My piston was hamburger meat on the top and I actually ran the engine for a good 20min after the seat dropped. drove it into the shop. When I later disassembled it, the whole skirt and actually most of the body were missing and sitting in the oil pan.
I can agree with that, very minor nicks are fine, but most of the time its not minor...
