Overview Use this plug to delete the secondary pressure relief valve present in some LS oil pans.

The secondary pressure relief valve can sometimes get stuck, causing oil pressure issues. Typically, the secondary pressure relief valve may be deleted if

Active Fuel Management (AFM) and Variable Valve Timing (VVT) have been deleted and the oil pump has been swapped to a standard volume oil pump

Kit Includes: x1 Aluminum alloy M14x1.5 plug, x1 Crush washer

Vehicle Application Details Certain LS-based vehicles such as the 4th Gen Pontiac GTO, Pontiac G8 and 5th Gen Camaro feature an M14x1.5 pressure relief valve inside the oil pan. This valve is used to bypass excess oil pumped by the high-volume oil pump when Active Fuel Management and Variable Valve Timing are not active.

For those who have deleted AFM/DOD and have installed a standard volume oil pump, the pressure relief valve may generally be removed and plugged. Part no. 814-M14-KIT comes with a M14x1.5 plug and crush washer to ensure a proper seal.

Note: Removing this valve is not recommended for engines that have a high volume pump. The high volume pump must be replaced with a Melling M295, 10295, 10296, or similar pump to safely eliminate the pressure relief valve in the oil pan.
