NOTE: Too much oil consumption can also be the
result if oil with the wrong viscosity is used. Oil with a
thin viscosity can be caused by fuel leakage into the
crankcase, or by increased engine temperature.
Low Oil Pressure

ILOO001P
Instrument Panel
(1) Engine Oil Light
Before starting the engine, the engine oil light(1) on
the instrument panel will turn on when the key switch
is turned to the ON position. The light will turn off after
the engine is started and while the engine is running,
lidicating normal oil pressure. The light will turn on
during operation only when there is insufficient engine
oil pressure to properly lubricate the engine's internal
paarts.
If the oil light comes on, indicating the pressure is low,
check for the causes that follow:
1. Low oil level in the crankcase.
2. Defect in the oil pressure indicator light or oil
pressure sensor unit.
3. Restriction to oil pump screen.
4. Leakage at the oil line connections.
5. Worn connecting rod or main bearings. Worn gears
in the oil pump.
6. Oil pressure relief valve worn or stuck in the OPEN
position.
7. Oil filter bypass valve stuck open. Oil filter is
restricted. Replace oil filter.
High Oil Pressure
Oil pressure will be high if the oil pressure relief valve
in the oil pump cannot move from the closed position.
Too Much Component Wear
G424 Service Manual
5 6 7
When some components of the engine show bearing
wear in a short time, the cause can be a restriction in an
oil passage. A broken oil passage can also be the cause.
If an oil pressure check is done and the oil pressure is
correct, but a component is worn because it does not
get enough lubrication, look at the passage for oil
supply to that component. A restriction in a supply
passage will not let enough lubrication get to a
component and this will cause early wear.
