2004 Buick Regal 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 2004 Buick Regal?

  A: The initial step to fix and repair the Valve Stem Oil Seal and change both the Valve Stem Oil Seal and valve spring is to take out the left or right valve Rocker Arm cover. Make sure the piston in the cylinder you are working on is at the top position by turning the engine. After that, take off the valve rocker arms together with the push rods, and after that remove the Spark Plug. Put the Spark Plug port adapter (J 23590) into the Spark Plug hole, then blow compressed air to close the valves securely. Fit the valve spring compressor (J 38606) onto the valve spring and compress it in order to take out the valve locks, then remove the valve spring and cap, and afterwards, remove the Valve Stem Oil Seal. Examine the valve spring for damage, and use a new one in place of an old or damaged one. After getting the new oil seal, slide it onto the stem until it touches the valve guide, and then install it with the valve stem seal installer (J 42863). Set the valve spring compressor (J 38606) onto the valve spring, squeeze it down, and fit the valve spring and cap, then the valve locks to be sure they seat properly. After loosening the valve spring, empty the air from the Spark Plug port adapter and put the Spark Plug in place. After that, fit the push rods and valve rocker arms in place, and put on the left or right valve Rocker Arm cover.
