Removal Procedure

WARNING: This page is about a different variant/trim than selected.
  1. Remove the rocker arm. Refer to Valve Rocker Arm and Push Rod Removal .
  2. Remove the spark plug. Refer to Spark Plug Replacement .
    3. IMPORTANT: Before you remove the valve keys, rotate the engine so that the piston in the cylinder you are working on is at (TDC) top dead center. This will eliminate the possibility of the valve accidentally falling inside the cylinder.
  3. Install the J 22794  into the spark plug port. See Special Tools . Apply compressed air in order to hold the valves in place.
