2005 Buick LeSabre Valve Stem Oil Seal Parts and Q&A

• Q: How to service and repair the valve guide seal, replace the valve stem oil seal, and valve spring on 2005 Buick LeSabre?

  A: You need three important tools before fixing a Valve Stem Oil Seal and Valve Stem Oil Seal together with the valve spring: spark plug port adapter (J 22794), valve spring compressor (J 38606), and valve stem seal installer (J 42863). Start the repair by taking off Rocker Arm assemblies and removing the spark plugs. Turn the engine with the valve service cylinder first until its piston sits at the highest point of the cycle to avoid valve accidents. You should insert the Spark Plug port adapter (J 22794) into the cylinder head while compressed air fills the chamber to keep the valves shut. Drop the valve spring at its tip with the valve spring compressor (J 38606) while you remove valve keys valve cap and valve spring. Push the seal base upward toward the bottom to take out the Valve Stem Oil Seal. To install the oil seal properly, set it onto the valve stem so it contacts the valve guide before using the valve stem seal installer (J 42863) to apply gentle fitting pressure. Begin by inserting the Valve Stem Oil Seal with the valve stem seal installer (J 42863) on the valve guide. Next employ the valve spring compressor (J 38606) to set up valve spring and valve cap plus their keys. Apply these procedures to every valve before you depresurize the cylinder and detach the Spark Plug port adapter (J 22794). Install the Spark Plug along with the valve Rocker Arm components.
