2010 Buick Lucerne Parts Questions & Experts Answers

• Q: How to replace the valve stem oil seal and valve spring with a Rocker Shaft Spring Kit on 2010 Buick Lucerne?

  A: You need to put the Piston at top dead center position before the valve work to avoid dropping it into the cylinder. Before removing the Spark Plug wire you need to make it loose and clean the recess space around it. Remove both parts first the Spark Plug then the Rocker Arm. Connect the Spark Plug port adapter at (J 22794) inside the Spark Plug port and blow air to keep the valve steady. Push the valve spring down with valve spring compressor (J 5892-D) and valve spring compressor adapter (EN-47823). Take off the valve spring cap keys, valve cap, valve spring and Valve Stem Oil Seal. Apply clean engine oil to the valve stem and position the appropriate black and brown seals before installing the top valve spring parts. Reposition both valve spring parts followed by valve spring compression with the valve spring compressor (J 5892-D) and valve spring compressor adapter (EN-47823). Place the valve caps with grease if needed to secure each one onto its seat. Let compressed air out while you take the Spark Plug port adapter j 22794 from the Spark Plug opening. Rephrase the valve spring before placing back the Rocker Arm and Spark Plug.
