New OE 1974-1981 & 1985-1987 Corvette PCV Valve. Positive crankcse ventilationFits 1974-1980 L48 & all 1981 Corvettes. Mounts in valve cover.
Engine rotation builds internal pressure that must be vented. Early Corvettes used road draft tubes for this ventilation, later models used positive crankcase ventilation or PCV Valve. The PCV valve is connected to a filtered air source and supplies clean air to the crankcase. The PCV valves regulate the amount of air flow, which helps reduce oil consumption. Faulty valves can increase oil leaks via negative pressure AND cause the natural moisture (from condensation) to build up in the crankcase which can greatly reduce engine life.
Check your valve cover grommet when installing a new PCV valve. Cracked, broken or leaking grommets can reduce the proper function of your Corvette's positive crankcase ventilation system.
