The only problem I ever heard with them in the arcadias/tranverses was that they had a tendecy to stretch the timing chains. But I had heard that problem was fixed by now.

The timing chain issue is old and should have been fixed well before the camaro went into production.

If this is becoming more widespread then it seems like GM didn't do a good enough job of making sure the engine parts are durable enough to handle direct injection.

My engine does not have DI, and I guess after hearing about this I'm glad I don't, I'm happy to have 45 less HP if it means my engine won't blow up.

Yeah it seems that part of the issue is that they squeezed as much power as they could out of this motor.

Honestly, that kind of attitude is partially what got GM into bankruptcy.

There is no excuse for a single engine to have catastrophic failure like this within 9,000 miles and proper oil changes, no abuse, and no modifications. To even excuse one out of a million is not acceptable.

yea its sad, i'm seeing "LLT IS BLOWN" threads like once a week now =(

Wife's 2009 Acadia that we bought in February 2009 had to have it's stretched timing chains replaced at 32,000 miles... that is not a well before the Camaro went into production...

You are being sarcastic I hope - no company can be perfect and it is not always the product they produce but the support they offer after the sale that counts as much as the original quality.

GM is doing a great job all around - Buick was rated with the highest customer satisfaction bypassing even Mercedes and Lexus.

These are mechanical parts - obviously things can and will go wrong.

Actually there is a really good excuse. It's called shit happens. Anytime you have something mass produced you're bound to have a few failures.

Ever buy a bag of potato chips and get that one burnt chip in the bag?
164,000+ Camaros and 2 chips with blown engines... Such is life.

There are a lot of moving parts in an engine, they're not always going to work flawlessly.

I feel bad for the OP, I'd hate to be in his shoes.

Dude... love the wheels, dunno how I feel about the back window - I'd want to see it from more angles before I make up my mind.

Also, I suppose GM may not have been on the ball with the timing chain issue. I hope my LY7 doesn't have an old one.

DarkneSS, no problem, life does get busy for us all! Call me when you want if you need.

I have also heard about the timing chain stretchin issue and it should have been addressed before the first LLT was dropped into a 2010 Camaro. The mechanic I spoke to that was working on my LLT told me about this when I saw him pulling out my LLT from my previous Camaro. He had not yet seen a single LLT with a bad bearing, nor had he rebuilt one from the shortblock. Pulling the front off an engine and flipping the timing chain is far less invasive than a block tear down with head, cams etc.

I agree that 1 or 2 bad engines can be acceptible in a production run in the hundreds of thousands, so it kinda sucks to be me or DarkneSS right now in the draw for a new car... I am thinking that perhaps more LLT issues will popup, however, as history repeats itself. My friend is an automotive tech that works the software that runs the robotics that build engines. He told me that when an issue exists in the software or procedure that runs the robots, problems in the code or process may make issues repeat themselves. SO if there is an issue it will be reproduced again and again until the next re-assesment of the procedure. This means that the very aluminium filing/burr that was not flushed out in the oil cutting stage re-occurred until it was discovered and corrected. Then said metal ended up in the bearing material, corrupting it and dooming it for rapid failure. Did your metal bitty end up doing the same thing or di it end up in your first oil filter? The winning question is then, who has a problem in waiting and which engine got that aluminium shaving caught up in the oil filter?

If I were a current LLT owner, I would be changing my oil and filter more often for awhile! My 2SS/RS is now on order! ;')

Here is the situation and I'd like some feedback from you guys:

Blown/Broken bearing on cylinder #4, the entire bottom end basically needs to be replaced. Today was day 23 and the tech and service manager themselves told me the parts are on back order and I probably won't get the car back until two weeks from today. If that is true that puts my car in the shop well over 30 days, about 36 to be more exact.
They didn't outright say it but they definitely implied that this is becoming a more widespread problem as the parts they need shouldn't be on back order.

