More info
The Radium Engineering 20-0683 PCV Valve is a universal PCV (positive crankcase ventilation) valve with a 10AN ORB inlet and 5/16" SAE Quick Connect Male outlet. Use it when the OEM PCV valve is removed, needs to move to the catch can outlet, or on engines without a PCV system.
Like an OEM PCV valve, the internal plunger dynamically meters crankcase vent airflow based on engine load. A proper PCV valve prevents the vacuum leak a check valve would create at low loads, closes during an intake backfire so combustible vapours cannot ignite in the crankcase, and closes under boost on turbocharged and supercharged engines to stop intake pressure entering the crankcase.
Key Features
- Dynamic metering — plunger meters vent airflow to engine load
- Boost and backfire protection — closes under positive pressure
- Construction — 6061 aluminium, Type-II anodised, FKM/silicone O-rings
- Ready to fit — supplied fully assembled with a 10AN ORB FKM O-ring pre-installed
- Catch can compatible — fits all Radium catch cans
