How to service and repair the Rocker Shaft Spring Kit and Valve Stem Oil Seal on GMC C2500?

Before replacing the valve stem oil seal and valve spring, take out the valve rocker arms from the Cylinder Head and the spark plugs. Slide the (J22794) into the Spark Plug hole, then use compressed air to keep the valves secured. Attach an m8 bolt (J5892-D) to the valve Rocker Arm using a washer, then use (J38606) to add more compression to the valve spring. First take out the (J21058) valve stem keys, then release the spring pressure from the valve and in the end, take the (J62681) compressor, (J38606) valve spring cap, (J28861) valve spring and (J50572) valve stem oil seal off. Take the valve spring shim out if the manual tells you to. Before anything else, put the valve spring shim in place if you have one and when assembling the valve stem oil seal onto the guide, make certain they are aligned to reduce both oil use and harm to the parts. Apply clean engine oil to the valve guide and oil seal and fit the seal over the valve stem down into position. Apply pressure on the object (J42073) to fit the oil seal into position against the valve spring shim or spring seat. After that, place the valve spring and the valve spring cap, snugly compress the valve spring using tool j5892-d or j38606 and fit the valve keys using a thin layer of grease. With the valve pressure released, see that the keys stay in place and remove (J5892-D) and (J22794) carefully. You should install the spark plugs and valve rocker arms in the final step.
