2008 Chevrolet Equinox 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 2008 Chevrolet Equinox?

  A: To work on valve parts a technician needs to use the Spark Plug port adapter (J 22794) and valve spring compressor (J 38606). You need to take out both the Rocker Arm and the Spark Plug at first. You need to turn the engine until the Piston reaches its highest position at top dead center to stop the valve from dropping inside the chamber before unscrewing the valve keys. Install the Spark Plug port adapter (J 22794) into the Spark Plug opening then blow air to hold the valves steady. Press the valve spring compressor (J 38606) to compress the valve spring then unfasten the three valve keys followed by removing the valve spring cap and valve spring itself. Check if the valve spring shows any damage and order a new one. After that, take out the spring seat and valve guide seal. Use the tool to push the new valve guide seal and spring seat onto the boss at valve guide location before fitting both valve parts in order. Press the valve spring compressor tool (J 38606) one more time to install both valve keys while using valve spring grease if necessary. To let out the valve spring you must remove the valve spring compressor (J 38606) part and confirm that the valve keys sit firmly in position. To finish unplug the Spark Plug port adapter (J 22794) under low pressure and replace the Rocker Arm and Spark Plug.
