OIL PRESSURE CHECK
Check periodically the oil pressure in the engine to judge roughly the condition of the moving parts.
OIL PRESSURE SPECIFICATION
If the oil pressure is lower or higher than the specification, the following causes may be considered.
LOW OIL PRESSURE
* Clogged oil filter
* Oil leakage from the oil passage way
* Damaged O-ring
* Defective oil pump
* Combination of the above items
HIGH OIL PRESSURE
* Used of high viscosity engine oil
* Clogged oil passage way
* Combination of the above items
OIL PRESSURE TEST PROCEDURE
Start the engine and check if the oil pressure indicator light is
turned on. If it keeps on lighting, check the oil pressure indicator
light circuit. If it is in good condition, check the oil pressure in the
following manner.
• Remove the main oil gallery plug 1.
• Install the oil pressure gauge with attachment in the position
shown in the photo.
• Warm up the engine as follows:
Summer 10 min at 2 000 r/min
Winter 20 min at 2 000 r/min
• After warming up, increase the engine speed to 3 000 r/min
(with the multi circuit tester 2-13), and read the oil pres-
sure gauge.
