Oil from the vent

[Andy Cost <andycost@earthlink.net>]

I've always wanted to do the negative crankcase pressure trick ala NASCAR.  
They sell a kit at www.summitracing.com
It has a tube with a valve at either end.  One end welds onto the exhaust 
manifold and the other onto the valve cover.  Drawing a vacuum on the crankcase 
increases piston ring seal and raises the compression in the combustion 
chamber.  It also reduces oil foaming in the sump which decreases windage 
associated drag.
