Engine Oiling System: Notes

Oil is circulated through engine by pressure provided by a trochoid rotor type oil pump. Pump is mounted on bottom of crankcase and inside oil pan. Pump is driven by camshaft via distributor drive. Oil is drawn from oil pan and circulated through a full flow oil filter and into main oil gallery. Oil is then distributed to main and connecting rod bearing journals and camshaft journals. Cylinders and piston pins are lubricated by oil spraying from hole in crankshaft end of connecting rod. Timing gears are lubricated by oil squirting from hole in crankcase next to gears. Oil flows from number one camshaft bearing journal to rocker arm shaft to lubricate rocker arms. Excess oil from rocker arms and shaft lubricates valves.
