I am writing to you on behalf of all C6 Z06 Owners here at the Corvette Forum. There has been way too many C6 Z06 owners that have suffered LS7 engine failures due to dropped valves. GM claims that there was a manufacturing problem that was subsequently corrected, yet engines and off the shelf replacement cylinder heads produced after that date are also failing at an alarming rate. Loyal owners of even extremely low mileage vehicles are continuing to measure valve-to-guide clearances far beyond service limits and have had their heads reworked at a significant cost. This is evidenced by a cross section of Corvette Forum Members who have had their valve-to-guide clearances measured, 88% of the 208 member cars checked have had out of spec valve guides on C6 Z06's built from 2006 through 2013. With the apparent widespread incidence of excessive valve guide wear among LS7's, does GM know anything regarding the root cause of the issue and/or potential mitigation actions in order for LS7 owners to regain confidence in the platform and to retain loyal GM Customers?

We look forward to your answer on this critical issue.

Really annoying that there is significant concern for a forced induction car to overheat...in the light that so many C6Z owners have to tear into a handbuilt engine to fix something that GM got wrong, or risk BLOWING THE ENGINE!

Cooling is a common concern for FI cars, which is a really good reason to avoid tracking a FI car...

I voted for the LS7 exhaust valve issue and would love to finally have someone at Chevrolet give a definitive answer.

Thank you for creating this section!

Looks like we are way ahead so far... I have to admit, while I'd love to hear what he has to say about this, not being able to get parts for a C5 is pretty deserving of an answer. I think we are second in line!

I realize this poll is closed & I'm late. But I vote for this to be answered, too. I only started learning about this issue recently. It's got me plenty scared.
