Exactly. I'm not sure I'm buying this "no load and BANG" theory.

The BMEP of this engine at peak torque is about 188 PSI, which is very low compared to most current turbo engines, which are upwards of 432 PSI in the M-B AMG CLA45. That's 2.3 times the cylinder pressure. If the load delta was the culprit, then those engines would be throwing pistons every time they lifted from WOT.

Two engine failures in an entire career, I'm sorry but that's not even enough data to correlate anecdotal evidence. It's an interesting theory but I'd need to see some repeatable data to give it a serious look.

Wouldn't that happen at then end of every 1/4 mile run? WOT then lift at the end? I don't buy it.

I think the point is that this is when the engine is under the most stress (going from load to no load while still in gear) and if something is going to break, this is likely the time it will happen. Not that it will happen every time.

And my point is that we'd see a lot more of these failures on video as people hoon on a normal basis. The evidence isn't there that this is a normal occurrence.

Just received a call back from my service advisor.

I am a little shocked that he was upset with me for calling and then he pointed out that he got me "in a brand new camaro loaner" as if I should be grateful. He also said he "is still waiting on GM but that he has gotten them everything they have asked for in order for them to make a decision." I asked,"what did they ask for," but he would not say and he thinks it may be a few more days. I told him that I am allowed to ask questions but he did not answer any of them.

A weird world. This stuff sours me on brands forever. I loved my Chevrolet, now I may never again. It is hard to recover from this stuff for me once the relationship starts going south. I am trying to take the high road . . .

Vintage you need to relax some and take a breather. This is not an overnight process at all. Let the dealer do their job and let the process play out. I just got done emailing the Chief Engineer over the Camaro line last week and we had talks about track day events and the very open GM track day warranty. He said that as long as the vehicle was stock and the owners followed the track day setup guide the owner would be covered.

GM is one of the only manufactures out there who is offering to allow the OEM warranty to cover their vehicles on the track, no other manufactures are currently doing that from what I read.

So with that I am sure the GM Engineers are just wanting some data to see what caused the failure and see if something needs to be revised or changed so no other catastrostic failures happen to other owners.

Sometimes being the first owner to have the failure leads to some baby steps being taken along the way. Hopefully this wasn't your daily driver, at least they have you in a loaner car as of now.

The LT1 in his car is the same LT1 in every Camaro SS since late '15...and 99% the same as the C7's since late '13. It's not like the SS 1LE has a specific engine...the LT1 has been around for a few years, so there shouldn't be any "well it's a new engine" BS going on with the dealer or GM. Failures happen, GM said they would warranty these cars when tracked if stock, so give the man his new engine and be done with it.

While true, this is the 1st failure of a LT1 in a 1LE while at a track event. That is going to lead to some tear downs and diagnosis to see if it is something related to the 1LE package that could of have caused the failure, was it a LT1 issue or a Camaro issue or just a random failure.

Now the only thing I agree with was the moment it was noted the engine was done with a destroyed piston and a engine was needed then GM should ship one. But we also don't know what the inventory levels are for those engines. GM cant and wont just pull one from the assembly line in order to ship it out for the OP, it just doesn't work like that. Each engine is serial numbered and that serial number is married in the system and sequenced to the VIN it will be assembled with at some point during the assembly process.

I have seen both side of the assembly process from working in a GM automobile plant for a couple of years and also working for a supplier that sequenced parts at a location 2 miles from the plant and shipped them over.

TJay74 - you are right. It just makes me apprehensive and I need to chill. I will post again once I hear from the dealer. Thanks for your understanding. I do LOVE my SS 1LE and I want it back so I can break in a new motor and head straight back out to the track for FAST TIMES. A truly great car at any price point.

[Yendor]

I'd be upset too, especially if my calling and asking for information is questioned, and I'm a calm dude! So you have every right to be upset, but for your own health its better to stay calm.

I would bring the general manager and service manager in on any conversations you're having. Too many times the service advisor is really not on top of the situation. I would go have a straight face to face with the general manager to get a status update. A $15-22K warranty claim is certainly on your general manager's radar already.

While this process isn't overnight, the dealer should be a bit more transparent. And telling him the engine would be torn down on a Monday, but then Friday, etc doesn't help. If I was in his shoes, I certainly would be thinking I'm being given the run around and them giving me BS excuses.

Agree, and I have said this like twice already...a regular old service advisor is just a middle man. Go higher up, ESPECIALLY if you felt you weren't being spoken to in a polite manner.

[Vintage]

He was not polite and I have not even insulted anyone or cussed . . . yet. BUT, I do not want to impact anyones' job as we all have bad days from time to time. So, I will put this behind me. I have faith that this will turn out right; sometimes the process is just a little slower than I would like and I am sure Detroit would like it a little quicker too. Plus, I am so ready for my track warranty to kick in with a new engine so I can start kicking it on tracks all over the place. I really want to go to Barber and New Orleans.

I would kill for a new ZL1 1LE. $75k???
