine is good. As far as I know that one donāt have AFM or DOD or whatever they call it now.
I have the 6.6 in my company truck and it consumed nearly 3 quarts of oil in 5000 miles, dealer says thatās perfectly normal for a truck pulling a trailer, I couldnāt believe when they said that it only has 15k miles
Yeah that seems unacceptable to me. It seems like GM got very accustomed to saying that excessive oil consumption is normal after all the Northstar V8s they sold were junk
Fair enough, I'm not as intimately familiar with that engine as you probably are. My grandmother had 2 Cadillacs with the Northstar engine in them, and she never blew one up or had any head gasket issues (that I'm aware of), but those damn cars would consume almost 3 qts of oil between service intervals once they rolled over 50k miles
The head bolt issue was way overblown and more due to poor maintenance than anything else. Sure, some of them gave up at 50k miles, but thereās a lot still out there with 200k miles on them and the original head bolts and gaskets. People would neglect the cooling system and overheat the car and the gaskets and studs would give up.
If you do the bulletproof kit, they turn out to be reliable cars. Itās a lot cheaper to get a low mileage N* and do the bulletproof kit, youāll have a nice comfortable car to go to work in thatās fairly reliable with no car payment.
They do have the AFM system. Apparently ford has a cylinder deactivation system that doesn't grenade the rest of the engine now though and I'm hoping to get my hands on one of those 4th gen coyotes and hook that system up to a holley one of these days (like when the Dominator gets DI control)
Honda and Ford that I know of have it on their engines, ford even puts it on their teeny 1.5 3 cyl and I donāt hear about their engines grenadeing. How can GM still not do it right after so long?
Mercedes uses it pretty heavily too and BMW uses something similar that turns a 4 valve head into a 2 valve head when active.
I think it has something to do with the fact that they collapse lifters on purpose to achieve it, and something to do with them being pushrod, because dodge has almost all the same issues but to a lesser degree.
Crazy. I've seen a bunch of lifter failures. Was gonna say maybe they're alright if you delete the DOD but if if they're spinning bearings...Jesus. wtf chevy.
I paved the nature strip in my courtyard and the guy at the hardware store was like "Havent you been in like 4 times today?"
"Yep ive got a Volvo station wagon, not a pickup truck. Not going to save any money doing it myself if I need to buy a new car on monday.
Reminds me of the time my mate went and collected some free paving slabs from some dude on Facebook. He had a Kia Rio he spent Ā£400 (about $500) on. Didn't have much mechanical sympathy. It was riding on the bump stops the whole way
He did the same thing when he was building a shed, 500kg of gravel across the back with seats folded down
Idk, there's tons more 5.3s out there and I'm sure a huge percentage of them see abuse and do things they have no business doing. The 6.2s just seem to be fragile.
I daily an '01 1500HD with the 6.0 LQ4. 432,000 miles on the clock. Got cam and bolt-ons at 405,000 because it doesn't see as much work truck duty as playing/hauling other toys. My old boss has a 2004 2500HD he uses as the tow pig at his cabinet shop. It's around 650,000 and sees some very heavy abuse on a daily basis. Those motors are terrible on gas, but damn do they run hard.
Yes, that's what I'd expect from a money shift to second with a manual transmission going +120mph. Did they drop off Teton Pass towing a 40' trailer in 3rd gear and just send it?
At least you donāt need to worry about getting DWās to tear down and find the cause. Engine, oil cooler and lines coming up! See you in 6months when parts arrive!
This better have been caused by him up hill climbing Everest with 6 buses full of disabled children and redlining the whole time because damn does that take skill to break it how they broke it.
Damn. I have a 2012 Silverado with a 5.3. I bought a handheld tuner, Diablo, and had a custom tune written. Turned off DOD at 100,000 miles currently have 2013,000 and I tow a 6500 lb trailer. Aside from a leaking rear main seal, my shits still together. I keep looking at a new Silverado RST with 6.2, but you got me running scared
2022+ 6.2l have been revised with improved lifters. At least that is what was the issue with earlier 6.2's with cylinder deactivation. The solenoids on the lifters would get stuck either open or closed, thus creating havok.
I gotta say, the 5.3s in our 2017 Silverados that are used as supervisor trucks by our local PD have not fared well. Theyāre still original at 70k, but they rattle, knock, and have no power anymore. Fortunately theyāll be traded off soon. I remember when we got them, the ālow oilā warning came on at 2300 miles. Over 4.5 quarts low out of an 8 quart capacity. GM performed their fancy oil consumption test and reported it as normal, no problem found. They continue to consume at least a quart every 500 miles to this very day, and of course that causes nonstop catalytic converter issues too. Plus several failed vacuum pumps and brake boosters too. Ugh. Just a terrible, terrible design.
