GTO Dan,

Thanks for the great data. This is the same pump I purchased for the same reason - oil leak control.

Any more info on this vac pump situation? I am trying to solve a oil blowing problem on long WOT runs. A vac pump seems like a definite fix, but I want to make sure it is good for a street car. Seems to me like just a small amount of negative pressure would be all you would need to maintain to control leaks and be better that a stock PCV system.

Could you convert a vacuum pump to use an AC Compressor style clutch? You could have a valve or two (maybe an idle air control valve) that opens the system to just vent while cruising on the street, then use a RPM switch or WOT switch to shut the valve and apply the clutch to pull vacuum?? I have no idea how to do this, but it works perfectly over here in Fantasy Land
