Valve Clearance: Adjustments

Adjustment

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

1. Measure all valve clearances.

NOTE: Record each valve clearance after it has been measured.





2. Remove the camshaft.
3. Remove the valve lifter.
4. Measure the thickness of valve lifter with a micrometer.





5. Select a shim of suitable thickness using measured valve clearance and valve lifter thickness, by referring to the following table.











6. Inspect all valves for clearance again at this stage. If the valve clearance is not correct, repeat the procedure over again from the first step.
7. After inspection, install the related parts in the reverse order of removal.
