(3) If any abnormal noise IS not eliminated by racing, check the
lash adjuster.
@ Stop the engine.
@ Set the engine so that cylinder No. 1 is positioned at
the top dead centre of the compression.
@ Press the rocker arm at the area indicated by the+ arrow mark to check whether the rocker arm is lowered
or not.
@ Slowly turn the crankshaft 360 degrees clockwise.
@ In the same procedure as Step 0, check the rocker
arm at the area indicated by the
0 arrow mark.
@ If the rocker arm lowers easily when the part directly
above the rocker arm lash adjuster is pressed, the lash
adjuster is defective and must be replaced. When re-
placing the lash adjuster, bleed the air from all adjus-
ters and then assemble them. Then inspect with proce-
dures
@ to 0, and confirm that there are no abnormal-
ities
NOTE
lThe lash adjuster can be accurately checked for de-
fects with the leak down test.
l Refer to the engine service manual for the leak down test and lash adjuster air bleeding procedure.
If the rocker arm is extremely hard when pressed
down, the lash adjuster is normal, so look for a different
cause of abnormal sound.
COMPRESSION PRESSURE CHECK
MllFFAL
(1) Before inspection, verify that the engine oil, starter motor and battery are normal. Then, perform the following.
l Engine coolant temperature:
80- 95°C
(176- 203°F)
l Lights, electric cooling fan and accessories: OFF
l Transaxle:
P range
0 Steering wheel: Neutral position
(2) Disconnect the spark plug cable.
(3) Remove all the spark plugs
(4) Disconnect the connector of the distributor.
NOTE
This will prevent the engine control module from controll- ing the ignition and fuel injection.

(5) Cover the spark plug holes with a cloth, etc., and crank the engine. Then verify that no foreign material sticks to the
cloth, etc.
Caution
1. During cranking, be especially careful of the spark plug
installing hole.
2.Very hot water, oil, fuel, etc., which may have entered
the cylinder somehow, will violently spout through the spark plug hole if the compression is measured in the
entrapped state. This is very dangerous.

Set up the compression gauge in the spark plug mounting
hole.
Fully open the throttle valve, and cranking the engine,
measure the compression pressure.
Standard value:
<8VALVE>1,250 kPa (178 psi) [250-400 rpm]
< 1 Ei VALVE>
1,300 kPa (185 psi) [250-400 rpm]
Limit:
(8 VALVE>880 kPa (125 psi) [250-400 rpm]
980 kPa (139 psi)
[250-400 rpm]
Measure the compression pressure of each cylinder, and
verify that the pressure difference among the cylinders is
less than the limit value.
Limit: max. 100
kPa (14 psi)
(9) If a cylinder’s compression pressure or pressure difference IS outside
the limit, fill a small amount of engine oil through
the spark plug hole and repeat Items (7) and (8) above.
@ If the compression is increased when the oil is filled, the piston and/or cylinder wall may be worn or
damaged.
@ If the compression is not increased even though the oil is filled, the valve may be thermally seized, the valve
contact may be improper or pressure may leak at the
gasket.
(10) Connect the connector of the distributor.
(11) Install the spark plug and spark plug cable.
(12)Erase the diagnostic trouble code with the Scan tool or re-
connect the battery (-)

was disconnected.
NOTE
This will erase the memory of the diagnostic trouble code

(3) Remove the PCV hose from the PCV valve and attach a
vacuum gauge.
(4) Check that the negative pressure at the intake manifold
during idle revolution is normal.

There are 2 access holes in the timing belt front lower cover.
These can be used to readjust the tension of the timing belt by
the following procedure without removing the timing belt front lower cover. However, timing belt “B”, which drives the right
silent shaft, cannot be adjusted unless the cover is removed. (1) Turn the steering wheel all the way to the left.
(2) Remove the left side undercover panel.
NOTE
This work is done so that the crankshaft can be turned.

DASH POT INSPECTION AND ADJUSTMENT

(1) Perform after inspecting the idle rotation speed.
(2) The vehicle should be prepared as follows before the inspection.

80- 95°C
(176- 203°F)
lLights, electric cooling fan and accessories: OFF
l Transaxle: Neutral
l Steering wheel: neutral position
(3) Either set the tachometer or connect the data link connec- tor (white) to the scan tool.
NOTE
For setting the tachometer. refer to GROUP 13 - Service
Adjustment Procedures.
(4) Start the
engine.
(5) Open the throttle valve until the dash pot rod is fully
stroked.
(6) Gradually close the throttle valve until you find the point where the throttle lever touches the dash pot rod (the dashpot begins to shorten).
Maintain the throttle valve at this touching point,
(7) Check the engine speed (speed when the dash pot begins to operate).
Standard value: 3,900
f 200 rpm
(8) If outside the standard value, loosen the rod’s lock nut and turn the rod to adjust.
(9) To release the maintained state of the throttle valve, check that the engine speed gradually decreases to the idle speed, (10)Disconnect
the closed throttle position switch connector
(fixed SAS).

BASIC IDLE SPEED ADJUSTMENTMlIFHBX
NOTE
1. The standard idling speed has been adjusted, by the en-
gine speed adjusting screw, by the manufacturer, and
there should usually be no need for readjustment.
2. Use the following procedure to adjust when the idling speed drops due to an incorrect adjustment, high idling
speed, or when a load such as the air conditioning is ap-
plied on the engine.
3. The adjustment, if made, should be made after first con- firming that the spark plugs, the injectors, the idle air con-
trol motor, the compression pressure, etc. are all normal.
(I ) The vehicle should be prepared as follows before the inspec- tion and adjustment.
l Engine coolant temperature:
85-95°C (185-203°F)
l Lights, cooling fan and accessories: OFF
l Transaxle: neutral (A/T for
P range)
l Steering wheel: neutral position
(2) Connect the scan tool to the data link connector (white).
NOTE
When the scan tool is connected, the diagnostic test mode control terminal should be grounded.
(3) If the scan tool is not used, follow the steps below.
