  Q: How to replace the Rocker Shaft Spring Kit and valve stem oil seal on Chevrolet Silverado 3500?

  A:

  To fix the Valve Stem Oil Seal and valve spring you must first take off the Rocker Arm and disconnect the plug wire at the Spark Plug by turning each wire boot 1/2 and gently pulling. Following the room temperature procedure loosen spark plugs one or two turns before air blowing off debris for removal. Insert j 22794 Spark Plug port adapter into the Spark Plug hole and join an Air Hose to it before blowing compressed air through to fix the valves in position. To replace the valve stem keys without damaging the valve spring, the j 38606 valve spring compressor (J 38606) compresses the valve spring before the technician removes both keys then releases valve spring tension. Lower the j 38606 valve spring compressor and then pull off its components in this order: valve spring cap, valve spring, and Valve Stem Oil Seal and shim in sequence (1, 5). Put engine oil on the valve guide before you install the Valve Stem Oil Seal and shim (1, 5) into their places followed by the valve spring and valve spring cap . Press the valve spring until the j 38606 reaches its compression stage then position the valve keys with grease before making sure they enter the valve stem groove. Let go of spring tension on j 38606 while keeping valve keys in their slots before taking out tool. Use a plastic-faced hammer to push keys down when necessary. Install the hand-started j 22794 into the Spark Plug port and tighten to 15 nm (11 ft. Lbs.). Place the Ignition Coil Spark Plug Wires into their designated ports at the end. Connect each Spark Plug wire to its respective Spark Plug after validation. Also reinstall any loose rubber grommets during the Rocker Arm installation process.
