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

  A: You need to start your work by removing the valve Rocker Arm covers from left and right sides while also taking out the valve rocker arms and spark plugs. Slot the j 22794 (Spark Plug Port Adapter) into the Spark Plug opening and link a shop air hose. Use compressed air to prevent valve movement during service. Position a flat washer on a valve Rocker Arm bolt before inserting it into the bolt hole of the valve spring to be removed. Valve springs come out forcefully when using valve spring compressor because these units create strong resistance to their high compression load during valve work. Insert the j 5892-d slot to the valve spring plate washer then exert constant force to make the valve keys accessible. it is necessary to replace the j 38606 valve spring compressor if the j 5892-d does not fit. Insert the j 38606 and make sure its jaws grip the valve spring tightly to prevent slipping or damaging it. After releasing valve spring tension you must take out first the j 5892-d then j 38606 tool along with its components including valve spring cap and valve spring. Install the Valve Stem Oil Seal correctly by applying engine oil on it and valve guide as well as using the j 42073 device. Position the seal on the valve guide with a 1-2 millimeter gap. Reinstate the valve spring and valve spring cap before compressing the valve spring using the j 5892-d or j 38606 if necessary. Apply grease to the valve stem keys and place them in their positions before lowering the spring pressure to achieve the right fit. Complete the process by taking out the j 5892-d or j 38606 devices while verifying the proper position of valve stem keys before using the tool to tap the valve stem when needed.
