For you drag racing guys, here's my problem. I have a 411 B&M Blower on my Ford 289 and it is leaking oil out of the case filler nipple onto the intake manifold and down the engine. I have covered the nipple with a dress up hose leading to a blank stud on the carburetor to remedy the problem but I am leary about puting a plug on it or blocking it in any way. It only leaks out the nipple while under power on the feeway at higher speeds (and higher pressure no doubt). I just put the blower on a few weeks ago and don't know if I am missing a valve that covers this nipple or if the case will eventually find a neutral level and stop leaking. Perhaps it is overfilled? Please see photo for clarification. I can take more pictures of the nipple absent the dress up hose if needed. Any and all help would be GREATLY appreciated as blower knowledge seems to be sparce in my area.
