Before you work on fitting a new valve stem oil seal and spring you must first take off the valve
Rocker Arm cover set. First remove the Rocker Arm cover then take out the Rocker Arm and push rod before working on the
Spark Plug. Insert the j 23590 (Spark Plug Port Adapter) into its place and use a compressed air tool to stop valves from moving. Set the j 38606 (Valve Spring Compressor) to the valve spring and actuate it. You must first release its locks before pulling out the valve spring and cap and then removing the valve stem oil seal. Check for damages on the valve spring such as bends, cracks or breaks and order a replacement part if needed. Begin by placing the oil seal onto the stem until it touches the valve guide. Do not exert excessive force as this can harm the components. Drive the j 42863 valve stem seal installation tool onto the valve guide until it reaches the valve spring seating. Return the j 38606 to its placement on the valve spring while holding it compressed. Set the valve assembly in place beginning from the valve spring to locks making sure all components properly interact. Lower the valve spring then lower the air pressure while pulling out the j 23590 tool. Put the Spark Plug back while placing the push rod then valve Rocker Arm and valve Rocker Arm cover into position.
