You need to remove the rocker's arm, disconnect the spark plug wire at the spark plug, loosen the spark plug 1 or 2 turns, brush or air blast away any dirt or debris from around the spark plug, remove the spark plug, install the J 22794 into the spark plug hole and attach an air hose to the J 22794. Then you can apply compressed air to the J 22794 to hold the valves in place, use the J 38606 to compress the valve spring, remove the valve stem keys, carefully release the valve spring tension and remove the J 38606, the valve spring cap, the valve spring, the valve stem oil seal and the valve.
