The PCV (positive crankcase ventilation) system is important for siphoning blow-by vapors that end up in your engine’s crankcase and routing them into the intake manifold so they can be re-burned in the engine. The PCV valve specifically is a spring-loaded valve designed to restrict air that is siphoned, and is important for your Chevy Truck.!
