Race car mystery-Help us solve PLEASE

You hurt a piston or a valve some where pull the heads and physically look . Happened to me car ran great sounded great but hurt a piston . Loosing that much time and power its serious . Just my opinion

I can't see that making it past a leak down test.
Did you do a leak down test on yours?

I only ask as he did, and it was good.


EDIT:
Sorry that sounded a bit snooty.:protest: Was just asking if something like that had past a leak down test.:D
