Holley 302-102 Engine Oil Pressure Relief Valve Spring for Ford Car Godzilla

For certain applications, higher than normal oil pressure is required. Typically, the oil pan must be removed to change the pressure spring on an oil pump. The Holley oil system allows direct access to the spring through the access port on the bottom front of the pan. Holley high-pressure spring P/N 302-102 can be purchased and installed to increase oil pressure by approximately 10 PSI at higher RPMs. To change the spring, remove the port plug, spring, and plunger. In some cases, the plunger may stay in the port. Make sure when reassembling the plunger is on top of the spring and oriented correctly.
