Can you just do 1 cylinder ?

Just curious, what caused the original damage?

Don't know. The scrapes are on the sides (not top and bottom) of the piston. This one even showed good compression results, but i assume this was due to all the oil running into the cylinder from the valve guides. I think it was masking the leakage. Leakdown was high though.

Has any of the professional engine builders here offered their advice yet ?
