Standard Motor Products replacement PCV valves are emissions-control devices that route unburned crankcase blowby gases back into the intake manifold where they can be re-burned. By totally eliminating crankcase emissions, the constant recirculation of air through the crankcase helps to remove moisture, which would otherwise cause sludge to form. Standard Motor Products replacement PCV valves will extend the life of the oil and the engine.

ACDelco Gold PCV valves are high-quality aftermarket components. The PCV (positive crankcase ventilation) valve controls the volume of crankcase vapors that are drawn into the intake manifold. A restrictive PCV valve can cause oil leaks or increase oil consumption. These replacements have been manufactured to meet or exceed your expectations for fit and performance.

PCV valve hoses transfer excess gasses from the crankcase to the PCV valve. If these hoses become faulty, the gas will not be transferred back into the engine, and your vehicle will be less efficient, with increased emissions and poor fuel economy. Motorcraft replacement PCV valve hoses are constructed of EPDM rubber for reliable performance in your crankcase ventilation system. These hoses are recommended by Ford Motor Company—and will resist heat, oil, grease, and other underhood additives. Choose the model designed for fitment on your vehicle.
