You need to remove the valve rocker arms and the spark plugs, install the J 22794 into the spark plug hole and apply compressed air to hold the valves in place. Install the valve rocker arm nut, and use the J 5892-D to compress the valve spring, and the J 38606 if clearance does not permit the use of J 5892-D. Remove the valve stem keys, carefully release the valve spring tension and remove the J 5892-D or the J 38606, the valve spring cap and valve spring, and the valve stem oil seal.
