(4) If oil pressure is 0 at idle. Shut off engine,
check for pressure relief valve stuck open, a clogged
oil pick-up screen or a damaged oil pick-up tube
O-ring.

STANDARD PROCEDURE
ENGINE OIL LEVEL CHECK
The best time to check engine oil level is after the
vehicle has sat overnight, or if the engine has been
running, allow the engine to be shut off for at least 5
minutes before checking oil level.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil level
reading. Remove dipstick (Fig. 107) or (Fig. 108), and
observe oil level. Add oil only when the level is at or
below the MIN mark (Fig. 109).
CAUTION: Do not operate engine if the oil level is
above the MAX mark on the dipstick. Excessive oil
volume can cause oil aeration which can lead to
engine failure due to loss of oil pressure or
increase in oil temperature.
