haha good luck with that then. urs must still be in warranty then lol. go visit any big reputable LS shops and see how many dead LS7s they got on the floor and tell me if its internet based hype or not. funny thing is when i sold my stock ls7 short block online i had about 15 ppl wanting it cause there z06 dropped a valve or split a block. they all band wagoners and gossips aswell or are they real life examples of ppls ls7s going splat??? i enjoy driving my z06 too but just cause i own one duznt mean im going to defend GM for shoddy work they did building the engines.

Are u on crack? Im not talking wiggle test. I'm talking broken engine with cracked pistons n blocks from dropped valves. Why did 10-15 ppl call me bout my short block?? Broken engines not failed wiggle tests. U keep talking in circles and avoiding every fact I bring up. Chev will never let the public know how many ls7 engine were replaced under warranty plus how many were rejected cause they were modified. It woyld destroy the reputation to admitting fault. Like talking to a wall dude. Let me guess...ur ganna ask for the 15 x how many ls7 engines failed??? N ignore everything else said?? i PERSONALLY, not over the net, PERSONALLY kno 3 ppl had replacement engines fitted and i only know im guessing 12-15 ppl with a z06. they all band wangoners making **** up on the net aswell??

I think I'm out on the ls7 thanks for the tips guys just too much to pay just to sit and worry about my low mile ls7 having issues..GM needs to get their act together.

For the same money u can get a 2009-2010 or so zr1. Better forged n supercharged motor, better gearbox, better brakes, better everything! Wait a few more months till the new z06 comes out n these will be a lot cheaper again

Yea....I can see the dealer now...."So you want new heads cause your warranties about ready to run out?....well heck yes...bring it on in we can do that".......NOT !!

They have also acknowledged an issue with the rod coatings leading to some 2013 failures.
Sure they could - and should - do more, but maybe what they've done covers it, at least for bone-stock engines, and the problem is being blown out of proportion, who knows.

I do not have a Z06. I wanted one badly in 2008 but finances kept me from picking one up at that time. Now I'm happy I went with the base Corvette with the Z51 and LS3. 2 friends both have 08 Z06's. Both do track days but video all there runs. Both have blown engines and GM replaced with no questions asked.
In one case you could hear my buddy coming up to speed coming out of the pit and at ~3500 rpm, BOOM. The dealer figured it dropped a valve but we never heard back from the "GM Investigation of Failure".
My other buddy was driving to the track and heard a metal on metal noise and had his oil pressure drop to zero. He had it towed in and the dealer said the bottom end got oil starved for some reason.
Maybe it's just bad luck but I know 5 guys with Z06's and with 2 having had blown engines, that is not an average I'd be willing to gamble on. Both had less them 20k miles when they went south. YMMV

While there is some truth to the issue (I replaced my heads without doing any tests), most of it is amplified greatly by the Internet, and more specifically, these forums.

value drop, rod bearings, split block, cam bearings, failed oil pumps, worn cam lobes, lifter issues just to name a few issues with the ls7. kit kat engine. id never own one as a daily if it didnt have warranty. in 25 yrs in the industry ive never seen or heard of so many failure from factory unmodified engines more than the ls7 and they havent even reached 10 yrs old yet. heapsof failure stories with engines with only a few 1000 miles on em. hate to imagine what drama they will have in 10 yrs tym with the ones that havent shat themselves yet. id take any other LS engine just not the ls7.
The Z06 section has quite a discussion on some of these issues, the OP might want to have a look there as well.
