Contact local GM rep first and see what they say then go up the food chain. They know this is happening all over so maybe they will. Let me know in private message if they won't and I'll give you a contact # that might help. Oh and be polite you catch more flies with honey than vinegar.

Thanx Doug. They have called me and confirmed that i need a new motor. 15k$ is what they quoted me.
I explained myself and asked if they can "help me out". I am going to send them my service records.
All i know is that i cant afford a new motor from them. Thats almost half the price of what the car is worth, today.
Ill let you know Doug. Thank you

Man...I sorry to hear about that. I hope things work out for you.
I plan on doing something to mine in the Fall. I hope it lasts that long. Russian Roulette

No. The rep said that they dont know what happened to it. They also said that they might not be able to determine the cause of the engine failure, even if they do open it up.
However, they are entertaining my goodwill requests. I just got of the phone with them and they are going to check the ECU for any re-mapping
; my car is stock.

GM - please step up and take care of this customer (OP).
Do the right thing, GM.

Food for thought: Supposing that GM does step up and make a goodwill warranty repair, paying for 50% of the cost. that's still $7,500 out of the OP's pocket for another factory stock LS7 with the very same QC problems that all the rest of the LS7s have.
I respect whatever OP decides, but as for me, THERE IS NO WAY IN HE11 I would pay my hard-earned money to buy another crap engine just exactly like the original crap engine that GM put in the car the first time. No Way!!!

please. tell me more. I have been looking online. I have found replacement motors, but not at half the price!! they r all a bit more expensive. And i dont trust the stock ls7 motor any more. I would rather have something else in it now. Something with more power but without a crazy cam loop. Any suggestions? thanx
- $2800 - Brand new bare LS7 block from GM
- $300 - used LS7 crank
- $350 - complete set of used rods and stock pistons
- $250 - new stock LS7 piston rings
- $100 - coated rod bearings
- $250 - balance rotating assembly
- $150 - main bearings
- $500 - engine assembly
$4700 total and I'm out running low 10's with the car again.

You'd be surprised at how inexpensively you can build one pretty much completely from scratch as I just finished going through this myself:

OP, sorry to hear about your engine, this problem is not going anywhere no matter how many "How many people with no problems?" threads are made to gloss over it. Glad we don't have to listen to the prosecution's abuse claims now against OP.

How was your balance job so cheap? Non LS7 rotating assembly but a steel crank, crower rods, forged pistons, etc; set me back $1300 for balance job. I had some block prep and clearancing done as well but I guess it's who you know....

$4200 for a beefed up LS7 as opposed to ~$15K for a stock LS7 is, to me, cheap insurance.
Side note, Sorry, OP, for your troubles. I keep dumping money into mine in the hopes of avoiding this exact catastrophe. At the rate of failure lately, mine will be among the few modded cars with an engine that's original to the car.

To the OP - sorry for your troubles. I too hope GM repairs this on their dime as the motor is still very low miles for one to consider this to be normal failure... I'm not one who normally bangs the drum, but maybe it is time as a group of owners for us to think about filing a class action lawsuit... There has got to be a few attorneys on this site. GM's response to this mess has been unimpressive to say the least. They have now sheepishly, sort-of, admitted some motors may have a design flaw. We owners are now faced with the burden of having to invest our own money to fix the flaw (to which we are still somewhat guessing what the exact flaw is except that it may be valvetrain dynamics, geometry, QC, or a combination thereof) while simultaneously surrendering our factory warranty. My 2008 has less miles than yours and the warranty has expired, but for those with 2009-2013s - GM has left them in a predicament. I think they are just going to wait this one out as there were, after 2008, very few LS7's built - so the number of warranted LS7's are ~5000 now? It's a lot cheaper for GM to deal with each case than admit to the flaw and fix all of our vehicles. Disappointing, but this seems to be their tactic.
I agree with subfloor - the only reason the LS7 is so expensive is that it was built by hand. It would be 50% less if it were built like the LS2/3. Perhaps the tolerances would be better but considering the problems with the valvetrain, tolerances seem to be the least of GM's problems with that design.

Well...i guess its my turn now. I put a hole in my ls7 motor yesterday. From what i can see, there is a hole in my block. Ill hear from the dealership today. Thanx chevy!!!! I figure ill just cough up 15k+ to get my car running again. And i told myself that i was not going to rob any banks this year. Very disappointing.
Stock 2008 Z06. B&B fusion cat back (stock). Someone sell me a replacement motor.

probably a bad downshift..... 
Sorry for your loss OP.
Side note:
I was on the highway yesterday and a guy with an E92 4 door M3 pulled up along side of me, so i did a nice 3rd gear pull to let him hear it (obviously didnt go past the speed limit). We exchange thumbs ups, and he proceeds to tell me he has a Z06 that just dropped a valve and is now in a local shop getting rebuilt. Not sure if he posts here or not, but just seems to be staggering the amount of occurrences. That makes 75% of the people i personally have met with a Z06 face to face that have blown the motor...mine being in the "post headwork still safe for now" category.
