  Q: How to replace the valve stem oil seal and valve spring with a Rocker Shaft Spring Kit on Chevrolet Silverado 1500?

  A: For Valve Stem Oil Seal and valve spring replacement you need first to take out needed valve Rocker Arms and Spark Plugs. Put the j 22794 (Spark Plug Port Adapter) into the Spark Plug hole then attach a shop air supply line and blow compressed air to keep the valves stable. To take out one valve spring you need to place a flat washer onto the bolt first then fasten the bolt and Rocker Arm. Watch out because strong pressure in the valve spring may launch it out forcefully. Apply the j 5892-d (Valve Spring Compressor) to the washer on the Rocker Arm bolt with its slotted end before applying steady pressure to the valve spring until you can access the valve keys. The j 38606 tool must be used when valve spring engagement needs adjustment. Pull off valve keys using correct procedures while gently letting tension off valve springs and taking out both j 5892-d and j 38606 tools. First you must pull out the Valve Stem Oil Seal and then continue with the valve spring and valve spring cap. Put the valve through its designated guide and add the suitable Valve Stem Oil Seal during preparation. Both parts should receive lubrication before any other steps. Use the j 42073 (Valve Stem Oil Seal Installer) to place the Valve Stem Oil Seal on the guide at 1-2 mm from the guide surface. After adding the valve spring cap and valve spring put the j 5892-d over them to compress the spring until you reach this key valve position. Use the j 38606 as your alternative tool when valve clearance becomes narrower than standard specifications. Place the valve stem o-ring seal and keys in position before you release valve pressure. Keep everything in position by using grease. Check the valve stem keys are in position before taking out the j 5892-d or j 38606. Tap the valve stem lightly if required. As the last step put back the valve rocker arms replace the spark plugs and install the j 22794.