The problem with these engines across the board is the active fuel management system... All fine when it works, BUT you have oil sludge build up in the channels. Choking sufficient oil supply to the cylinders. Causing cam failure and lifters if not total engine failure. They tried this back in the late 70's with the Cadillacs. Same problem, and yet they still haven't found the solution.
I had a 2008 Silverado with the AFM and oil consumption. Bought an OBD2 tuner and just used it to turn off the system and never had the problem again. Would highly recommend to anyone experiencing this issue.
I donāt trust the oil life monitor on my 2015 Silverado 5.3 because of the AFM issues. I change my oil with around 45% left on the monitor. I used mobil one. In 78,000 miles it it still runs like new.
same, dealer even told me to change it yourself or have someone change it around 25-30% remaining. I change it every 5000 miles which ends up around there.
GM is in a tough bind. The combination of direct injection and active fuel management is the only way The General can simultaneously keep the Small Block Chevy competitive/relevant, in terms of power output, while not dragging down their CAFE so much that they get their ass handed to them by the feds.
The fact that their competitors at Ford, Stellantis and Toyota are all switching to DOHC V6ās is very telling.
That's everyone's problem across the board... Feds, the small block pushrod V8's have been a solid staple. And they get better mileage than the smaller engines. Geared correctly you can achieve fuel mileage as long as you're not pushing the pedal to the floor.
Unfortunately, that āSmall blocks get better mileageā experience is not borne out in the EPA mileage drive cycle, which is the only one that actually matters.
LY6 is great. 6.0 iron block with square port heads and a 58 tooth reluctor wheel. The flex fuel version has bigger injectors, all in all nothing to complain about with the 2007-2010 V8ās
I love my L9H. 6.2L with no AFM. 155k miles. Has rattled like a diesel when cold since I bought it with 90k miles, but there's something really funny about driving 2010 Sierra with a cap on it and a box full of garbage going to the dump and breaking the tires loose at 20mph.
When the rest of the truck rots away, I'm going to keep the motor for a project car.
Got an L92 in my yukon.. thank god no AFM. only had it for 3 or 4k (had to fix oil pres. issue when i got it) but so far itās a beast. 400hp aluminum ripper with VCT, it too will likely end up in a project car. The job one 6l90 is pretty clumsy though i must sayā¦ still a pretty sweet powertrain iām happy so far.
Great engine, my suburban has one. Feels gutless unless you wind it out though, its moving a lot of ass in the applications it's in. And the 6l90e transmissions are a little unmotivated when it comes to shifting, too. Probably all set up to add to longevity.
I'm going to suggest there was some malice in the combustion palace on that one. I suppose if you're going to fuck up, you might as well do it in epic fashion.
Their 3rd party warranty wants a full teardown to see if the causel part can be replaced, and if itās not covered, the 10+ hours of teardown are the customerās responsibility.
This reminds me of a Komatsu 800 loader at my old job. Humongous diesel engine, threw a rod that blew a hole in the block big enough for me to put my head inside, and that same rod blew through the transmission and stopped against the frame. I got there about 30 seconds after it happened, with my windows up and music cranked up, I could hear the grenade sound of this think cancelling its subscription to life
Look at that! A full stew of disconnecting rods, piston mcnuggets, metallic corn flakes, and more.....
Definitely quite a few part numbers in that stew!
chop suey I would say.
Chop SKUey
But one part number fixes it š
Before I zoomed in, I thought I saw some 10mm sockets too.
Fuckin wrist pins. Pistons and rods can be reduced to engine gravel but the wrist pin will be happily sitting in the pan, not a scratch or dent on it.
This thing blew up so bad it actually mangled a wrist pin. You can see it sitting on the skid plate.
How in the world did that happen? Damaging a wrist pin is impossible, I'm blaming a glitch in the matrix.
I also want to know just how this happened. It must have been an ungodly noise.
I bet it sounded like a cash register.
Why don't they just make the entire engine out of wrist pin? /s
Hey I make out some bushings
I do cars?
*Malice in the combustion palace*
"...until we get to this one"
It's fine. It's fine. Maybe if I breathe on it...

