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
