  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 2500?

  A: For valve guide seal service and replacement of valve guide seal and valve spring you need to work with Spark Plug port adapter (J 22794) valve spring compressor (J 38606). You need to take out the valve Rocker Arm and unplug the spark wire at the Spark Plug. Turn each boot 1/2 rotation and pull only on the boot to remove it. Affix the Spark Plug port adapter (J 22794) to each cylinder at room temperature and apply gentle turning force on spark plugs to loosen them one or two revolutions. Then use compressed air or a brush to clear debris before unscrewing the plugs. Fit the Spark Plug port adapter j 22794 into Spark Plug opening and connect air hose to valve retention system. Press compressed air into Spark Plug hole to stabilize valves. Compress the valve spring using the valve spring compressor device j 38606 before removing the valve stem keys while taking care to release tension before removing the compressor completely. Now you should take out the valve spring top, valve spring, and valve guide seal with its shim. Apply oil to valve guide and valve guide seal before installing them with the valve spring in the Cylinder Head. Use the valve spring compressor (J 38606) to compress the valve spring while placing valve keys on top and then insert the valve spring and valve spring cap. After releasing valve spring pressure carefully pull out the compressor unit while using a plastic faced hammer to tap the valve stem end if the keys require seating. Reverse the Spark Plug port adapter (J 22794) and start the Spark Plug manually before tightening it to 15 nm (11 ft. Lbs.). Install the Spark Plug Wires at the Ignition Coil and onto the Spark Plug following a final check of installation quality before putting back the valve Rocker Arm.
