Copper Washer, Oil Pressure Relief Valve

Copper Washer, Oil Pressure Relief Valve

The oil pressure relief valve consists of an aluminum plunger with a heavy spring behind it. Access is through the 15/16″ domed cap nut beside the dizzy. Once this nut is removed to prevent oil leaks, it is always a good idea to replace the copper washer (6K431) under the domed nut.
