  Q: What tools are required to service and repair the Rocker Shaft Spring Kit and replace the Valve Stem Oil Seal on Chevrolet Express 1500?

  A: To service and repair the valve spring and replace the Valve Stem Oil Seal, the following tools are required: service of the valve spring requires j22794 Spark Plug port adapter and j38606 valve spring compressor and j42078 Valve Stem Oil Seal installer. First disconnect the Spark Plug wire at the Spark Plug while twisting each plug wire boot by 1/2 turn then gently extract the wire through the boot. Engine temperature at room level enables Spark Plug removal after turning each plug 1 or 2 rotations counterclockwise and cleaning the Spark Plug with brushing or compressed air until complete removal. Use the Spark Plug port adapter (J22794) to insert into the Spark Plug hole. Then connect an air hose for compressed air to keep the valves stationary. The valve spring compressor (J38606) helps compress the valve spring until you can remove the valve stem keys and then slowly release the valve spring tension before removing the compressor. The valve spring cap must be unscrewed while you remove the valve spring and Valve Stem Oil Seal as well as the shim from the assembly. During installation start by cleaning the cylinder head valve spring seat along with the shim area before applying clean engine oil to both the valve guide and Valve Stem Oil Seal. Then install the Valve Stem Oil Seal followed by the shim. To install the valve spring and valve spring cap position the valve spring compressor (J38606) to compress the spring while inserting the valve keys seated in their proper groove on the valve stem. Use grease to hold the keys in position. Use the valve spring compressor to lower pressure before removing the compressor device and hit the valve stem's end using a plastic-faced hammer as needed to correctly position the valve keys. Finally, remove the Spark Plug port adapter (J22794), hand start the Spark Plug, and tighten it to 15 nm (11 ft. Lbs.)after setting the Spark Plug wires at the Ignition Coil and Spark Plug the installation process should finish with pushing each boot sideward to confirm proper fitment. The last step involves reinstalling the valve Rocker Arm.
