Oil Pressure
Testing
lf the oil pressure warning light stays on with the enginerunning, check the engine oil level. lf the oil level is
correct:
1. Connect a tachometer.
2. Remove the oil pressure switch and install an oil pres-
sure gauge.
3. Stan the engine. Shut it off immediately if the gauge
registers no oil pressure. Repair the problem before
continuing.
4. Allow the engine to reach operating temperatu,e {fancomes on at least twice). The Dressure should be:
Engine Oil Pressure:
At ldle: 70 kPa (0.7 kgf/cmr, 10 psi)
minimum
At 3,OOO lpm: 340 kPa {3.5 kgf/cmz, 50 psi}
minimum
a lJ oil pressure is within speciJications, replace the
engine oil pressure switch and recheck.
a lf oil pressure is NOT within specifications, in-
spect the oil pump (see page 8-1O).

Oil Jet
Inspection (B18C1 engine only|
Remove the oil jet (see page 8-4) and inspect it as
follows.
a Make sure that a I .l mm (O.04 in) diameter drill
will go through the nozzle hole {1 .2 mm {O.OS in)
diameterl.
a Insert the other end of the same 1.1 mm (O.O4
in) drill into the oil intake {1.2 rnm {0.05 in}
diameter).
Make sure the check ball moves smoothlv and has
a stroke of approximately 4.0 mm {O. 16 in).a Check the oil jet operation with an air nozzle. lt
should take at least 2OO kPa (2.O kgf/cmr,28
Dsi) 10 unseat the check ball.
NOTE: Replace the oiljet assembly if the nozzle
is damaged or bent.
2. Mounting torque is critical. Be very precise when in-
stalling.
