Engine Lubrication Description

The oil pump is a trochoid rotor pump that rotates with the crankshaft. The pump draws up oil from the oil pan through the oil pump strainer. The oil delivered from the pump flows through the oil filter.

The filtered oil flows through the two paths in the cylinder block.

Through the first path, the oil reaches the crankshaft main bearings. After lubricating the crankshaft main bearings, the oil is supplied to the connecting rod bearings by way of the passages formed in the crankshaft and then injected through the oil jets to lubricate the pistons, piston rings and cylinder walls.

Through the second path, the oil goes up to the cylinder head and flows in the passages formed inside the camshafts to lubricate them and the valve mechanisms.

The oil pump has an oil relief valve. The valve opens when the oil pressure exceeds the preset limit to release it.

Oil Pressure Check

WARNINGTo avoid danger of being burned, do not touch exhaust system when it is hot. Any service on exhaust system should be performed when it is cool.

Note. Prior to checking oil pressure, check the following. Oil level in oil pan If oil level is too low, add oil up to full level mark (hole) on oil level gauge. See ENGINE OIL AND FILTER CHANGE . Oil quality If oil is discolored or deteriorated, change it. For particular oil to be used. See ENGINE OIL AND FILTER CHANGE . Oil leaks If leak is found, repair it.

Engine Oil and Filter Change

WARNINGNew and used engine oil can be hazardous. Be sure to read "WARNING" in GENERAL PRECAUTIONS and observe what is written there. Steps 1) - 7) below must be performed with ENGINE NOT RUNNING. For Step 8), be sure to have adequate ventilation while engine is running.

Before draining engine oil, check engine for oil leakage.

If any sign of leakage is found, make sure to correct defective part before proceeding to the following procedure.
