How to service and repair the valve guide seal, replace the valve stem oil seal, and valve spring on Chevrolet Tahoe?

The first stage of work involves removing the Rocker Arm before starting the Valve Stem Oil Seal and valve spring replacement. Turn the Spark Plug wire boot 1/2 turn and gently remove it at the base. Umbuckle the spark plugs 1 or 2 turns first making sure to brush away dust when the motor is at regular room temperature. Push the j 22794 adapter into the Spark Plug hole and join it to the Air Hose while the air pressure keeps the valves in position. Use the j 38606 (Valve Spring Compressor) to compress the valve spring. Then take out valve stem keys (225) before carefully loosening valve spring tension. Take off the j 38606 device before working on the valve spring cap (224), valve spring (223), Valve Stem Oil Seal (222), and valve (228). The valve spring seat area needs cleaning, while valve guide and Valve Stem Oil Seal require engine oil lubrication. Place valves (228) into ports first then coat Valve Stem Oil Seal (222), valve spring (223), and valve spring cap (224) one after another. Use the j 38606 to squeeze the valve spring then add valve keys while applying grease on them and verifying good contact in valve stem tracking. Slowly let go of the valve spring tension while keeping the valve keys locked in position before taking out the j 38606. Gently hit the valve stem tip with a hammer made of plastic material to ensure the keys reach their proper position. Thread the j 22794 back into the Spark Plug port then turn the hand starter to light the Spark Plug before torquing it to 15 nm (11 lb ft). Push each Spark Plug wire boot gently to see if it needs replacing after you attach one end to the Ignition Coil and the other end to the Spark Plug. Finally, install the Rocker Arm.
