hey just wanted to get some info for what people are using for a check valve when gutting the pcv valve. car started smoking on stock downpipe (muffler/res delete) and want to get is resolve before i install my downpipe. so basically two questions really.. what check valve are you guys using for non-upr catchcans and a pvc valve is pretty much a check valve so what is the difference between gutting it and pulling a check valve on the output of the catch can? stock diameter too small? catch can volume solves issue?
