• Q: How to service and repair the Valve Stem Oil Seal on 2001 Buick LeSabre?

  A: You need three tools to fix the Valve Stem Oil Seal: break out the Spark Plug port adapter (J 22794), valve spring compressor (J 38606), and valve seal installation tool (J 42863). Take off the Rocker Arm parts along with the spark plugs first. Spin the engine to keep the piston at the upper most position before entering the cylinder to avoid valve damage. The Spark Plug port adapter (J 22794) fits into the cylinder head to block valve movement as compressed air fills the chamber. Use the valve spring compressor j 38606 to press down on the valve spring before taking out the keys valve cap and the spring. Unseal the bottom part of the seal to take out the Valve Stem Oil Seal. To avoid oil seal damage when placing it on the valve stem use only manual pressure while inserting the valve seal installation tool (J 42863). The valve seal installation tool helps position the valve stem seal onto the guide after you press it with the tool. To complete installation put on the valve spring using the valve spring compressor. Place each key in its valve position and follow this method for the rest of the valves. To complete the process you need to deactivate the cylinder pressure then install the Spark Plug by using the Spark Plug port adapter (J 22794).
