Remedy:
Change oil. Use specified oil.
Change oil filter. Clean oil cooler, replace if
necessary.
Note:
At low ambient temperatures the oil may be
overcooled in the oil cooler, thus causing
blockage and high oil pressures. Mask oil
cooler by suitable means to raise oil temper-
ature.
Check thermostat block, repair or replace if
necessary.
Check temperature sensor and indicator
and replace as necessary.
Check oil level and refill oil as necessary.
Note:
If the engine was accidently operated without
engine oil after performing an oil change –
expect severe engine damage. A teardown
inspection and repair ist strongly recom-
mended for safe operation.
Repair or replace oil pump.
Replace regulating piston or spring.
Clean ventilation, replace and properly in-
stall breather line (no bucklings or contrac-
tions).
