Oil Pan

The structural rear-sump oil pan is cast aluminum. Incorporated into the design is the oil filter mounting boss, the active fuel management oil pressure relief valve and the drain plug opening. Filtered oil is returned to the engine block through the oil filter to the engine block upper oil galleries. The press-fit oil pressure relief valve is located at the left rear of the oil pan and can be inspected by removing the oil pan cover. The alignment of the structural oil pan to the rear of the engine block and transmission housing is critical.
