Dorman 264-903 PCV Valve Engine Oil Separator

The Dorman 264-903 is a direct replacement Positive Crankcase Ventilation (PCV) valve designed to restore proper crankcase pressure regulation in your engine. The PCV valve plays a critical role in the emissions system by directing harmful crankcase gases back into the intake manifold for reburning, reducing emissions and preventing oil contamination.

Key Features:

• Direct replacement for worn or failed factory PCV valve
• Helps maintain proper engine vacuum and performance
• Prevents oil leaks caused by excessive crankcase pressure
• Reduces harmful emissions and oil sludge buildup
• Rigorously tested to ensure reliable operation and durability

A faulty PCV valve can cause rough idle, increased oil consumption, oil leaks, and reduced fuel economy. Replacing a worn PCV valve with this Dorman unit restores proper crankcase ventilation and helps your engine run cleaner and more efficiently. Installation is straightforward and typically requires no special tools.
