Here, you are looking at the Killer B Motorsport Oil Control Valve. This product has been designed specifically for race use only and has been intended for boxer engine cars that will sustain +1.5Gs consistently. Under high-speed cornering and lateral forces, this device will help prevent oil from flowing out of the valve cover ports which will help keep the oil in the sump. Otherwise, oil could stay on one bank of the engine long enough to starve internal components which can lead to engine failure. This is another great measure to provide your engine with extra protection by providing adequate lubrication. 

 

DETAILS:

• 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
