• Q: How to replace the Rocker Shaft Spring Kit and valve stem oil seal on 2005 Chevrolet Astro?

  A: First detach the valve Rocker Arm cover then take out valve rocker arms and spark plugs before Valve Stem Oil Seal and valve spring replacement. Insert the j 22794 tool into the Spark Plug hole then link a shop hose and blow compressed air to immobilize valve movement. To take the old valve spring out you must first remove its bolt then install a flat washer on top of the bolt before putting it back in the valve Rocker Arm bolt hole. When compressing valve springs with the spring compressor tool handle them carefully because the setup produces extreme pressure that forces springs out forcefully when not managed properly. Push the j 5892-d compressor on the slotted section under the valve Rocker Arm bolt washer then apply steady force until you see the valve keys. Hold the j 38606 tightly onto the valve spring to avoid movement during compression work since any scratching will require a new valve spring. Use pliers to take out the valve keys then release valve spring tension only before you remove j 5892-d or j 38606. After loosening the valve spring cap and spring you must uninstall the Valve Stem Oil Seal. You should first set valve seals on top of the valve stem, put the spring below them and the spring cap over them. When space is tight you should employ the j 38606 to set valve spring pressure instead. Use valve stem grease to set the keys in place while you release the valve spring pressure slowly to prevent engine harm. Check the valve stem keys position then press the j 5892-d with light force until the keys lock in place. If needed tap the valve stem end gently with a plastic-headed hammer. End with the j22794 then install the spark plugs valve rocker arms and valve Rocker Arm cover.
