9. Valve tappets should be selected in the following 

manner.
(1) Remove the valve tappet and measure its 

thickness.

(2) Calculate the correct thickness for a new valve 

tappet as follows that achieves the standard 
valve clearance.

A: Thickness of new valve tappet
B: Thickness of old valve tappet
C: Measured valve clearance
Equation:
Intake valve A = B + (C 

− 0.22 mm)

Exhaust valve A = B + (C 

− 0.30 mm)

For removal and installation procedures for the valve 
tappet, refer to "CAMSHAFT REMOVAL AND 
INSTALLATION."
(Refer to Camshaft Removal and Installa-
