5. Inspect the valve clearance.
1) Check only the valve indicated as shown. [No. 1 cylinder: TDC/compression]. Measure the valve clearance.
1) Using a thickness gauge, measure the clearance between the tappet shim and the base circle of camshaft.
2) Record the out-of-specification valve clearance measurements. They will be used later to determine the required replacement adjusting
shim.
Valve clearance [Specification]
Engine coolant temperature: (20°C ± 5°C [68°F ± 9°F])
Intake: 0.20 mm (0.0079 inch)
Exhaust: 0.28 mm (0.0110 inch)
[Limit]
Intake: 0.12 - 0.28 mm (0.0047 - 0.0110 inch)
Exhaust: 0.20 - 0.38 mm (0.0079 - 0.0150 inch)
[Reference data] Engine coolant temperature: 80°C [176°F]
Intake: 0.29 mm (0.0114 inch)
Exhaust: 0.34 mm (0.0134 inch)
2) Turn the crankshaft pulley one revolution (360°) and align the groove with the timing mark T of lower timing belt cover.
3) Check only valves indicated as shown. [No. 4 cylinder: TDC/compression]. Measure the valve clearance. (See procedure step (1))
6. Adjust the intake and exhaust valve clearance.
1) Turn the crankshaft so that the cam lobe of the camshaft on the adjusting valve is upward.
2) Using the SST (09220-2D000), press down the valve lifter and place the stopper between the camshaft and valve lifter and remove the special
tool.
