• Q: How to replace the Rocker Shaft Spring Kit and valve stem oil seal on 2004 Chevrolet Silverado 3500?

  A: Begin valve work by removing both the valve Rocker Arm and Spark Plug wire at the Spark Plug. Rotate each plug wire boot one-half turn counterclockwise and lift only the boot part. Take off spark plugs from the Cylinder Head while the engine is cool by first turning them 1 or 2 times only. Then clean dirt particles from the Spark Plug using a soft brush or forced air. Insert the j 22794 Spark Plug port adapter and connect an Air Hose to hold the valves steady afterward. Put on the j 38606 valve spring compressor (J 38606) to compress the valve spring. Then dislodge the valve stem keys and relax the valve spring pressure carefully. Take away the valve spring cap and valve spring first then detach the j 38606 and remove the Valve Stem Oil Seal and shim one by one (1, 5). Clean the Cylinder Head space and install the Valve Stem Oil Seal and its support (1, 5) using clean engine oil. Place the valve spring and valve spring cap (2, 7) afterwards. Set the valve keys in position with grease after compressing the valve spring using j 38606 and adjusting it on the valve stem seat groove. Use j 38606 to compress the valve spring then hit the plastic side of the valve stem with a plastic head hammer to lock the keys in place. After taking out j 22794 from the Spark Plug port start the Spark Plug by hand and tighten it to 15 nm (11 ft. Pounds) before connecting Spark Plug Wires properly to each terminal at the Ignition Coil and Spark Plug. Complete the procedure by placing back the valve Rocker Arm.
