Re: PCV question
The PCV, as I understand it, allows flow from the crankcase to the carb/intake to reburn blowby gases and any fuel condensation. It also will act as a check valve in case of a backfire in the intake, thus preventing a fire or explosion in the crancase. Anyone who has ever seen the results of this understands the importance of this function. I once saw an old Oldsmobile on which the owner had installed an electric fuel pump between the tank and defective mechanical pump (too lazy to bypass the bad pump; hey, it ran) The crankcase filled with fuel and when it went off the valve covers left dents in the hood and the oil pan was blown almost flat. Not pretty.
