Oil Pressure
Testing
lf the oil pressure warning light stays on with the enginerunning, check the engine oil level. It the oil level iscorrect:
Connect a tachometer.
Remove the oil pressure switch and install an oil pressure gauge.
Start the engine. Shut it off immediately if the gaugeregasters no oil pressure. Repair the problem beforecontinuing.
Allow the engine to reach operating temperature (fan
comes on at least twicel. The pressure should be:
Engine Oil Pressure:
At ldle: 70 kPa {O.7 kgficmr, tO psil
minimum
At 3,OOO rpm: 34O kPa (3.5 kgf/cmr, 50 psil
minimum
a lf oilpressure is within specifications, replace theengine oil pressure switch and recheck.
a lf oil pressure is NOT within specifications,rnspect the oil pump (see page g-11).

1. Remove the oil jet (see pages 8 4 or 8 5) and inspectit as follows.
a Make sure rhat a 1 .1 mm (O.04 in) diameter drillwillgo through the nozzle hole fl.2 mm (O.O5 in)diameter).
a Insert the other end of the same 1 .1 mm {0.O4in) drill into the oit intake (1.2 mm (0.05 in)diameter).
Make sure the check ball moves smoothly and hasa stroke of approximately 4.0 mm (O.16 in).a Check the oil jet operation with an air nozzle. ltshould take at least 2OO kPa 12.O kg|lcm2, 2gpsi) to unseat the check ball.
NOTE: Replace the oiljet assembly if the nozzleis damaged or bent.
2. Mounting torque is critical. Be very precise when in-stalling.

Apply a light coat of oil to the seal lip.
Install the two dowel pins and new O-ring on the oil
pump.
Apply liquid gasket to the cylinder block mating sur-
face ol the oil pump.
NOTE:
. Use liquid gasket, Part No, 08718 - 0001 or 08718

elapsed since applying liquid gasket. Instead,
reapply liquid gasket atter removing the old
