Improved Racing LS Oil Pan Pressure Relief Valve Plug Kit
$7.59
- 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
- The oil pump has been swapped to a standard volume oil pump
Certain LS-based vehicles 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.
Includes
- Aluminum alloy M14x1.5 plug
- Crush washer
