  Q: What tools are required to service and repair the valve guide seal, replace the valve stem oil seal, and valve spring on Chevrolet Suburban 1500?

  A: For Valve Stem Oil Seal service and replacement of Valve Stem Oil Seal and valve spring the needed tools include Spark Plug port adapter (J 22794), valve spring compressor (J 38606), and Valve Stem Oil Seal installer (J 42078). Start the service by unscrewing the valve Rocker Arm and disconnecting the Spark Plug wire from its base. Remove the wire using only the boot and turn it half a turn counterclockwise. If spark plugs are removed from the Cylinder Head at normal engine temperature they can turn very easily while you rinse away debris. Take the commands and adapter j 22794 into the Spark Plug opening then connect an air hose for pressure that holds valves steady. The valve spring compressor j 38606 presses down valve springs while you extract the valve stem keys and lets you carefully relieve valve tension before taking away the compressor tool. Take off the valve spring cap and spring from the assembly. To make the first design change you must take off the Valve Stem Oil Seal plus valve spring shim. The second design needs a Valve Stem Oil Seal and shim removal. First clean the space where the valve spring seat is located before adding the valve spring shim on the initial design and the Valve Stem Oil Seal together with the second design's shim. The Valve Stem Oil Seal installer (J 42078) is not necessary for installing the second design. Position the Valve Stem Oil Seal properly on the valve guide to stop oil loss and preserve the valve parts. Apply clean oil to the valve guide before inserting the first design Valve Stem Oil Seal onto the valve stem. Place the right oil seal into position using the Valve Stem Oil Seal installer tool (J 42078). Check the space between the valve spring shim surface and the top oil seal edge to be 18.1 mm to 19.1 mm (0.712 inch to 0.752 inch). Place the valve components together with the spring compressor j 38606 and valve spring. Dust the valve heads with grease to secure them during installation. Slowly let valve spring pressure out while keeping the keys in place and take out the compressor. Strike the valve stem with a plastic head hammer if necessary to push the seat for keys properly. Use the plug spark adapter j 22794 tool to begin the spin on Spark Plug then secure it to 15 nm (11 ft.lbs) before reinstalling plug wires and coil.
