that is 1 one of 2 things (found that photo and what beauty it is )
sucked a valve and its chucks beat it to death
or rank detonation, (lean burn knock dmage )
i'd then take my trusty bore scope in to that 14mm hole and see piston top damage and even chunks.
or use the compression gauge, omg,,,,,,, 0 PSI.
omg it is magnetized and with fine iron filings, (valve dust ) it's got HAIR see it?
