Left rail, worn through a little at the base there, Makes you wonder what extended intervals on minerals would do to this engine!. I can see some wear on the load side of crank and cam sprockets,very little on the idler.
Couple of shot's inside...amg cast into the underside of the piston,weights added to the crank for proper balance.
Other parts to be replaced will be the tensioner(didnt hold oil well) and the oil pump check valve,which had drained dry.
