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

In order to service and repair the Valve Stem Oil Seal and replace the Valve Stem Oil Seal and valve spring, one has to remove the valve Rocker Arm and the Spark Plug. Locate the j 22794 (Spark Plug Port Adapter) and insert it into the Spark Plug hole while connecting an Air Hose to it. Tap the end of the valve stem with a plastic face hammer to remove any varnish that may be on the valve stems keys and then use the j 38606 (Valve Spring Compressor) to compress the valve spring and take the valve stem keys off. Carefully free up the tension on the valve spring and then remove the j 38606, the valve spring cap, the valve spring and the Valve Stem Oil Seal and shim. Clean the cylinder head valve spring seat or the shim area before you reinstall a new Valve Stem Oil Seal and shim, making sure that it is properly aligned and positioned in order to avoid additional oil consumption and abnormally high emissions from the vehicle. Apply clean engine oil to lubricate the valve guide and Valve Stem Oil Seal, next install the Valve Stem Oil Seal onto the valve stem by pushing it down until it touches the valve guide. Attach the valve spring to j 38606, compress it, reinstall it back to the cylinder head, with valve spring cap and valve stem keys, using grease to hold the keys. Carefully retract the valve spring pressure so that the keys seat perfectly into the groove of the valve stem and tap the end of the valve stem with a plastic faced hammer if needed. Detach and detach air supply from the j 22794 and remove it off from the Spark Plug hole. Measure the height of the valve spring installed. If it is more than 46.25mm and 1:82 in install a valve spring shim of about 0:5mm thickness and 0:02 in do not shim the valve spring to achieve less than the specified height. Finally, tighten the Spark Plug back in place, and valve rocker arms.
