OEM 2007 Buick Terraza Valve Stem Oil Seal

2007 Buick Terraza Parts Questions & Experts Answers

• Q: What tools are required to service and repair the valve guide seal, replace the valve stem oil seal, and valve spring on 2007 Buick Terraza?

  A: You need en-47823 valve spring compressor adapter and j 22794 Spark Plug port adapter plus j 5892-d valve spring compressor to service the Valve Stem Oil Seal and replace Valve Stem Oil Seal and valve spring. First turn the engine to bring the piston to the top dead center (TDC) position to avoid the valve entering the cylinder. Before taking out the Spark Plug you need to clean the area around its base. Install j 22794 into the Spark Plug opening and use compressed air to shut down the valve while keeping the j 22794 valve in position. Gently push the valve spring with the j 5892-d and en-47823 before taking out all valve spring components and the Valve Stem Oil Seal. Apply engine oil to the valve stem and put on the correct Valve Stem Oil Seal first (put black seal on intake and brown seal on exhaust). After that install the valve spring and valve cap. After using the j 5892-d and en-47823 to compress the valve spring remove its keys from both valve caps. Place the Rocker Arm and plug back into their original positions.
