Engine Lubrication - Operation

OPERATION

The oil from the oil pan is pumped by a gerotor type oil pump mounted to the front of the cylinder block that is part of the oil pump housing. The oil from the pump travels to the oil cooler assembly and then to the oil filter element. After the oil has been filtered and cooled, the oil enters the main oil gallery. The pressurized oil travels through the main gallery to the five main journals to lubricate the crankshaft main bearings and supply oil to four piston oil cooling jets. The pressurized oil travels through the crankshaft main journals to cross-drilling supplying oil to the connecting rod journals. From the cylinder block the oil flows into the cylinder head. Cylinder head oil is supplied to the camshaft journals and hydraulic lash adjusters. Oil also flows through a filter screen and into the variable valve actuation assembly to open the intake valves.
