58 panhead, rear of right side case. The machining around this hole suggests it is more than just an open vent to the outside world.
A pretty good slug of oil blew out of there when started after setting for a few weeks. I presume that the oil comes from normal sumping, but I've never seen it blow out like that before. Any advice would be appreciated.
