  Q: How to replace the Rocker Shaft Spring Kit and valve stem oil seal on Buick Terraza?

  A:

  You need to put the Piston at top dead center (TDC) before Valve Stem Oil Seal and valve spring replacement because moving the valve below could damage the cylinder. Start the process by unlocking the Spark Plug and cleaning the space around the plug before taking out the Spark Plug. Rest the valve in its position using compressed air while you put the Spark Plug port adapter (J 22794) through the Spark Plug port. Use a valve spring compressor (J 5892-D) while applying pressure adapter (EN-47823) along the valve spring. Put away valve spring cap tools plus valve cap, valve spring and Valve Stem Oil Seal following valve compressing. Oil the valve stem with clean engine oil and put on the correct oil seal based on its application (black for intake and brown for exhaust). Reinstall the valve spring topped by the cap. Employ the j 5892-d and en-47823 spring compressor equipment to compress the component before adding it to the assembly. Put the valve cap keys into their slots while before tightening them apply grease for extra support. Standardize the setup to match initial specifications. Breathe out the air and take out the j 22794 tool from the Spark Plug hole before putting back the Rocker Arm and Spark Plug.
