How to service and repair the valve guide seal, replace the valve stem oil seal, and valve spring on GMC Sierra 1500?

You need to remove the Rocker Arm before working on the Valve Stem Oil Seal repair and replacing Valve Stem Oil Seal and valve spring. To disconnect the Spark Plug wire gently twist each boot about 1.5 times and simply pull on the boot at its base. At room temperature take off spark plugs from engine head by turning them 1 or 2 times then clean each Spark Plug port before full removal. Put the j 22794 (Spark Plug Port Adapter) in the Spark Plug opening and connect air tubing followed by pushing compressed air against the valves to keep them steady. Lower the valve spring pressure using the j 38606 before taking out the valve stem keys (225) and gently decompressing the valve spring using the tool. Take out the valve spring cap 224, valve spring 223, Valve Stem Oil Seal 222, and the valve 228. Clean the valve seat area with oil and lubricate both the valve guide and Valve Stem Oil Seal with fresh engine oil. Insert valves (228) in their specific slots then put together Valve Stem Oil Seal (222), valve spring (223), and valve spring cap (224). Apply spring pressure through the j 38606 tool before setting the valve keys in their valve stem grooves with grease. Lower the spring pressure gently while holding the keys in position. Strike the valve stem end lightly with a plastic faced hammer if the keys need further seating work after you take off the j 38606. Fit the j 22794 into the Spark Plug port before kicking the engine to start and torquing the plug to 15 nm (11 lb ft). Check the Spark Plug wire installation into both the Ignition Coil and plug. Check all wires by applying side pressure to boot covers and fixing loose ones when found. Finally, install the Rocker Arm.
