How to service and repair the Valve Stem Oil Seal on Chevrolet Express 3500?

Begin Valve Stem Oil Seal service by taking off valve rocker arm covers then spark plugs while wearing safety glasses. Install the Spark Plug port adapter j 22794 on top of the Spark Plug hole then apply compressed air through this adapter to clamp the valves in position. Mount the valve base nut first and use the valve spring compressor (J 5892-D) to compress the valve spring. If clearance problems appear, use the substitute valve spring compressor (J 38606) instead. Lower the valve spring compressor from the stem using keys and then relax tension before removing the j 5892-d or j 38606. Next pull the valve spring cap and valve spring out followed by the Valve Stem Oil Seal. Choose the correct Valve Stem Oil Seal according to valve guide requirements then place the valve spring on top of it. Finally, seat the valve spring cap. Squeeze the valve spring back with the j 5892-d compressor tool or j 38606 when needed before inserting the valve stem keys and holding them with grease. After loosening valve spring pressure keep the valve stem keys aligned as you take out j 5892-d or j 38606 then put in the spark plugs and valve rocker arm covers.
