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

Start the Valve Stem Oil Seal and valve spring replacement when the Piston stands at its highest position in the working cylinder because this keeps the valve from dropping inside. Start by unscrewing the Spark Plug then clean its recess of dust before taking off the Spark Plug piece. Next, remove the Rocker Arm. Plug the Spark Plug port adapter into its regular spot and use compressed air to keep the valve where it should be. Press the valve spring into place using the valve spring compressor (J 5892-D) with valve spring compressor adapter (EN-47823) installed. Mount a valve spring compressor after removing valve spring cap keys and incrementally removing the valve cap, valve spring, and Valve Stem Oil Seal. When installing the valve stem you should apply engine oil then place the appropriate oil seal properly (use the black seal for intake and brown seal for exhaust). Install the valve spring components and pressurize the valve spring using the previous tools to its factory position. Put the valve cap keys into place and use grease to secure them if needed while confirming good engagement. Air pressure removal enables you to extract the Spark Plug port adapter (J 22794). After installation put back the Rocker Arm and Spark Plug.
