7.
Check for wrong dipstick or guide tube.
8.
Talk to operator and check for sustained operation at light loads.
9.
Check for engine oil with incorrect viscosity (WP 0020 00). Engine oil with a thin viscosity can be caused by fuel leak-
age into crankcase or by the increased engine temperature. If suspected, refer to Increased Engine Oil Temperature
Inspection in this work package.
INCREASED ENGINE OIL TEMPERATURE INSPECTION
0010 00
N OT E
Oil temperature may be higher than normal when the engine is operating. In such a case, the oil cooler may
have a restriction. A restriction in the oil cooler will not cause low oil pressure in the engine.
1.
Look for a restriction in oil passages of oil cooler.
2.
Determine if oil cooler bypass valve is held in open position. If so, replace bypass valve (WP 0027 00). This condition
will allow oil to pass through valve instead of the oil cooler. Oil temperature will increase.
