  Q: How to service and repair the Valve Stem Oil Seal on Chevrolet Express 1500?

  A: Start your Valve Stem Oil Seal service by taking out the valve Rocker Arm and rotating each Spark Plug wire boot half turn before just pulling up the boot to disconnect. With a warm engine place 1 or 2 turns on each Spark Plug before removing it and clean away dirt deposits with a brush or compressed air. Put the Spark Plug port adapter (J22794) into the spark hole and connect an Air Hose before blowing compressed air into the valves for support. Begin by compressing the valve spring with valve spring compressor j38606. Afterwards remove both valve stem keys and ease off the valve spring pressure when taking the compressor out. Proceed by taking off the valve spring cap, valve spring and oil seal with shim (1,5). Before assembly apply cleaning to the valve seat area, apply engine oil to valve guide and stem components, then place oil seal and shim (1,5). Install the valve spring and valve spring cap afterward. Load the valve keys with grease then position them correctly into the groove of the valve stem. Pressurize the valve spring using the valve spring compressor tool before installing the valve keys with grease. After dismantling the valve spring compressor carefully lower the valve spring pressure while keeping the valve keys in position. Use a plastic faced hammer to tap the valve stem end when the keys need seating. Finish by firstly taking off the Spark Plug port adapter (J22794) from the Spark Plug port. Then start the Spark Plug manually and fasten it with 15 nm (11 ft. Lbs.) torque. Connect the Spark Plug Wires to the Ignition Coil and install them properly. Verify that the wires are installed correctly and replace any loose boots before adding the valve Rocker Arm.
