I am investigating a vacuum pump based crankcase evac system. I am currently running a Moroso header bung vacuum system that works up until 5000 rpm or so. Above that, oil mist starts coming out of various locations, mainly the oil dipstick. I put a spring on the dip stick to keep it from fly out after a few WOT redline pulls. The previous PCV system was a total mess, so the header vacuum bung setup did help, but only under cruising conditions.

I am running A/C, Power Steering, and and Alternator off the motor right now which does not leave much room for a belt driven vacuum pump. Any ideas? I have been looking at the Moroso, Aeromotive, and GZ pump systems. Any comments? I would much rather run an electric vacuum pump b/c of space, but cannot find anything on them.

 

None of you turbo or blower guys have evac problems?

 

Might try the late-model forums, and the racing/autocross guys over at the Corral Forums.

I'd be interested to hear your final solution, though.
