Might look into what could be causing high crankcase pressure in the first place. Excessive blowby, etc... I dont have exp with this specific engine, but from past exp it could also be the recess for the seal is out of round, or maybe the crank is nicked and destroying the seal.

Some shops dont look for root causes and only fix the symptoms.... which leads to recurrence. Given the number of similar but different issues, might be worth doing a compression and/or leakdown cyl test.
