8. SET NO. 1 CYLINDER TO TDC/COMPRESSION
(a) Turn the crankshaft pulley, and align its groove with timing
mark ”0” 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.
9. INSPECT VALVE CLEARANCE
(a) Check only the valves indicated.
(1) Using a feeler gauge, measure the clearance be-
tween the valve lifter and 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 – 0.25 mm (0.0059 – 0.0098 in.)
Exhaust 0.25 – 0.35 mm (0.0098 – 0.0138 in.)
(b) Turn the crankshaft 1 revolution (360 ) and set No. 4 cyl-
inder to TDC/compression.
(c) Check only the valves indicated.
(1) Using a feeler gauge, measure the clearance be-
tween the valve lifter and 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 – 0.25 mm (0.0059 – 0.0098 in.)
Exhaust 0.25 – 0.35 mm (0.0098 – 0.0138 in.)
