The lubrication system includes a metal oil pan with an oil pick-up, which is bolted to the oil pump housing and sealed with a gasket.
The oil pump is installed at the front of the cylinder block. It draws oil from the oil intake through the lower oil line in the cylinder block. From the pump, pressurized oil flows through the upper oil line in the cylinder block to the right side of the engine, where the oil filter adapter with oil cooler is located.
The oil filter adapter with oil cooler is installed through a gasket on the right side of the cylinder block. Oil flows through the bottom channel in the oil filter adapter and through the oil filter. The filtered oil is returned to the engine block through the upper channel of the oil filter adapter.
Through several channels in the front of the cylinder block, the oil is directed to the cylinder head, as well as the channels of the main bearings and the oil nozzles of the pistons.
Channels in the cylinder head supply oil to stationary hydraulic valve lifters and camshaft main journals.
The channels supplying oil to the main bearings of the crankshaft also direct oil to the jets to cool the pistons. Each oil jet is installed between adjacent cylinders and directs oil to the piston skirts to cool them.
The oil returns to the crankcase through channels in the walls of the cylinder block and head.
