front crankshaft seal blew out of nowhere. they put a new one in and that one blew immediately. what could be causing this? -
Answer 1
Customer Concern: Front crank seal repeat failures, pushing out. Tests/Procedures: 1. Check crank case pressure (blow by) at wide open throttle. 2. Check and clean the drain hole in the oil pump housing at about the 6 o'clock position just behind the seal. Potential Causes: Excessive Blow-By Restricted Seal Drain -
