I pull around 10" of vacuum showing on the vacuum resevoir gauge, just enough to keep the PB functional (could be better). I don't believe I really have enough to run a traditional PCV w/o loosing more vacuum.
Misting isn't really bad, but I do get a little vapor (when running hard) around the vents as they are vented on the bottom. Is there any vacuum created at the air filter base (I would think much, but how much do you need for the crank case gasses to escape efficiently?).
Would like to have a clean and efficient engine
