I have a BX2200 330 Hrs. it started leaking oil up in front by the flywheel I assumed it was the rear seal which is actucally in the front, but when I removed the flywheel oil came out of one of the bolt holes which holds the flywheel to the crank I wiped out the hole and it looks like all the others. Why would it be leaking oil through the crank or am I just imaging things, the seal itself looks good and as wet as the flywheel is it almost had to be coming from the center of the crankshaft itself.
