A couple questions.
I took off a head for a friend last night assuming he had a popped headgasket. Turns out headgasket looks fine and the piston itself is ovaled on the front edge and I can see the rings . He was getting massive blowby but I didn't really put it together in my head until I saw the piston.
There is some scuffing of the cylinder wall.
How do I fix this? Can I pull just that piston, and put another used piston in there? I'm assuming I'd need to put a new bearing on the crank, do I need to put all new bearings? How do I get the light scuffing out of the cylinder wall?
