  Q: What tools are required to service and repair the valve guide seal, replace the valve stem oil seal, and valve spring on Chevrolet Silverado 3500?

  A:

  The necessary tools include a Spark Plug port adapter (J 22794) and valve spring compressor (J 38606) to service and repair the Valve Stem Oil Seal and replace the Valve Stem Oil Seal as well as valve spring. First disconnect the Rocker Arm and take off the Spark Plug wire by twisting its boot one-half turn and gently pulling the wire away from the Spark Plug. Maintain engine room temperature when detaching spark plugs because loosening them slightly before blowing away dust with an air tool ensures effective cleaning. Fit the Spark Plug port adapter j 22794 into the Spark Plug hole as you apply compressed air through an air hose and connect it to the adapter to keep the valves secure in place. You can compress the valve spring using the valve spring compressor j 38606 before taking out valve stem keys. Then let the valve spring tension go gradually before taking off the compressor. To continue the process take off the valve spring cap then the valve spring and Valve Stem Oil Seal plus shim. Apply clean engine oil to the valve guide and seal before placing the Valve Stem Oil Seal and shim. Insert the valve spring into position while placing valve spring cap on top. Depress the valve spring using valve spring compressor (J 38606) before installing valve keys which need grease for support while checking their correct position between valve stem grooves. Slowly open the valve spring pressure when the keys hold position then disconnect the compressor while giving soft hammer taps to secure the valve stem keys. Insert the Spark Plug into its port manually before this component (J 22794) and tighten to 15 nm (11 ft. Lbs.) torque. After placing the Spark Plug Wires from ignition coil to Spark Plug check each wire connection by pushing side-to-side around the boot ends. Reinstall loosely fastened boots after this last step when you reinstall the Rocker Arm.
