Bad ring? What would have cased that indentation right in the middle of the transfer..where the middle crack is? Is that a ring width? Seems like there's a matching mark on the piston, but who knows when in the cratering it all went down. A chunk of ring floating about then getting caught and pulled down would explain the transfer bridge getting pushed out like that.
Seems like lots of pointing towards port shape, etc, but if it's "milder" as Brad says then why would that be the cause?
Bad rings? Overly tight ring gap? Why did it crater when the throttle was blipped? I thought your typical ring hang was at low RPM's?
Just spoutin ideas...
