Mark200X and Kneel 8250, Would you like to make a friendly little bet. I bet $100 that the exhaust valve will have lost its head. I don't know anymore information other than what is in this thread. Want to call my bet?

Point to me where exactly I said that the exhaust valves were intact.
I offered a different opinion from what was being expressed based on my experiences.

Well I am going to disagree with everyone else and tell you that spark plug is a classic pre-ignition case. You have a tune on your car and a fresh tank of gas. It seems to me that you burnt a hole in the piston so things probably wont be as dire as some are predicting.
Unfortunately if I am correct it does mean work.
Hope I am wrong and you can salvage without too much expense.

I do not believe that you will see that kind of physical damage on only ONE plug from detonation. I would think there would have to be some evidence on other plugs. I still say it is the result of a broken exhaust valve.

Oh you'd be surprised. I ain't saying that's what occurred, but it is a possibility. At this point, it's just a guessing game and a bunch chest thumping.
My condolences to the OP, regardless. ANY engine failure sucks.

Shedding a tear isn't getting us anywhere either. (I already tried that when I looked at my empty wallet) I think we are already/have been at the fifth stage of grief.

Thanks for all of the positive words. I will get around to taking the head off this weekend. I looked for the link on the forum on how to take the head off. I am still pissed that I have to do all of this or take it to a shop to have the heads and or pistons done.
Like I said before. I have sprayed nos on a 91 Z28 350 with a tune and cam on 93 and ran the car as a daily driver with no heads work and the car is still here running. No engine or head problems. Did the same with my LS1 with a tune and it ran 99k miles before I sold it and the engine was solid. My 03 SVT Cobra had the tune, pulley change, x, CAI, cats, and cat back. Never a problem. My Z06????????????????
I have the most powerful GM engine hand built LS7 by E.L. Richards from Wixom Performance Build Center in Wixom Michigan. So you are going to tell me a tune killed my engine on a fill up on 93? Everyone fill up on 93 with a tune. I would say wow. I was not even in it Kneel 8250. All the other plugs are perfect. We would have a tone of folks running from tunes. I think it was the build. I heard of the dropped valve on the Z06. Didn't think my 06 was affected based on the post. Paid toooo much to have a bad engine from GM. I got the car last year and only put less than 2k miles on it. Sold my C6 vette with 17k to upgrade to Z06. Just a weekend play car no rain or track never. Like I said before, I have a drop line ready Z. Now it is drop line ready Zwith a bad head / engine. Wanted the best bang for the buck. Guess I should have kept my SVT Cobra. That was the best bang for the buck b4 the Z came out.
My car failed the same as the others Z's on here. I have internal damage. That means pulling, rebuilding or replacing the LS7. The car will still need to be towed and inspected by a LS7 specialist. Money, Money, Money!!!! GM will do nothing for me tune or not. If that was the case everyone else would have gone to GM and they would have helped them. GM will not pay 15k to replace every ones dropped valve engines. They want money like all the other stealerships.
I will get the head pulled. If I have to do this it still means I have bad engine period.

If you have or have had worn valve guides, file a safety complaint here:
https://www-odi.nhtsa.dot.gov/ivoq/
Or here http://www.safercar.gov/
Indicate the date you found the wear and that this can lead to catastrophic faulire of engine causing danger to you and those on he roadway around you due to :
engine lockup --> loss of control of the vehicle
fluid spillage --> potential fire, road hazard
large smoke cloud from exhaust --> impair drivers around you
There are currently 1 complaints for a 2006 valve drop and 2 complaints for a 2007. It takes 5- 10 to get their attention. The roof recall for 2006 took about 8 complaints.

I am a lucky Z owner. Finally got my car on the road. I only needed a head job. The block and piston were ok. The valve did cause the problem. Got good deal on a set of WCCH heads from one of my friends that sold his Z. He had a unused set of heads he was going to put on his project car. He needed the money and I gave him my heads and some cash.
Thanks for all the help guys!
