After getting some good advice from Oliver I got the engine removed and pulled the oil pan to discover major damage to the piston, rod, and both balancing gears, something obviously came apart and it was down hill from there.
At this point I am looking at the crankshaft and the rod where it attaches to the crank and find what appears to be melted metal on both surfaces which, based upon other engines I have seen, would indicate a problem with the bearing, however in all of the research I have done I am unable to find any reference to a bearing. Does this rod have a separate bearing or is it simply a machined surface?
A follow up question then, is there any way to refurbish the crank without having to remove it or am I looking at a throwaway and full replacement of the crank, rod, piston and gears?
