Need picture of sides of pistons looking at ring lands. You got all kinds of wacky angles. all ring land pictures are blurry. all I can determine so far is there was no scuffing on skirts. a couple of pics show possible detonation but are too blurry to tell. there is considerable darkness between lands for that mileage also supports this. if the top of piston is over heated from detonation it can pinch top ring from floating and score bore. then all ring seal would be shot. how do bores look?
