Standard Motor PCV Valves

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.

CVR Oil Accumulators

CVR oil accumulators keep an extra reserve of oil to help prevent engine damage from pressure loss. These accumulators use compressed air to force their oil reserve into your engine when the oil pressure drops below normal. They're plumbed directly into the pressurized side of your oiling system. CVR oil accumulators can be used as manually operated prelubing devices during start-up. Designed with threaded billet end caps for higher pressure, they have a 3-quart reserve tank and include mounting hardware.
