4. Crank the engine, and then make sure that engine oil comes out
from intake valve timing control cover oil hole. End crank after
checking.
WARNING:
Be careful not to touch rotating parts (drive belt, idler pul-
ley, and crankshaft pulley, etc.).
CAUTION:
Engine oil may squirt from intake valve timing control sole-
noid valve installation hole during cranking. Use a shop
cloth to prevent the engine components and the vehicle. Do
not allow engine oil to get on rubber components such as
drive belt or engine mount insulators. Immediately wipe off
any splashed engine oil.

Clean oil groove between oil strainer and intake valve timing control solenoid valve if engine oil does not
come out from intake valve timing control cover oil hole. Refer to LU-23, "
LUBRICATION SYSTEM" .
5. Remove components between intake valve timing control solenoid valve and camshaft sprocket (INT), and then check each oil groove for clogging.

Clean oil groove if necessary. Refer to LU-23, "LUBRICATION SYSTEM" .
6. After inspection, install removed parts.
Valve ClearanceNBS003IF
INSPECTION
In cases of removing/installing or replacing camshaft and valve-related parts, or of unusual engine conditions
due to changes in valve clearance (found malfunctions during starting, idling or causing noise), perform
inspection as follows:
1. Remove rocker covers (right and left bank). Refer to EM-200, "
ROCKER COVER" .
2. Measure the valve clearance as follows:
a. Set No. 1 cylinder at TDC of its compression stroke.

Rotate crankshaft pulley in clockwise to align TDC identifica-
tion notch (without paint mark) with timing indicator on front
cover.

Make sure that both intake and exhaust cam noses of No. 1
cylinder (engine front side of left bank) are located as shown
in the figure.

If not, turn crankshaft one revolution (360 degrees) and align
as shown in the figure.

3. Using small screwdriver, turn the round hole of adjusting shim in
the direction of the arrow.
CAUTION:
perform (the above procedure) during camshaft do not con-
tact with adjusting shim.
4. Install lifter stopper [SST: 10115120 (J38972-2)] as follows:
a. Except exhaust side of No. 7 and 8 cylinder;
i. Place camshaft pliers (SST) around camshaft as shown in the figure.
ii. Rotate camshaft pliers so that valve lifter is pushed down. CAUTION:
Be careful not to damage cam surface, valve lifter and cylin-
der head with camshaft pliers.
iii. Place lifter stopper between camshaft and the edge of valve lifter to retain valve lifter.
CAUTION:

Lifter stopper must be placed as close to camshaft
bracket as possible.

Be careful not to damage cam surface, valve lifter and
cylinder head with lifter stopper.
iv. Remove camshaft pliers. CAUTION:
Camshaft pliers should be removed by rotating it slowly
because lifter stopper hits and damages journal portion by
rotating camshaft pliers quickly.
b. Exhaust side of No. 7 and 8 cylinder;
NOTE:
Exhaust side of No. 7 and 8 cylinder does not have space for installing camshaft pliers [SST: KV10115110
(J38972-1)]. therefore, install lifter stopper [SST: KV10115120 (J38972-2)] according to the following
instructions.
i. Rotate crankshaft to press cam nose to the adjusting part of valve lifter.
ii. Place lifter stopper between camshaft and the edge of valve lifter to retain valve lifter.
CAUTION:

Lifter stopper must be placed as close to camshaft bracket as possible.

Be careful not to damage cam surface, valve lifter and cylinder head with lifter stopper.
iii. Rotate crankshaft slowly 180 degrees clockwise. CAUTION:
Rotating crankshaft slowly because lifter stopper hits and damages journal portion by rotating
crankshaft quickly.
