main oil gallery. Oil in this gallery is divided into two passages. In one passage, oil is pumped to the crankshaft
main bearings. Oil is supplied to the connecting rod bearings through intersecting passages drilled in the
crankshaft. Piston cooling jets in each cylinder provide additional piston cooling and lubrication. In the second
passage, oil flows to the cylinder head to lubricate valve train components.
After passing through the cylinder block and cylinder head, oil is returned by gravity to the oil pan. Those
internal parts that have no direct oil feed are supplied with lubrication by either gravity or splash from other
direct feed components.
