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

  A: Make sure the engine is rotated until the Piston in the cylinder is at top dead center before you remove the Valve Stem Oil Seal and valve spring to stop the valve from entering the cylinder. Take off the valve Rocker Arm(s) and push rod(s), then take out the Spark Plugs. Put the Spark Plug port adapter (J23590) in the Spark Plug port and use compressed air to make sure the valves stay closed. Following this, put the valve spring compressor (J38606) on the valve spring and press it down. Pull off the valve locks, and then get rid of the valve spring and cap, and then take the Valve Stem Oil Seal out. To put in the new Valve Stem Oil Seal, use your fingers to push it all the way onto the valve guide. Put the seal on the stem and press it down until the seal touches the valve guide, then use the valve stem seal installer (J42863) to fit it properly. Put the valve spring compressor (J38606) on the valve spring and compress it a second time. Install the valve spring and cap, then put the valve locks in place, making sure they are seated. Release the valve spring, let the air pressure go, and then take out the Spark Plug port adapter (J23590). Put the spark plugs and the push rod(s) and valve Rocker Arm(s) back in place to finish the procedure.
