5. REMOVE CYLINDER HEAD COVER SUB-ASSY
a. Remove the 9 bolts and 2 nuts, and then remove the cylinder head cover.
6. REMOVE ENGINE UNDER COVER RH
7. INSPECT VALVE CLEARANCE
HINT: Inspect and adjust the valve clearance when the engine is cold.
a. Set the No. 1 cylinder to the TDC/compression.
1. Turn the crankshaft damper, and align its timing notch with the timing mark "0" of the chain cover.
2. Check that both timing marks on the camshaft timing sprocket and the camshaft timing gear 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. 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.
c. Turn the crankshaft 1 complete revolution (360°) and align its timing notch with the timing mark "0" of the chain cover.
