The Standard Ignition V156 PCV Valve is engineered to meet or exceed original equipment (OE) specifications, ensuring optimal performance and longevity in American vehicles. This valve plays a crucial role in the engine's ventilation system by regulating the flow of gases from the crankcase to the intake manifold, thereby maintaining engine efficiency and reducing emissions. Designed for a hose size of 1/2 inches (10 mm) with a straight nipple orientation, the V156 is compatible with a wide range of vehicles, including various models from Chevrolet, Ford, Mercury, and Pontiac, spanning years from 1964 to 1979. Its construction from high-quality materials guarantees durability and resistance to wear, even under demanding operating conditions. By replacing a failing or worn PCV valve with the V156, fleet operators can expect improved engine performance, reduced oil consumption, and lower emissions, contributing to the overall efficiency and reliability of their vehicle fleet. This proactive maintenance measure helps in minimizing downtime and extending the service life of the engine, offering a cost-effective solution for fleet management.
