I just picked up an engine to rebuild. (link to for sale thread here http://dsmstyle.com/forums/showthread.php?t=16256 ) I just pulled the crank and found a spun rod bearing. There's some slight scoring on the crank. The rod is smooth in the center, but the outside edges are a little chewed up (kind of rough, but no deep gouges). I'm looking for advice. Since it was recently rebuilt I had hoped to only mess with the bottom end and leave the head on and in tact. Not sure if that's possible now. So:

1: Do I need a new rod or since it's just on the edges can I buff the damage out or leave it (and thus avoid pulling the head)

2: What should I do about the crank? Can slight scoring just be buffed out or would it need to be bored? If so, is it better just to get a good condition crank?
