A pressure relief valve is a NC (normally closed) type safety valve which operates when system pressure increases above a maximum working pressure. The normally closed position is indicated by the arrow away from the center line. The dashed line indicates that the system pressure acts against spring force for valve actuation. The FE engine uses a gerotorstyle oil pump. It’s mounted to the front left corner of the engine block inside the oil pan. The distributor drives the pump through a 1/4-inch hex-ended intermediate shaft. A pressure bypass spool valve is integral to the pump, and a selective spring controls maximum pressure.

As oil temperature rises to approximately 180˚ F, the valve closes and forces the oil to pass through the oil cooler. The oil then returns to the accessory housing where it is routed through the oil filter adapter, the filter and then again through the filter adapter, accessory housing and finally into the crankcase.
