Blow-by gases can mix with oil vapors in your crankcase, contaminating your oil and creating sludge. Your positive crankcase ventilation (PCV) system gets those gases out, recirculating them for combustion. The system may need a source of fresh air, preferably free of dirt and debris—that’s where the valve cover breather comes in!
