2. Check only the valves indicated.
   1. Using a feeler gauge, measure the clearance between the valve lifter and camshaft.
   2. Record the out-of specification valve clearance measurements. They will be used later to determine the required replacement valve lifters.

      Valve clearance (Cold): 

      Intake 0.15 - 0.25 mm (0.0059 - 0.0098 in.) 

      Exhaust 0.25 - 0.35 mm (0.0098 - 0.0138 in.)

10. Remove the valve lifters.
11. Using a micrometer, measure the thickness of the removed valve lifters.
12. Calculate the thickness of a new lifter so that the valve clearance comes within the specified value.

    Specified valve: 

    Intake A = B + (C - 0.20 mm (0.0079 in.)) 

    Exhaust A = B + (C - 0.30 mm (0.0118 in.)) 

    VALVE CLEARANCE THICKNESS
    
    

    A	Thickness of new lifter
    B	Thickness of used lifter
    C	Measured valve clearance

    HINT:

    • Select a new lifter with a thickness as close as possible to the calculated values.
    • Lifter are available in 35 sizes in increments of 0.020 mm (0.0008 in.), from 5.060 mm (0.1992 in.) to 5.740 mm (0.2260 in.).
