Engine Oiling System
The engine oiling system is full pressure with rotary (sickle) type pump. Oil is picked up by pump through strainer and suction tube. Oil passes through pump and pressure control valve to oil filter and main oil channels. It is then distributed to main bearings, connecting rods and crankshaft. Camshaft lubrication is provided by spray tube at No. 1 cam bearing. Oil pressure switch is located at end of camshaft lubrication passage. A temperature sensor is located in oil pan.
