Tacoma PreRunner Extra Cab 2WD V6-3.4L (5VZ-FE) (2000)
HINT:
-
Apply SST (B) at a slight angle on the side marked with "9" or "7", at the position shown in the illustration.
-
When SST (B) is inserted too deeply, it will get pinched by the shim. To prevent it from being stuck, insert it gently from the intake
side, at a slight angle.
4) Using a small screwdriver and magnetic finger, remove the adjusting shim.
b) Determine the replacement adjusting shim size by following the Formula or Charts:
1) Using a micrometer, measure the thickness of the removed shim.
2) Calculate the thickness of a new shim so the valve clearance comes within the specified value.
T Thickness of used shim
A Measured valve clearance
N Thickness of new shim
Intake: N = T + (A - 0.18 mm (0.007 inch))
Exhaust: N = T + (A - 0.32 mm (0.013 inch))
