Overview

The ACDelco CV774C is a PCV valve designed as an emission control component. It is a GM-recommended replacement part for your vehicle's original factory component, offering the same performance, reliability, and durability expected from GM OE parts. This valve controls the volume of crankcase vapors drawn into the intake manifold, and a restricted valve can lead to oil leaks or increased oil consumption.
Show original supplier description
The ACDelco CV774C is a GM Original Equipment Positive Crankcase Ventilation (PCV) Valve, designed to meet the same standards as the original component in your vehicle. As a critical emission control part, the PCV valve regulates the flow of crankcase vapors into the intake manifold. A properly functioning valve is essential for preventing issues such as oil leaks, excessive oil consumption, and sludge formation, which can degrade engine components over time. This PCV valve features a push-in mount type and a 90-degree nipple direction, with an outlet end outside diameter of 0.339 inches (8.6 mm). It is manufactured to GM Original Equipment specifications, ensuring it fits, functions, and performs like the original part. ACDelco’s GM Genuine Parts are a reliable choice, offering the quality, reliability, and durability that GM OE parts are known for. PCV valves are considered maintenance items and typically require replacement every 30,000 miles, though it's always best to consult your owner's manual for specific service intervals. Common symptoms of a faulty PCV valve include oil leaks, oil in the air filter housing, increased oil consumption, gray-white smoke from the exhaust, or the illumination of the Check Engine Light with codes like P0171 or P0174. A simple diagnostic tip is to remove the valve and shake it; if it doesn't rattle, it may be clogged or dirty and require replacement.
