NOTE:

Refer to the appropriate Section 303-01 for the specification.

NOTE:
Valve guides tend to wear in an hourglass pattern. The ball gauge can be inserted into the combustion chamber side of the valve guide, if necessary.
Use a ball gauge to determine the inside diameter of the valve guides in 2 directions at the top, middle and bottom of the valve guide.

Measure the ball gauge with a micrometer.

If the valve guide is not within specifications, install a new cylinder head assembly.
