I have replaced dozens of N55 oil filter housing gaskets. Never has one resulted in engine failure. The worst I have seen is an Intake vanos fault from debris falling into the solenoid oil port during cleaning. Pull the intake solenoid, clean it and fault is gone. Something else is going on, seems weird to me.
