(a) Disconnect the ventilation hose from the cylinder head
cover.
7. REMOVE CYLINDER HEAD COVER SUB±ASSY
(a) Remove the 9 bolts, 2 seal washers, 2 nuts, 3 clamp
brackets and cylinder head cover.
8. REMOVE ENGINE UNDER COVER SUB±ASSY NO.1
9. REMOVE ENGINE UNDER COVER RH
10. SET NO. 1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley, and align the timing notch with
timing mark º0º of the timing chain cover.
(b) Check that the point marks of the camshaft timing sprock-
et and VVT timing sprocket are in straight line on the tim-
ing chain cover surface as shown in the illustration.
HINT:
If not, turn the crankshaft 1 revolution (360) and align the
marks as above.
11. INSPECT VALVE CLEARANCE
(a) Check the valves indicated in the illustration.
(1) Using a feeler gauge, measure the clearance be-
tween the valve lifter and the camshaft.
(2) Record the out±of specification valve clearance
measurements. They will be used later to determine
the required replacement valve lifter.
Valve clearance (Cold):
Intake 0.15 to 0.25 mm (0.0059 to 0.0098 in.)
Exhaust 0.25 to 0.35 mm (0.0098 to 0.0138 in.)
