(3) lf
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.
@ ln the same procedure as Step 0, check the rocker
arm at the area indicated by the
4 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
@I 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.
DASH POT INSPECTION AND ADJUSTMENT

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

(11)Check that there is continuity between the closed throttle
position switch terminal and body.
NOTE
When there is continuity, a clearance will be created between the throttle lever and dash pot rod when the dash
pot rod is pressed lightly.
(12) When there is no continuity, lower the engine speed when the dash pot begins operation to within the standard value
tolerance. Make sure to create continuity between the
closed throttle position switch terminal and body.
COMPRESSION PRESSURE CHECK Ml 1 FFAL
(1) Before inspection, verify that the engine oil, starter motor
and battery are normal. Then, perform the following.
lEngine coolant temperature: 80- 95°C
(1 76- 205’F)
l Lights, electnc
cooling fan and accessories: OFF
0 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 crankshaft position sensor.
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
vex/ dangerous.
(6) Set up the compression gauge in the spark plug mounting
hole.
(7) Fully open the throttle valve, and cranking the engine.
measure the compression pressure.
Standard value: Up to 1991: 1,350
kPa (192 psi) [250- 400 rpml
From 1992: 1,550
kPa (220 psi) [250-400 rpm]
1 ,150 kPa (164 psi) [250- 400 rpml
Limit:

up to 1991: 960

From 1992: 1 ,120 kPa (159 psi) [250- 400 rpml
CTurbo>
800
kPa (114 psi) [250- 400 rpml
(8) Measure the compression pressure of each cylinder. and verify that the pressure difference among the cylinders
is
less than the limit value.
