Hi everone, I had my flywheel cover off last night and when I turned it back and forth i could hear a knocking noise. When it is running there is a slight noise when idling but I can't hear anything when it is revved. I had the top end off a week or two ago and the wrist pin and crank rod bearings seemed to be good with no vertical play. Could this be "piston slap". And does this mean i have to replace the top end?
