While in process of doing top end rebuild, I took the head off to see that the right side of the head was dinged up pretty good. Pulled the cylinders off and inspected the old pistons, rings, and jugs with no metal missing anywhere. The current spark plugs that came out where not missing any pieces either. Has any one heard of the spark plug tip breaking off? Also should I go ahead and split the case and make sure nothing is in the bottom?
PS The old piston has no damage to the top. Im thinking that the previous owner had something happen and replaced the piston with out touching the head? Any ideas welcome. Pictures available if needed.
