  Q: How to replace the Rocker Shaft Spring Kit and valve stem oil seal on Chevrolet Astro?

  A: Start Valve Stem Oil Seal and valve spring replacement by first removing both valve Rocker Arm cover and then all necessary valve rocker arms and Spark Plugs. The Spark Plug port adapter j22794 fits into the Spark Plug hole with a shop air hose connected to keep the valves steady under compressed air pressure. Embed a flat washer on the bolt before putting the bolt into the valve Rocker Arm bolt hole that needs the valve spring removal. Take safety precautions because valve spring compressors need to apply strong force against the valve springs to avoid harm. Use the valve spring compressor (J5892-D) by inserting its tapered edge under the washer on the valve Rocker Arm bolt and gently apply force to expose the valve keys. To stop valve spring slippage use complete jaw engagement on valve spring compressor j38606 before servicing and replace the valve spring if scratching occurs. After dropping the valve keys you can ease valve spring tension and easily remove the j5892-d or j38606 compressor then fit valve spring cap and valve spring followed by Valve Stem Oil Seal . Reinstall the valve spring and spring cap onto the valve stem. Place the valve seals in their original positions. Turn back to the j5892-d tool to compress the valve spring while you can also use the j38606 if needed because of space constraints. Insert the valve stem keys with grease and let go of valve spring pressure very slowly to maintain good key positioning to prevent harm to engine parts. Verify the position of the j5892-d or j38606 while inspecting the valve stem key placement in its upper recess. Use a plastic-headed hammer to gently tap the valve stem end if desired. At last put back the spark plugs plus tighten valve rocker arms onto cylinder head while installing the valve Rocker Arm cover.
