Achieving maximum fuel efficiency while reducing emissions on your car or truck depends on your use of properly functioning exhaust and emissions parts. The engine in your Audi S4 gives up some efficiency and emissions, and it uses a PCV valve to control its positive crankcase ventilation. Almost always mounted above your cylinder head in the valve cover, your Audi S4 PCV valve captures and re-routes exhaust blow-by from the combustion process and sends it back through the intake. Before the positive crankcase ventilation valve, all blow-by was simply vented through a small filter element in the valve cover. This is a much cleaner method.
