Default Re: PCV valve for my H six ?

Gary, I like your plan for routing. I "reversed" the airflow of my 8CM V8 and installed the pcv in the oil fill/vent standpipe. I removed the road draft tube and used a small motorcycle oiled media filter (K&N)to filter incoming air. My thought was to draw the air into the pcv at a high point where the water vapor and heated crankcase fumes will tend to collect. So far, and 3 years later with 20,000 miles on the engine it has worked perfectly in all seasons with no sign of any condensation or sludge in the engine. No cab fumes either.
