I don't think so, but it would be nice, as I'm having seepage between
the seams off my crankcase, and would like that to magically go away as
well.
I don't really understand the mechanics of the centrifugal breather
valve fully, but it seems to be a mechanism to release crankcase gasses
while preventing oil from escaping. Even if the seal is not working,
the gases are still going to escape, perhaps more freely. In other
words, I don't think the seal going bad would cause the crankcase to
pressurize. But maybe I'm wrong?
Laters,
