NOTE:

Adjustment of valve clearance should be performed while engine is cold.
Do not wear gloves during removal and installation of valve lifter.
Do not use valve lifters that were dropped or otherwise exposed to strong impacts.

Measure all the valve clearances. <Ref. to INSPECTION , Valve Clearance .>
NOTE: Record each valve clearance after measurement.
Remove the camshaft. <Ref. to REMOVAL , Camshaft .>
Remove the valve lifter.
Measure the thickness of valve lifter using micrometer.
