Was the crank flange checked for runout and/or damage on the seal surface? Was the seal installed with some lubrication so it didn't burn up on the first start up?

Checked the PCV system isn't blocked causing the crankcase to pressurise?

Was the whole seal and plate replaced or just the seal?

Check the land on the crankshaft that the seal runs on.
