What tools are required to service and repair the valve guide seal, replace the valve stem oil seal, and valve spring on GMC Yukon?

In order to do the Valve Stem Oil Seal service, replace the Valve Stem Oil Seal, and adjust the valve spring, you will need the listed tools: j 22794 Spark Plug port adapter and j 38606 valve spring compressor. First, take off the Rocker Arm and disconnect the Spark Plug wire from the Spark Plug, twisting the boot and pulling only on the boot. Loosen the spark plugs in the Cylinder Head 1 or 2 turns with the engine cool, then clean away any dirt or debris before taking them all the way out. Put the Spark Plug port adapter (J 22794) into the Spark Plug hole, link an air hose, and use compressed air to hold the valves open. With the valve spring compressor (J 38606), squeeze the valve spring, but before removing the compressor, take the valve stem keys apart and let go of the compressed spring very carefully. You should then remove the valve spring cap, the valve spring, and the Valve Stem Oil Seal and shim. Make the area around the Cylinder Head valve spring seat or shim clean, add clean engine oil to the valve guide and Valve Stem Oil Seal, then install the Valve Stem Oil Seal and shim into place. Mount the valve spring and valve spring cap, compress the spring with the help of the valve spring compressor (J 38606), and push the valve stem keys onto the stem, covering them with grease and checking that they sit securely in the stem groove. Ease off the valve spring pressure, then take away the compressor, and if the keys need it, tap the valve stem with a tool having a plastic face. Take away the Spark Plug port adapter (J 22794) from where it is on the Spark Plug port, screw in the Spark Plug by hand, and tighten secure the Spark Plug Wires to the Ignition Coil and to the Spark Plug, making sure they are attached correctly and putting back any loose boot before putting on the Rocker Arm.
