7. While putting your hands over the oil passage hole located

at the back of the engine oil control valve installation hole in
order to prevent air leakage, use an air blow gun to blow
compressed air to the oil pipe installation hole at the right
bank side. At that time, check that the rocker arm piston at
the right bank side is operated.

NOTE: To surely perform the check, wrap the top of the air
blow gun with a vinyl tape. Prevent compressed air leakage as
much as possible. The pressure of 620 kPa (90 psi) or more is
necessary for the compressed air.
8. Use the air blow gun to blow the compressed air to the oil

pipe installation hole at the left bank side. At that time, check
that the rocker arm piston at the left bank side is operated.

NOTE: To surely perform the check, wrap the top of the air
blow gun with a vinyl tape. Prevent compressed air leakage as
much as possible. The pressure of 620 kPa (90 psi) or more is
necessary for the compressed air.
9. Turn the crankshaft clockwise until the notch on the

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

10.Confirm the rest of the rocker arm pistons under the

procedure 7 - 8.

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

rocker arm assy.

12.Install the oil pipe and the engine oil control valve. (Refer to

Camshaft and Valve Stem Seal

13.Install the rocker cover.
14.Install all of the ignition coils.

IGNITION TIMING CHECK

M1111001702551

Required Special Tool:
MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: V.C.I.

• MB991827: M.U.T.-III USB Cable

• MB991910: M.U.T.-III Main Harness A

1. 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.

CAUTION

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting 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 11".
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,

refer to GROUP 13B, Multiport Fuel Injection (MFI) <3.0L
Engine>

CAUTION

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. Cancel the setting mode of the scan tool MB991958.
10.Check that the actual ignition timing is at the standard value.

Standard value: Approximately 10

° BTDC

NOTE: The ignition timing fluctuates about

, even under

normal operating condition.
NOTE: It is automatically further advanced by about 5

from

Before Top Dead Center at higher altitudes.

NOTE: Wait till approximately 1 minute passes after the
engine started, and check the ignition timing when the
engine stabilized.

11.Remove the timing light.
