front crankshaft seal blew out of nowhere. they put a new one in and that one blew immediately. what could be causing this?
(2) Answers
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

Excellent information autoknowhow! I'm assuming this is a technical service bulletin? Can you please post the TSB# if it is indeed a bulletin? thanks!
