  Q: How to service and repair the Rocker Shaft Spring Kit and Valve Stem Oil Seal on GMC Jimmy?

  A: First remove the valve Rocker Arm cover and necessary valves from the engine while taking out all needed spark plugs. Load the j 22794 Spark Plug port adapter into the Spark Plug opening to maintain valve position while you attach a compressed air hose and provide air pressure to hold the valves. Place a bolt in the valve Rocker Arm bolt hole with a flat washer installed over a bolt before positioning it inside the valve Rocker Arm bolt opening. Work safely with valve springs since they hold much force; accidents can harm your body when you disturb the tension. Thread the slotted end of the j 5892-d valve spring compressor under the washer on the valve Rocker Arm bolt and gently apply pressure to make the valve keys accessible. The j 38606 valve spring compressor (J 38606) should totally fit onto the valve spring to avoid movement and damage during operation. Take off valve keys while reducing tension on the spring by the j 5892-d or j 38606 tool. After removing the parts you need to take out the valve spring cap first then the valve spring before you take off the valve stem oil seal. Place new valve seals first on the valve stem and add the valve spring afterward before installing the valve spring cap. When it comes to pressing the valve spring use j 5892-d again. J 38606 serves as an alternative option when space is constrained. Insert the valve stem keys into their spaces while pinning them in place with grease and lower the valve springs steadily to prevent engine parts from getting damaged. Take away the j 5892-d or j 38606 from the valve stem then check if the keys have their correct position. Tap the valve stem end lightly with a plastic-headed hammer if you need to. Put in spark plugs and valve rocker arms after you place the j 22794 as the last step.
