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),

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.
