(e)Inspect cylinder compression pressure.
SST09992±00500
(1)Insert a compression gauge into the spark plughole.
(2)Fully open the throttle.
(3)While cranking the engine, measure the compres- sion pressure.
Compression pressure:
1,300 kPa (13.3 kgf/cm
2, 189 psi)
Minimum pressure:
1000 kPa (10.2 kgf/cm
2, 145 psi)
Difference between each cylinder:
100 kPa (1.0 kgf/cm
2, 14 psi)
NOTICE:

Always use a fully charged battery to obtain engine
speed of 250 rpm or more.

Check other cylinder's compression pressure in the
same way.

This measurement must be done in as short a time as
possible.
(4)If the cylinder compression is low, pour a small amount of engine oil into the cylinder through the
spark plug hole and inspect again.
HINT:

If adding oil increases the compression, the piston rings
and/or cylinder bore may be worn or damaged.

If pressure stays low, a valve may be sticking or seating
improperly, or there may be leakage past the gasket.
10.INSPECT CO/HC
(a)Start the engine.
(b)Run the engine at 2,500 rpm for approximately 180 seconds.
(c)Insert CO/HC meter testing probe at least 40 cm (1.3 ft) into the tail\
pipe during idling.
(d)Check CO/HC concentration at idle. Idle CO concentration: 0 to 0.5 %
Idle HC concentration: Applicable local regulation
(e)If the CO/HC concentration does not conform to specifications, perform troubleshooting in the order given below.
(1)Check heated oxygen sensor operation. (See page 12±6)
(2) See the table below for possible causes, and then inspect and repair the applicable causes ifnecessary.

(c) Put air pressure into the oil port with 150 kpa (1.5 kgf/cm2
21 psi), and turn the camshaft timing gear to the advance
direction (counterclockwise) by hand.
CAUTION:
Cover the paths with shop rag to avoid oil splashing.
HINT:
Depending on the air pressure, the camshaft timing gear will
turn to the advance angle side without applying force by hand.
Also, under the condition that the pressure can be hardly ap-
plied because of the air leakage from the port, there may be the
case that the lock pin could be hardly released.
(d) Remove the fringe bolt of camshaft timing gear.
NOTICE:

Be sure not to remove the other 4 bolts.

If reusing the camshaft timing gear, release the
straight pin lock first, and then install the gear.

(a) Put the camshaft timing gear and the camshaft together
with the straight pin off the key groove.
(b) Turn the camshaft timing gear assembly to the left direc-
tion (as shown in the illustration) while lightly pushing it to-
ward the camshaft. Push further at the position where the
pin gets into the groove.
NOTICE:
Be sure not to turn the camshaft timing gear to the retard
angle side (to the right direction).
