The material redeposited on the piston crown?
What was the object?
Where is the object?
FOD ingestion is usually isolated to one (maybe two) cylinders.
Dude, it's for cookie... Read the comments.
to unify theories, the staple or cookie may have damaged the area in a few cycles and then was blown out, which caused hot spots that focused detonation damage in a local area.
'C' denotes the piston diameter. Have to dig it up from a green book. Bentley manual has the chart included IIRC.
'Tis not a staple
I've already chided the firat person to miss the joke.
That... is a pit.
Too much focus of appearance of damage versus distribution.
Discount FOD because of impossibility of the marks being limited to one edge of a piston.
Taking the violence of the surge of intake and exhaust between the explosions of combustion, try to envison a foreign object repeatedly only damaging the same area, and not bouncing out anywhere else.
Unlikely.

My detonated pistons looked pitted and grainy, but maybe forged pistons damage differently?
Has not been helicoiled. Going to check spark gap tomorrow (working late tonight). Think these we're ngk 6s?