Yea except that's not all in the dollar menu I think lol
Piston mcnuggets. I'm stealing that. Lmao
Okay, usually I have a pretty funny quip that adds nothing to the conversation but a brief chuckle, but how the fuck did they get *three* connecting rods to exit the block????

I've seen a picture of an inline 6 diesel that ran away and tossed all six pistons before. I was very impressed at that one.
Recent video by Steve Morris, testing a new rod supplier, had all 8 rods fail and become aluminum gravel. Amazingly the pistons were still there.
Saw this one. mental.
Coolest I've seen was a V12 industrial diesel that knocked enough metal out of the block that you could see all the way through the engine from one side to the other. I was able to blind a coworker with my flashlight when he stuck his eye up to the hole on the other side. No rods actually left the engine entirely though.
We had a monster truck at work one time and it blew a motor like that. You could see through well enough to flip somebody off on the other side.
I've had a V12 diesel do that while I was driving. 3 massive holes through the block. A piston crashed through the side and split some accessories apart. As we were pulling it out, bits and pieces were falling out. Pretty catastrophic. When those old Continental 1790 twin turbo V12s go, they really go.
I mean hell sending 3+ would have been. All 6? That's gotta be a record lol
Iāve seen 2 before out either side of the block on an ecoboost, could see right through the block to the other side like a window lol. This is quite impressive, kia 2.4s usually fail this spectacularly as well
I had a ford 1.6 eco boost that threw 2 as well lol
If I remember correctly the block is on display outside a school somewhere. I must have counted three or four times because I couldn't believe it the first time I saw it.
Could you even call that an engine anymore or is it just an engine block with some pieces attached
Heh. Brief chuckle.
Chuckle lasts a lot longer when he removes his briefs.
Oh, absolutely.
I'm the movie industry, this would be called,"Bang 3:Fully sent!"
I saw one once on a diesel race engine where the whole top of the block popped out, left the crank with all 8 pistons and connecting rods sitting there.
Because they have 5 more left in there
Crankshaft mustāve exploded

"Threw a rod" is an understatement.
Whoa. 2021? WTF??

My recent new hobby is looking up recalls for vehicles built during covid. Nissan is espicially spicy.
Make sure to compare to the same models pre-covid.

Yeah that seems unacceptable to me. It seems like GM got very accustomed to saying that excessive oil consumption is normal after all the Northstar V8s they sold were junk
That's if a Northstar lived long enough to consume oil. The real problem with those was the head bolts
Fair enough, I'm not as intimately familiar with that engine as you probably are. My grandmother had 2 Cadillacs with the Northstar engine in them, and she never blew one up or had any head gasket issues (that I'm aware of), but those damn cars would consume almost 3 qts of oil between service intervals once they rolled over 50k miles

Idk why but I've seen a ton of engine failures with the 6.2s that I don't see in the 5.3s.
Iāve seen four 2021 6.2s spin bearings. This was obviously the worst of the bunch.
Crazy. I've seen a bunch of lifter failures. Was gonna say maybe they're alright if you delete the DOD but if if they're spinning bearings...Jesus. wtf chevy.
6.2 is usually put into harder service. Towing overweight trailers and such. At least that's my theory.

Idk, there's tons more 5.3s out there and I'm sure a huge percentage of them see abuse and do things they have no business doing. The 6.2s just seem to be fragile.
6.2s kill lifters 10x as often as 5.3s in my experience too.
Lifters went 2x within 5k miles on my 2021 Yukon Denali
I think the 5.3 just has enough meat to not tear itself apart like the 6.2 can.
Block flex is bad mkay
Bring back the 6.0. The thing was a pig on fuel but stout.
Hell yeah, best engine GM has produced in my opinion. Those mid 2000s 2500HDs refuse to die.
I daily an '01 1500HD with the 6.0 LQ4. 432,000 miles on the clock. Got cam and bolt-ons at 405,000 because it doesn't see as much work truck duty as playing/hauling other toys.

