That could be causing the detonation. i hope so cause i hate to pull the motor if that was only the case.

if that piston is chipped toss that motor in the junk pick up a used engine swap it in there. the only way to rebuild these engines is to do so with lots of expensive machine shop work.


a used engine is the cheap way to go in the end. you'll spend way more rebuilding it vs a used engine.
