Vacuum pumps
Anyone on the list running a vacuum pump?
As in a crankcase vacuum pump.
As you know I'm running a supercharger.
I'm still fighting oil seal leaks.
Putting PVC valves back into the system cured my leakage issues when not under boost, but the second I hit boost the leakage starts.

Well I've been looking a vacuum pumps for CCV but they are not cheap, and take up a lot of room. Converting the Ford escort AIR pumps is an experiment but something you can read about on a search.
I see you are running a supercharger Brian. When I was curious as to how the new S/C LT4's handle crankcase ventilation it looks like they use a check valve that allows the regular PCV to operate until the boost becomes positive and then the crankcase is connected through the lifter valley to upstream of the supercharger which has enough suction/lower than atmospheric pressure to pull from the crankcase. I think the new turbo cars use something similar. You can google supercharger/turbocharger crankcase ventilation and look into this yourself.
Hope this can help.

Just a reminder the car is supercharged
3/4in lines on the PVC
It's a built engine
Lunati Crank SCAT pistons & Rods, AFR heads.
BTW even with a lumpy custom blower cam it still pulls 14in of vacuum at idle.
No smoke out the exhaust
