Oil Pan

The oil pan is mounted to the bottom of the cylinder block. The oil pan houses the crankcase and is made of aluminum.

Engine oil is pumped from the oil pan by the oil pump. After the oil passes through the oil filter, the oil is fed through 2 paths to lubricate the cylinder block and the cylinder head. In one path, the oil is pumped through the oil passages in the crankshaft to the connecting rods, then to the pistons and the cylinders in the cylinder block. The oil then drains back into the oil pan. In the 2nd path, the oil is pumped through the oil passages to the camshaft. The oil passes through the internal passageways in the camshafts to lubricate the valve assemblies in the cylinder head before draining back into the oil pan.
