7.

Measure the valve clearance for intake side.
If the valve clearance is not as specified, loosen the rocker
arm lock nut and adjust the clearance using a thickness gauge
while turning the adjusting screw.

Standard value (hot engine): 0.20 mm (0.008 inch)

NOTE:

Valve clearance check and adjustment is

unnecessary for exhaust side due to auto lash adjuster
installed.

8.

While holding the adjusting screw with a screwdriver to
prevent it from turning, tighten the lock nut to the specified
torque.

Tightening torque: 9 ± 1 N·m (80 ± 9 in-lb)

9.

Turn the crankshaft 360 degrees to line up the notch on the
crankshaft pulley with the "T" mark on the timing indicator.

10.

Repeat steps (7) and (8) on other valves for clearance
adjustment.

11.

Install the rocker cover.

12.

Install the ignition coils.

Move the rocker arms on the No.1 and No.4 cylinders up and
down by hand to determine which cylinder has its piston at the
top dead center on the compression stroke.

NOTE:

The rocker arm piston operation check can be

performed on rocker arms indicated by white arrow mark
when the No.1 cylinder piston is at the top dead center
on the compression stroke, and on rocker arms indicated
by black arrow mark when the No.4 cylinder piston is at
the top dead center on the compression stroke.

7.

While shutting up the oil passage hole at the depth of the
engine oil control valve's installation hole by finger not to leak
air, blow compressed air into the engine oil pressure switch's
installation hole by air blowgun. At this time, confirm that the
rocker arm piston can operate.

NOTE:

To fully confirm the check, prevent the compression

air from leaking as much as possible by bind vinly tape
to the end of air blowgun. The compression air pressure
is required more than 620 kPa (90 psi).

8.

Turn the crankshaft clockwise until the notch on the crankshaft
pulley is lined up with the "T" mark on the lower cover of timing
belt.

9.

Confirm the rest of the rocker arm pistons under the procedure
7.

10.

When the rocker arm piston does not operate, replace the
rocker arm assy.

11.

Install the engine oil pressure switch and the engine oil
control valve. (Refer to Camshaft and Valve Stem Seal -
Removal and Installation P.11A-27.)

12.

Install the rocker cover.

13.

Install all of the ignition coils.

Before inspection, set the vehicle in the following condition:

｠

Engine coolant temperature: 80 - 95°C (176 - 203°F)

｠

Lights and all accessories: OFF

｠

Transaxle: P range

NOTE:

On vehicles for Canada, the headlight, taillight,

etc. remain lit even when the lighting switch is in "OFF"
position but this is no problem for checks.

To prevent damage to scan tool MB991958, always turn
the ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991958.

2.

Connect scan tool MB991958 to the data link connector.

3.

Set the timing light to the power supply line (terminal No. 1) of
the ignition coil No. 2.

NOTE:

The power supply line is looped and also longer

than the other ones.

4.

Start the engine and run it at idle.

5.

Check that the idle speed is approximately 600 r/min.

6.

Select scan tool MB991958 actuator test "item number 4".

7.

Check that basic ignition timing is within the standard value.

Standard value: 5° BTDC ± 3°

8.

If the basic ignition timing is not within the standard value,
check the following items:

｠

Diagnostic output

｠

Timing belt cover and crankshaft position sensor installation
conditions

｠

Crankshaft sensing blade condition

If the actuator test is not canceled, the forced drive will
continue for 27 minutes. Driving in this state could lead
to engine failure.

9.

Press the clear key on scan tool MB991958 (select forced
drive stop mode), and cancel the actuator test.

10.

Check that the actual ignition timing is at the standard value.

Standard value: Approximately 10° BTDC

NOTE:

Ignition timing fluctuates about ± 7° Before Top

Dead Center, even under normal operating condition.

NOTE:

It is automatically further advanced by about 5°

to 10° Before Top Dead Center at higher altitudes.
