(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 (-)
cable
10 seconds or more after it
was disconnected.
NOTE
This will erase the memory of the diagnostic trouble code
which
resu,lted from disconnection of the distributor con-
nector.
(1) Before inspection and adjustment, put the vehicle into the
followin~g state.
l Engine coolant temperature:
85-95°C (185-203°F)
l
Ligt-Its, electric, cooling fan, and accessories: OFF
l Transaxle: Neutral
(N or P for vehicles with an automa-
tic transaxle)
l Steering wheel: Neutral position
(2) Check that the idling revolution speed is normal.
