When I was circle track racing, we would do a crankcase vent similar to this. When we hooked it into the exhuast we would put a air diverter valve(remenber the old days of smog controls and air pumps) in line. This would act as a one way valve. It would allow vaccum to be drawn on the tube but no back flow. I'll be doing mine as soon as I install my 5" exhaust

Excellent confirmation regarding the induction of a vacuum in the exhaust. I had seen your setup months ago, but never knew about the "in and out" repeated trial that you jsut described. I'm more convinced than ever now that if/when I get to the point of enlarging my exhaust, I'm going to have my CCV routed in a simlar fashion as yours. Thanks for the details.
