c. Apply a continuous bead of liquid gasket with tube presser
(commercial service tool) to intake valve timing control covers as
shown in the figure.
Use Genuine RTV Silicone Seal ant or equivalent. Refer to
GI-44, "
Recommended Chemical Product and Sealant".
d. Tighten mounting bolts in numerical order as shown in the fig- ure.
12. Install intake valve timing control position sensor, intake valve timing control solenoid valve and camshaft position sensor (PHASE) to intake valve timing control cover and front cover if removed.
 Be sure to tighten mounting bolts with flanges completely seated.
13. Install oil pan and oil strainer. Refer to EM-183, "
Component".
14. Install crankshaft pulley as follows:
a. Fix crankshaft with ring gear stopper [SST: J-45476].
b. Install crankshaft pulley, taking care not to damage front oil seal.  Install according to dowel pin of oil pump drive spacer.
 Lightly tapping its center with plastic hammer, insert pulley.CAUTION:
Do not tap pulley on the side surface where belt is installed (outer circumference).
c. Apply engine oil onto threaded parts of crankshaft pulley bolt and seating area.
d. Tighten crankshaft pulley bolt.
e. Put a paint mark on crankshaft pulley aligning with angle mark on crankshaft pulley bolt.
f. Further tighten by 90 degrees. (Angle tightening)  Check the tightening angle by referencing to the notches. Theangle between two notches is 90 degrees.
15. Rotate crankshaft pulley in normal direction (clockwise when viewed from engine front) to confirm it turns smoothly.
16. Install in the reverse order of removal after this step. NOTE:

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.

CAMSHAFT
 Install camshaft so that dowel pin on front end face are posi-
tioned as shown in the figure. (No. 1 cylinder TDC on its com-
pression stroke)
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.
3. Install camshaft brackets.  Remove foreign material completely from camshaft bracketbackside and from cylinder head installation face.
 Install by referring to installation location mark on upper sur-
face and front mark.
 Install so that installation location mark can be correctly read when viewed from the side of left exhaust bank.
 Apply liquid gasket to mating surface of camshaft bracket (No. 1) as shown in the figure.
Use Genuine RTV Silicone Seal ant or equivalent. Refer to
GI-44, "
Recommended Chemical Product and Sealant".
CAUTION:
 After installation, be sure to wipe off any excessive liq- uid gasket leaking from part “A” and “B” (both on right
and left sides).
 Remove completely any excess of liquid gasket inside bracket.
 Apply liquid gasket to mating surface of camshaft bracket (No. 6) on left bank intake as shown in the figure.
Use Genuine RTV Silicone Seal ant or equivalent. Refer to
GI-44, "
Recommended Chemical Product and Sealant".
CAUTION:
 After installation, be sure to wipe off any excessive liq- uid gasket leaking from part “A” and “B” (both on right
and left sides).
 Remove completely any excess of liquid gasket inside bracket.
