Thanks for that Charles, very interesting read on PCV.
I currently only have one side of that equation with only vacuum when punching it, I would love if I could find a similar setup like that but going the AN route, I think for that I would probably throw check valves in each of the lines and have a -10 or -12 into the intake plenum. I would prefer that route cause not a big fan of all the lines he has running in those pictures.
