It is unlikely this is related to any looseness in the balancer shaft bearings, but it never hurts to check. Ordinarily, such a problem would manifest itself as a coolant leak before oil showed up.
Replace both seals while you're in.

You'll need to drain the coolant and the oil. The clutch cover can stay on the crankcase cover, although the top two bolts run all the way through to the crankcase, so they have to be removed. Remove the right side crankcase cover, hold the impeller shaft by the flats ground on the fat part near the bearing (13mm) and unscrew the impeller (tight, but a standard right hand thread: counterclockwise to loosen).
Note the seals. The larger, spring loaded sealing lips face up, out of their pockets, toward the fluid they control. This makes them look backward, but they belong that way. Check the shaft for grooves worn in by the seals, and also check the balancer bearing for excess clearance.
Normal parts would be both seals, a crankcase cover gasket, the shaft bearing, and possibly the shaft.
