Engine Oiling System: Notes

Oiling system is force-feed type and uses a full-flow oil filter. Oil pump is driven directly by crankshaft. Oil is retrieved from oil pan by oil pump pick-up tube and distributed to oil filter. Oil is then filtered and routed throughout engine. Turbocharged engines have oil spray nozzles mounted in cylinder block. Oil is sprayed up inside pistons to aid in cooling and prevent detonation.
