d. Check the valves indicated in the illustration.
1. Using a feeler gauge, measure the clearance between the valve lifter and camshaft.
Valve clearance (Cold):
Intake 0.15 - 0.25 mm (0.006 - 0.010 in.)
Exhaust 0.25 - 0.35 mm (0.010 - 0.014 in.)
2. Record the out-of-specification valve clearance measurements. They will be used later to determine the required replacement adjusting
shim.
8. ADJUST VALVE CLEARANCE
NOTICE: When rotating the camshaft with the timing chain removed, rotate the crankshaft damper counterclockwise 40° from the TDC and
align its timing notch with the matchmark of the timing chain cover to prevent contact of the pistons with the valves.
a. Set the No. 1 cylinder to the TDC/compression.
1. Turn the crankshaft damper, and align its timing notch with timing mark "0" of the chain cover.
2. Check that both timing marks on the camshaft timing sprocket and valve timing controller assembly are facing upward as shown in the
illustration.
HINT: If not, turn the crankshaft 1 complete revolution (360°) and align the marks as above.
b. Put paint marks on the timing chain in place where the timing marks of the camshaft timing sprocket and the camshaft timing gear are located.
