hmmmm....quite interested in possibly doing this! never knew about something like this existed (let alone that oil vapors get recirc'd). How much do one of these go for? & are they specific to the make/model of the vehicle? Or is it a generic catch can & just do the hoses how you ran them? another question (cause I'm full of them now ), these hoses just carry air through them (w/ the exception of the oil vapor), right?
