SYSTEM OPERATION
The schematics above illustrate the engine oil lubrication system. The arrows indicate the flow path of the oil. The lubrication pump draws oil from the pan and forces It through the lubrication system. The pressure regulation valve controls the oil pressure In the system The filter bypass valve ensures a supply of oil in the event the filter becomes plugged. The piston pins are lubricated by the splash from the piston cooling nozzles. The oil pump idler gear bushing is pressure lubricated. The remainder of the front gear train is lubricated by oil carry-over and splash.
