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:

CAMSHAFT
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.
