Q:what's the purpose of this product?
A:With reference to inquiry on the Beck/Arnley PCV Valve - Part No. 045-0352, the purpose of the PCV valve is to regulate the flow of crankcase fumes into the intake manifold where they can be burned. It also has a secondary role as a check valve, to prevent flow back into the crankcase. This prevents potential ignition of the crankcase fumes, should the engine backfire. The PCV system is also crucial to proper engine sealing. The system alleviates crankcase pressure, which can push out on seals and gaskets, contributing to oil leaks.
