Fram Positive Crankcase Ventilation PCV Valve

The Fram Positive Crankcase Ventilation (PCV) valve is a replacement emissions-control component. It regulates the flow of crankcase vapors, also called blow-by gases, from the engine crankcase back into the intake manifold so they can be burned in the combustion process. A working PCV valve helps keep crankcase pressure under control and supports smooth engine operation.

Key Features:

• Controls crankcase ventilation: meters vapor flow according to engine operating conditions.
• Supports emissions control: routes blow-by gases back through the intake instead of releasing them to the atmosphere.
• Helps protect the engine: reduces pressure and moisture buildup that can contribute to oil contamination, sludge and leaks.
• Trusted brand: Fram is a well-known maker of filtration and engine maintenance products.
• Direct replacement design: intended to replace the original PCV valve in a routine maintenance service.

Replacing a worn or clogged PCV valve at the recommended service interval helps maintain engine efficiency, idle quality and long-term engine cleanliness. A failing valve is also a common cause of rough idle and oil consumption. Also known as a PCV valve, crankcase ventilation valve or emissions PCV valve.
