1. Make sure that crankshaft key and dowel pin of each camshaft
are located as shown in the figure. (No. 1 cylinder at compres-
sion TDC)
NOTE:
Though camshaft does not stop at the position as shown in the
figure, for the placement of cam nose, it is generally accepted
camshaft is placed for the same direction of the figure.
2. Install camshaft sprockets.  Install onto correct side by checking with identification mark onsurface.
 Install camshaft sprocket (EXH) by selectively using the
groove of dowel pin according to the bank. (Common part
used for both banks.)
 Lock the hexagonal part of camshaft in the same procedure as for removal, and tighten mounting bolts.
3. Install crankshaft sprockets for both banks.  Install each crankshaft sprocket so that its flange side (thelarger diameter side without teeth) faces in the direction shown
in the figure.
NOTE:
The same parts are used but facing directions are different. Camshaft dowel pin
: At cylinder head upper face side in each bank
Crankshaft key : At cylinder head side of left bank

3. With hexagonal part of camshaft locked with wrench, loosen
bolts securing camshaft sprocket to remove camshaft sprocket.
CAUTION:
 Do not loosen mounting bol ts with securing anything
other than the camshaft hexagonal portion or with ten-
sioning the timing chain.
 After removing timing chain, do not turn crankshaft and
camshaft separately, or valves will strike the piston head.
4. Remove intake and exhaust camshaft brackets.  Mark camshafts, camshaft brackets and bolts so placed in the same position and direction for installa-
tion.
 Equally loosen camshaft brackets and bolts in several steps in reverse order as shown in the figure.
 Lightly tapping with plastic hammer, remove camshaft bracket (No. 1) and camshaft bracket (No. 6).
NOTE:
The bottom surface of each bracket will be stuck to cylinder
head because of liquid gasket.
5. Remove camshaft.
6. Remove valve lifter if necessary.  Identify installation positions, and store them without mixing them up.
INSPECTION AFTER REMOVAL
Camshaft Runout
1. Put V-block on precise flat table, and support No. 2 and 5 journalof camshaft.
CAUTION:
Do not support journal No. 1 (on the side of camshaft
sprocket) because it has a differe nt diameter from the other
four locations.
2. Set dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the camshaft runout on dial indicator. (Total indicator reading)
4. If it exceeds the limit, replace camshaft.

CAMSHAFT
 Install dial indicator in thrust direction on front end of camshaft.
Measure the end play of dial indicator when camshaft is moved for-
ward/backward (in direction to axis).
 Measure the following parts if out of the limit.
- Dimension “A” for camshaft No. 1 journal
- Dimension “B” for cylinder head No. 1 journal bearing
 Refer to the standards above, and then replace camshaft and/or cylinder head.
Camshaft Sprocket Runout
1. Put V-block on precise flat table, and support No. 2 and 5 journal of camshaft.
CAUTION:
Do not support journal No. 1 (on the side of cam shaft sprocket) because it has a different diameter
from the other four locations.
2. Measure the camshaft sprocket runout with dial indicator. (Total indicator reading)
 If it exceeds the limit, replace camshaft sprocket.
Valve Lifter
Check if surface of valve lifter has any wear or cracks.
 If anything above is found, replace valve lifter. Refer to EM-218,

INSPECTION AFTER INSTALLATION
Inspection of Camshaft Sprocket (INT) Oil Groove
CAUTION:
 Perform this inspection only when DTC P0011 and/ or P0021 are detected in self-diagnostic results of
CONSULT-III and it is directed according to inspection procedure of EC section. Refer to EC-666,
"Trouble Diagnosis Introduction".
 Check when the engine is cold so as to prevent burns from any splashing engine oil.
1. Check the engine oil level. Refer to LU-23, "
Inspection".
2. Perform the following procedure so as to prev ent the engine from being unintentionally started while
checking. : 1.96 N·m (0.2 kg-m, 1 ft-lb)

a. Release fuel pressure. Refer to
EC-665, "Fuel Pressure Check".
b. Disconnect ignition coil and injector harness connectors.
3. Remove intake valve timing control solenoid valve. Refer to EM-199, "
Component".
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 rotati ng 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 co mponents 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-21, "
Lubrication Circuit".
5. Remove components between intake valve timing c ontrol solenoid valve and camshaft sprocket (INT),
and then check each oil groove for clogging.
 Clean oil groove if necessary. Refer to LU-21, "
Lubrication Circuit".
6. After inspection, install removed parts.
Valve ClearanceINFOID:0000000001325792
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 dur ing starting, idling or causing noise), perform
inspection as follows:
1. Remove rocker covers (right and left bank). Refer to EM-196, "
Component".
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.