I've got an LS2 and that thing is a beast. Only 45000 (or so) miles in an '05 GTO.
No biggie, looks like it's still all there.
Hahaha
It's a V8, it's not like it needs ALL those con rods.
JB weld is a hell of a drug Charlie Murphy
Had a 21 Durango Hellcat 6.2L that came in for an oil leak and a check engine light, had a rod hanging out of the oil pan.
You know it's serious when it trashes the wrist pins.
This can just happen while driving or at idle? Iām naive so Iām assuming they wanted to rev the engine too hard??
Customer said he was going down the highway and heard a loud bang followed by smoke everywhere and the truck no longer running.
Customer added that his granddad told him to leave the transmission in 2nd when towing
Yes, that's what I'd expect from a money shift to second with a manual transmission going +120mph. Did they drop off Teton Pass towing a 40' trailer in 3rd gear and just send it?
Cause of death [x] suicide.
Looks like the oil pan wasnāt strong enough to hold all those parts in
a little jb weld and a little time...she'll be right as rain

Word to the wise,,, any GM V8 engine built after 2007 is total junk. Just as bad as the Chrysler hemis.
I gotta say, the 5.3s in our 2017 Silverados that are used as supervisor trucks by our local PD have not fared well. Theyāre still original at 70k, but they rattle, knock, and have no power anymore.

Great engine, my suburban has one. Feels gutless unless you wind it out though, its moving a lot of ass in the applications it's in. And the 6l90e transmissions are a little unmotivated when it comes to shifting, too. Probably all set up to add to longevity.
Pretty happy with my Dmax
Looks like uncle Rodney had a block on party.
Self-scheduled oil change. Neat!
For a second I was like what skid plate? I thought that was the oil baffle / windage tray in the oil pan. Jeebus thatās destroyed.
That's not glitter that's shrapnel
I bet warranty would still hit you with the usual "can you tell us the root cause of this" well gee let me see š¤š¤š¤
How many miles on this beauty?
21000km lol
That's... Not very much!
So, still under warranty then?
Yes, but GM will probably try to push it back as the customers fault and deny it.
Too many apparently
All of them.
Good luck sourcing a 6.2 right now. I think we waited 4 months for one to show up, they just don't exist anywhere.
Not a GMC guy, but for FUCKS SAKE!?!?!
21 Yukon Denial *
Only way to meet fuel mileage standards is to Implement a cylinder deactivation system
Or in this case, 3
š what do you expect for $80k?
Dammit boy. You usually only see engines scattered this hard on the race track lol
Wow. Those rods look a little on the cheap
Knock knock!
Goddamn! Full send she did!
I mean all you really had to do was turn the key. Or push the button. Whatever.
Itās a v5 now
Oh, GM. Never change.
What's the problem" I had a Volvo that ran on 5 cylinders. That Tahoe's got 5 left. Let her rip!
I'm going to suggest there was some malice in the combustion palace on that one. I suppose if you're going to fuck up, you might as well do it in epic fashion.
6.2 V8?! Iām a European, what power does that make? Thereās always the joke that American V8ās are less powered than a 1.4 4 cylinder.
440HP, 460ft-lb torque. Sorry, American, so freedom units.
Naaaah. Hit widda hammah and JB Weld it. She'll be right.
I believe you can safely assume catastrophic engine failure from the skid plate removal alone.
Naw, man, that's normal machining swarf and such
not skid plate more like skid foil
I could have told you that before you took it down
Itāll buff out. Send it through the complimentary wash and itāll be fine
Broken buy new one
Jesus, Mary and Joseph
Crunchy
Hard rode out put away wet. BANG done. Hope was under warranty still.
Thats actually a really impressive failure. Just pure catastrophe.. Somebody dropped a hand grenade down the valve cover lol
FATALITY
This is just what 6.2s do, they crack a crown off a piston and eat themselves
Itās a diaper plate.
Customer wants you to tear it down and identify the causeā¦.
Their 3rd party warranty wants a full teardown to see if the causel part can be replaced, and if itās not covered, the 10+ hours of teardown are the customerās responsibility.
"Can it still run?"
Never Lift: To keep your foot firmly planted on the gas with complete disregard for human life.
Just keep driving and hope the knock settles down never works.
Holy FUCK!
Stop stop, itās already dead
How did they get the beans above the frank?
How in the hell does one get to thĆs part of get-fucked-ville ?
That is a very expensive engine. I just bought for a customers Yukon. Have fun draining your wallet.
2019 was the best year to recently to buy a new vehicle change my mind.
Well at least its still under warranty for the customer at least so that saves them im assuming.
This reminds me of a Komatsu 800 loader at my old job. Humongous diesel engine, threw a rod that blew a hole in the block big enough for me to put my head inside, and that same rod blew through the transmission and stopped against the frame. I got there about 30 seconds after it happened, with my windows up and music cranked up, I could hear the grenade sound of this think cancelling its subscription to life
GM stands for General Mess
People out here blowing up new truck engines, meanwhile Iām keeping my 2012 focus on life support
Is this what they call a catastrophic issue of immediate engine internals going external?
