DIAGNOSTIC INFORMATION AND PROCEDURE
COMPRESSION PRESSURE CHECK
Tools Required
09915–64510 Compression Pressure Gauge
Check the compression pressure in the following proce-
dures:
1. Warm up the engine to the normal operating tempera-
ture (Cooling temperature : 80–90
_
C (176–194
_
F)).
2. Stop the engine and then remove the high tension
cable and the spark plug.
3. Disconnect the distributor optical sensor connector.
4. Install the compression pressure gauge 09915–64510
(a) in the hole of spark plug.
D12B301A
5. Disengage the clutch in Neutral (to lighten starting
load on engine upon cranking), and depress the ac-
celerator all the way to make the throttle fully open.
6. Crank the engine with the starting motor, and read the
highest pressure on the compression pressure gauge.
D
The difference of measured value between cylinders
is 98.06kPa (14.22 psi) and less.
D
On checking, make the connection perfectly airtight
between the hole of spark plug and compression pres-
sure gauge.

7. After checking, remove the gauge and install the re-
moved parts.
OIL PRESSURE CHECK
Tools Required
09915–77310 Oil Pressure Gauge
Prior to check oil pressure, check the followings:
D
Check oil level and add if required.
D
Replace the discolored, deteriorated or diluted oil.
D
Check any oil leakage and repair the defective parts.
Check the compression pressure in the following proce-
dures:
1. Remove the oil pressure switch (b) from the cylinder
block.
2. Install the oil pressure gauge 09915–77310 (c) to the
mounting place of the oil pressure switch.
D12B302A
3. Start the engine and warm up to the normal operating
temperature.
4. Raise the engine speed up to 2,000rpm and then
read oil pressure.

ADJUSTMENT OF VALVE
CLEARANCE
Adjust the valve clearance in the following procedures:
1. Remove the air filter/resonator assembly and the
relevant parts installed on the cylinder head cover.
2. Remove the cylinder head cover hexagon bolts and
remove the cover.
3. Turn over the crankshaft to make No.1 cylinder
matched with the compression top dead center.
(When the camshaft sprocket notch (d) is aligned with
the timing belt rear cover triangle pointer (e) and the
crankshaft sprocket point (f) is aligned with the oil
pump housing point (g), the compression top dead
center is on the ignition sequence for No. 1 cylinder.)

4. Check the valve clearance for No. 1 cylinder com-
pression top dead center.

5. If the checking for the valve clearance of No.1 cylin-
der compression top dead center is over, position
No.1 cylinder on the exhaust top dead center as rotat-
ing the crankshaft in a 360–degree arc. (When the
camshaft sprocket point (h) is aligned with the timing
belt rear cover triangle pointer (e), the exhaust top
dead center is on the ignition sequence for No. 1 cyl-
inder.)
