Oil pressure check
- After removing the flywheel cover as described
in the "Flywheel" chapter, remove the electric con-
nexion of the minimum oil pressure switch and
then remove the switch.
- With the engine idling at 1750 rpm and the oil
temperature at ~90°C, check that the oil pressure
is between 0.5 to 1.2 atm.
- With the engine idling at 5000 rpm and the oil
temperature at ~90°C, check that the oil pressure
is between 3.2 to 4.2 atm.
- Remove the specific tools on the engine once the
measurement is complete. Refit the oil pressure
switch and washer, tightening it to the prescribed
torque, and fit the flywheel cover.
- If oil pressure reading are not within the specified
limits, check in the following order: the oil filter, the
oil by-pass valve, the oil pump and the crankshaft
seals.
