Oil-pressure check
Check the oil pressure regularly. This should
provide useful information on the condition of the
engine moving parts.
DETAILS:
Oil pressure:
Up 40 Kpa (0.4 Kgf/cm, 5.7 psi) at 3000 rpm
Up 140 Kpa (1.4 Kgf/cm, 19.9 psi)
Oil-pressure check procedure
Attach a tachometer to the high-voltage cable.
Remove the plug from the main oil circuit.
Warm up the engine as follows:
Summer: 10 minutes at 2000 rpm.
Winter: 20 minutes at 2000 rpm.
After warming up the engine, incrase the turning
speed to 3000 rpm (check the tachometer) and
record the oil-pressure readout from the
tachometer.
Tool Description:
Pressure gauge.
Adaptor.
Low or high pressure may indicate some
of the conditions below:
Low oil pressure:
- Clogged oil filter.
- Leaking in oil ducts.
- Damaged ring seal.
- Defective oil pump.
- A combination of the defects above.
High oil pressure:
- Oil viscosity too high.
- Blocked oil ducts.
