  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 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.
