i have a leak from then air / oil separator box on my R. happened after i installed my blower. does the box ever go bad? i am gonna check it when the engine cools, may be the O ring ... kinda stinky, and it's quite a bit of oil (a few teaspoons after a couple hour drive) drips right onto the halfshaft and onto the header collector. stinkY! just seeing if anyone else has had a leak from that area before.
