  Q: How to service and repair the Valve Stem Oil Seal on GMC Savana 1500?

  A: Start the Valve Stem Oil Seal work by removing the valve Rocker Arm cover and then taking out the needed valve rocker arms along with the Spark Plugs. Affix the j 22794 adapter into the Spark Plug opening and link a compressed air hose to start the valve retention function. Place a flat washer onto the bolt before returning the bolt into the valve Rocker Arm bolt hole to access the valve spring that needs removal. Take precautions since valve springs under compression have strong pushing power. Fit the j 5892-d valve spring compressor base into position under the washer on top of the valve Rocker Arm bolt. Slowly apply pressure on the valve spring until the valve keys become visible. When needed apply the j 38606 valve spring compressor tool for valve engagement. After dropping valve keys and controlling valve spring tension you should take off the j 5892-d or j 38606 then remove both valve spring cap and spring. Before assembly set the proper valve guide seal, lubricate both parts and put the seal onto the valve stem. Secure the valve guide seal onto the valve guide using the j 42073 tool with a seal gap of 1 to 2 millimeters between both components. After adding the valve spring and valve spring cap parts put the j 5892-d or j 38606 tool back to compress the valve spring when necessary. Apply grease between valve stem keys as you insert both parts into their positions. Lower the valve spring pressure slowly while making sure the valve keys enter the spring cap properly to prevent motor harm. Put back the spark plugs along with valve rocker arms and valve Rocker Arm cover after removing tool j 22794.
