Default LS7 Valve Guide Issue

Looking for some feedback....My question is, I have a 2012 Z06 (25k's) that has full extended factory warranty until 2021 or 60K. I'm not having any valve issues as of now however wanted to know if this issue is something that is covered under warranty. If so has anyone had the dealer replace / repair under warranty?

Look forward to hearing from anyone's experience.

Any info would be appreciated.

If you have the Powertrain warranty, dropping a valve is definitely covered. When I had my 2011 Z06 I extended my warranty because of the valve issue. Before your warranty runs out I would get the valves replaced. Add a mild cam upgrade your looking at $4k.

I'm sure if you do some digging in the Z06 forum, you'll find guys that have had heads replaced under warranty, BUT, I'm assuming those are the squeaky wheels who have a good rapport (or stir up a lot of bs) with the service dept. Chances of getting heads replaced "proactively" (worn, but not "failed") are probably slim.

If the engine fails while you're under warranty - 100% - should be covered. I had an engine replaced under extended warranty - no hassles.

Once your warranty runs out? Just get the heads done. Depending which route you go, you'll be ~$3k +/-.

Your extended warranty isn't going to cover the work for a dealer to "check" your guides/valves for out of spec tolerances. Granted if you insist on a dealer to pull the heads to check them and they are out of spec then it is possible for the extended warranty to cover the fix but if they are in spec (even on the wide tolerance scale) you will be forking out the cost for the dealer to do the work to check your heads.

So basically if you still have extended warranty that covers a major engine failure don't worry about it. Yes I know it sucks thinking that you could have a blow up and even worse if it happens after your warranty is done but odds are you should be good.

My heads were done 3 years ago by AHP and so far so good on my LS7.
