This has been an ongoing issue with this blower for a number of years. What's happening is that the output shaft seal is leaking hot compressed air into the housing, which causes the oil to plash upwards. The only real solution I've seen to this was to plug BOTH sides, since it is a self-contained unit.
Edit: Rusty's idea sounds pretty good imo.
