Chevrolet Performance 25013759 BBC Oil Filter Bypass Valve
This is a new Chevrolet Performance 25013759 oil filter bypass valve for Big Block Chevy applications. It is commonly used on Mark V and Mark VI Big Block Chevy engines, including many 454 and 502 based combinations.
This factory-style bypass valve is designed to open at approximately 11 psi pressure differential. It is used in the oil filter pad area of compatible Big Block Chevy blocks to provide the correct bypass function in the oiling system.
Chevrolet Performance / GM bypass valves are commonly used during engine rebuilds, oiling system service, block preparation and when correcting or restoring the original oil filter bypass configuration on Mark V/VI Big Block Chevy engines.
Important Fitment Information
This bypass valve is intended for compatible Big Block Chevy Mark V and Mark VI oiling system applications. It is not a universal bypass valve for every Chevrolet engine or every oiling system configuration.
Factory assembled 454 and 502 Mark V/VI engines can use bypass valves in the oil filter pad area. Depending on whether the engine uses a stock filter location, oil cooler passages or remote oil filter setup, the correct bypass valve arrangement may vary.
Always compare the part number and oiling system layout with your engine build before ordering. For some racing, remote filter or oil cooler configurations, a different bypass arrangement or higher pressure bypass valve may be required.
