CLICK for Definition?

This product has been designed specifically for race-use only and has been intended for boxer engine cars that will sustain +1.5Gs consistently.


- Prevents oil flow out of the valve cover ports based on the lateral forces placed on the car
- The design has been successfully used in aerobatic aircraft and the design is suitable for lateral loading
- Under straight-line acceleration, braking and moderate cornering the PCV vents work just as they normally would, letting blow-by gasses vent from all ports
- Under severe lateral loads, the port from the surging head is closed not allowing oil to pass into the AOS or catch can setup
- The balance ports and remaining head and crankcase ports still operate as normal
- Assures blow-by gasses only are permitted through the PCV ports


- Inlets are both 3/8 NPT
