Piston is polished, guessing to 15/100 of mm clearance, must've been a lot of skirt slapping to form those cracks.
Intentionally skipped the damage pics, as eventually that is what happens, when cylinder wall, rings and piston are warn, so rings expand into exhaust outlet and cut into cylinder wall.

Bad deal dude? How'd the cylinder make out?
