Removal Procedure

WARNING: This page is about a different variant/trim than selected.
    IMPORTANT:
    • Before you remove the valve locks, rotate the engine so that the piston in the cylinder you are working on is at top dead center (TDC). This will eliminate the possibility of the valve accidentally falling inside the cylinder.
    • Break the spark plug loose, and clean any dirt and debris from the spark plug recess area before removing.
  1. Remove the spark plug. Refer to Spark Plug Replacement in Engine Controls - 3.5L.
  2. Remove the rocker arm. Refer to Valve Rocker Arm and Push Rod Replacement .
  3. Install the J 22794  into the spark plug port. See Special Tools . Apply compressed air in order to hold the valves in place.
