PCV Questions
What he is describing should have put his crankcase in a vacuum not pressure because he had a pvc valve but no way for filtered air to go into the crankcase. Unless the pcv valve was bad the other way and was blocked then the pressure would build up. I thinking in your senario, 64dartwagon it was probably going down the exhaust guides causing the white smoke and not blue smoke from being burned like if it went down the intakes. I'm thinking your right on the guide thing.
