NOTE: Refer to the appropriate specification chart.
1. 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 inner diameter of the valve guides in 2 directions at the top, middle and bottom of the valve guide.
2. Measure the ball gauge with a micrometer.
3. If the valve guide is not within specifications, install a new cylinder head assembly.