Unacceptable, and no, talwell, I was not being sarcastic.

Proper R&D and testing of an engine design, and then proper assembly by the people who assemble them ensures such problems do not happen in such a short period of time.

150,000 miles and lot of racing, hard driving, modifications, etc? Sure, I'd wager it would happen more often than not.

9,000 miles, no abuse, no modifications, and proper oil changes? That is inexcusable, poor quality control by GM.

Even ONE is a problem and should be taken extremely seriously by GM - every person involved in that particular engine (and they can trace back to every hand that has touched it from start to finish) should be put on 3 weeks unpaid leave until engineers have torn it down to the last bearing, ring, and seal to determine exactly what and how it happened.

In the mean time the OP should have a BRAND NEW engine installed, no questions asked by GM or the dealer. Given a full 5 year, 100,000 mile warranty on the engine from date of installation, and GM should even go as far as have the OP report back to them on how well his new engine is performing, his fuel economy numbers, and answer any other questions he may have. It's called customer service, and GM is dropping the ball on it here as well.

To make excuses for GM as though "it's only one" sets the example that quality really isn't a high priority.

There are many people who still remember the 1979-87 HT4100 and V8-6-4 368 Cadillac engines - the service GM is providing the OP on his 2010 Camaro is exactly what they were providing those poor saps who spent big bucks on Caddys only to have them break down in 30,000 miles or less. GM would only help get the engines replaced after months of going back and forth with owners.

I challenge anyone here to prove me otherwise.

T_T i have LS, I hope any of these would happen to me. Rebuilt engine would drop the resale price down like there's no tomorrow

I have an LLT that they "fixed" and the rebuild had my parts spread all over a mechanics' bench down to the shortblock. They gave it back to me "rebuilt" and the check engine light lit up BEFORE I even left the dealership... It wouldn't start, misfiring so intensely that the hood shook violently before sputtering to a stop. The car died on me while I was driving along with my whole family in the car (good thing I was not on the highway at speed...)

When I brought it back to the dealer, they cleared the computer and told me to come on down to pickup my car, all was great! They did NOTHING other than clear the CEL's. I told them clearing a computer AIN'T fixing it as the source of the engine code is not dealt with... when I was going to bring back the loaner the next day, they couldn't even get it out of the garage! It's been two weeks since then.

Even if they did fix it "well enough" for now, it's the long term damage that cannot be seen "today" but will certainly impact the long term viability of the engine once out of warrantee. It's a very complex engine, much more so than the LS3/L99 series that are based on a single camshaft with pushrods. Most GM mechanics just don't know how to put one back together as it was by robots at the factory. THIS is the reason that I have opted to buy an SS as I should have in the first place! I cannot talk about how GM has started to work with me on this deal yet, but my current V6LLT car is leaving my stable for sure. There is NO WAY that I would keep a car that had an engine rebuild with so little mileage. Mine blew up at 6400 Miles.

How would you feel, Mr. Sonoma, if your engine was rebuilt with that type of mileage....would you feel good about it? What would YOU do?

eBH

As I said in my post of course I would prefer a new engine but a rebuild DONE CORRECTLY wouldn't be an issue for me. Now after leaving and having the rebuild crap out I would be pissed! I don't blame you for wanting out of your car. The main purpose of my post was not so much to debate which is the better option but to say that although some people have had unfortunate engine issues it doesn't mean the LLT is a bad engine. Some people are grabbing their pitchforks and troches and I just wanted to calm them down. I hope everything goes well for you in the future either with your current car or a new one.

Sticking accelerator pedals are cause for mass hysteria. An engine failing here or there out of THOUSANDS installed on multiple models is not a huge problem to a company the size of GM. (not saying it's not a problem at all) But they've got bigger fish to fry.

3 weeks unpaid leave?!? Are you f'n serious? What if that person was you? Would you still feel this way if you were sent home from work without pay for 3 weeks? Give me a break.
