Valve Clearance: Adjustments

ADJUSTMENT

CAUTION:
If engine oil is spilt onto the exhaust pipe, wipe it off with cloth to avoid emission of smoke or causing a fire.

NOTE:
Adjustment of valve clearance should be performed while engine is cold.

1) Measure all the valve clearances.

NOTE:
Record each valve clearance after measurement.





2) Remove the camshaft.
3) Remove the valve lifter.
4) Measure the thickness of valve lifter using micrometer.





5) Select and install a valve lifter of suitable thickness from the following table, based on the measured valve clearance and valve lifter thickness.

NOTE:
Use a new valve lifter.











6) Install the camshaft.
7) Install the cam sprocket.
8) Install the timing belt.
9) Measure all valves for valve clearance again at this time. If the valve clearance is not within the adjustment value, repeat the procedure over again from the first step.
Valve clearance (adjustment value):
Intake
0.20 +0.01/-0.03 mm (0.0079 +0.0004/-0.0012 in)
Exhaust
0.35 ± 0.02 mm (0.0138 ± 0.0008 in)

10) After measuring, install the related parts in the reverse order of removal.

NOTE:
^ Use a new rocker cover gasket.
^ Use a new clamp for the PCV hose clamp, fit the cut out in the ST with the protrusion on the clamp as shown in the figure, and lock the clamp.
