crank seal keeps going

[JohnFurness]

Why would a crank seal keep blowing? How do I fix this expensive problem?

two t hings. easily I'd make sure you don't have any burs on the crank that are wiping out your crank seal. and two check you PCV system, i've been down that road the hard way.

PCV def check. How sure are you of your installation? ie, are you pressing it far enough in? They can be pretty tough to get in all the way at times. I couldn't press mine in by hand I actually took a PVC pipe with an end cap on it the same diameter as the seal and pressed the pvc pipe up against the seal by tightening down the crank bolt.

Visual inspection of sealing surface?
