My Viper was solid, and an oven to ride in.
But, there was a round where Vipers had oil starvation issues, that's why they developed the oil pan with a swing arm in it.
Z06 why easier to track and live with. And, no I haven't track it nor will track my '09 Z.

Could be a cumulative affect from a sh1tty tune. These things can take time to surface just like the oiling issue, which more than likely is also cumulative. Otherwise every Z would pop on the very first hard driven track day, but they don't...

I guess no way to tell for sure without digging in to it much more but if I had to put any money on this I would say the spring just failed and dropped the valve....

I think you need to go to the dealership that tore down your engine. Ask to see the engine, all parts removed, and what failed. It would help if you had a digital camera & someone that has a clue about engines. If the tune was bad & overheated the valve, it's possible there will be some telltale signs still visible. However if you see a broken spring or retainer, its very unlikely the tune caused that, unless the rev limit was raised or a downshift was missed.

You seem to be adamant about GM being able not to detect a previous tune that has been flashed back to stock, but offer nothing to back up your assertion. How about you having a tune put on YOUR car, then have it flashed back to stock, then take YOUR car to a dealer and have them run a scan and have them send it off to GM. Are you willing to chance GM blocking your warranty, if they detect the previous tune?
I'm sure others would also be curious about the outcome.

This just highlight the huge lack of due process, and further illustrate that there's no customer protection. The guy bought a used car, was told it was stock and under warranty. The engine blows, now GM says it isn't under warranty because it was re-programmed, and the op said he never did it...I'd be sueing until I have a new ZR1 paid for in my garage...but that's just me! the GM BS has to stop somewhere, and this is a good example...and there must be some customer protection for the person that buy a used car from a dealer.

I agree. There are just two real possibilities here:
1. The dealer sold you the car as a warranteed car.
2. You bought the car "as is"
If it's #1 then the dealer MUST stand behind the car or take it back. If it's #2 (and they would have had to make that very clear to you and you would have had to sign a thing that said so) then it's your problem.
All the rest of this is a side show.

I am not sure of it because I have other sources than this forum that have stated there is no counter. Now I have also seen other sources stating that Duramax trucks ECM have alot more anti-tune device counters momojumba than the C6.

Sorry but I don't agree.
The fellow bought a used car. Who knows what the car has been through that might have precipitated the problem. His issue has to be with the selling dealer that either didnt do enough homework or misled him. If sending an ECU scan to GM for verification is what has to be done to verify no computer mods then dealers should do it. What if it was a cam that was in the car? or aftermarket pistons say. Should GM provide warranty? No. Is it reasonable that the selling dealer tear the motor down to verify it is stock? No. But once they say GM warranty it is the dealer that has to come good. Will they? Not likely.
This is no different than buying an old muscle car back in the day.......
Caveat Emptor!

^ well we agree on one tid bit that the dealer should do more homework hence be more "responsible". Still not the newer owner's responsability though, and if GM doesn't have the ecm reccording the date, this could be interesting in court...but I guess it would take alot of money for that too...

I fully agree...VERY, very seldom you will see something like this happen right away...it usually takes time for these things to display into symptoms or finally give in.

good point. Wow, I can't believe these stories...amazing. Sorry to hear about your troubles. I still can't believe these motors aren't holding up, even with a tune....did GM make these engines to be built to the very limit from the factory and any power adders after that are set up for catastrophic failure?
Unsure what I'm going to do......crazy wife suddenly wants a career change and says "I want to go to med school now?

The fact these things are blowing stock with no modifications (at least 2-3 this week?) really makes me wonder the quality of the motors or if there is a design flaw.
I am surprised nobody has looked into a class action lawsuit.

There was a thread from 2 weeks ago about a customer of mine that blew. His car is being repaired under warranty and it is bone stock. I think there has been closer to 1 a week and of those, less then half are bone stock.

This is an example of it.
jmalto, what 2-3 stock with no modifications LS7s have blown in here this week?
Point them out.

That's the issue!! The diehards will have their defense???, but I've modded way too many cars and usually there is 1 critical point you don't cross. As long as you stay under that your golden these LS7's seem to have numerous problems and fail for a number of reasons.

"Where does it end is the question?... For many, it never ends. and shame on them for bitchin' when it blows! Track tires, suspension, and a tune is pretty substantial for a car that's already pretty ballsy. It comes out of the box with over 450 RWHP
...WTF man???Next question is, who can really use all this power from the factory efficienty??? Answer: "Not many of us...period" So this fruitless search for power is in vain and is detrimental to our warranties.
There's are some that "can" use this stock power and two or three come to mind...Ranger, Jamie Furman, Frank Gonzalez...these guy run the shiz out of their stock cars on the track and strip with AWESOME results!!!
Now I would wager that "very few" on this forum with 100 more horses could touch these guys...now tell me... "What's the point of modding a car with this kind of power, and comes with a 5/100,000 drivetrain warranty when you could be throwing the warranty out the window and probably haven't gotten the most out of the 505HP it came with???"

I purchased the car with 1500 miles on it and it was completely stock, or so I thought. I heard stories about GM denying warranties so I never touched the motor, only changed suspension and wheels. Now GM says that someone did a tune on it before I bought it and my warranty is void.
First off I don't understand why someone do a tune but keep the stock headers, exhaust, intake, etc. then flash it back just to trade it in with 1500 miles... Doesn't make sense to me. Apparently one of the 15 or 20 numbers in the CPU printout didn't match something it was supposed to. I even had the car in for a check engine light back in December and was told that the car needed a software update (something about the cats) and they didn't say anything about the cpu not being stock - sure wish I knew then and I could have bought an aftermarket warranty or something.
I went all of the way through the district rep and was told there is nothing they can do because its not GM's fault. She actually said I need to go after the dealer that sold me the car, which is a scary thought for anyone who sells a Z06! If the Chevy dealership that serviced my car didn't know the car was flashed when they looked at the CPU for a software update, how was the dealer that sold me the car supposed to know (or myself for that matter)? I would strongly recommend anyone considering buying a used Z06 to somehow have a dealer check the codes in the CPU prior to buying the car as apparently that is the only way to tell, or would just steer away from them all together. Not only do I need to buy a new motor, but they are charging me for the tear down (about $1K). Anyone have any recommendations because I think this is total BS and could use some help? Thanks!

Granted the second one has suspension mods the MOTOR was still stock and so was the tune. Let's also not forget Joe's post.
So I will admit I had my timing wrong, there are still plenty of examples of cars blowing up stock.
