  Q: How to service and repair the Rocker Shaft Spring Kit on the left side on Cadillac DeVille?

  A: Start the valve spring left repair by taking out the left Camshafts then lift the vehicle for proper access. Detach first the engine Oil Pan brace and then the transaxle case torque converter cover. Install the flywheel holder (J 44214) first then lower the vehicle to work space. Before handling the Spark Plug clean its port area to avoid getting it dirty during valve spring left side maintenance. Position the valve spring compressor base plate (J 44211) above the Spark Plug hole and put in the Spark Plug port adapter (J 39313) component. Keep pressure on the valve continuously by blowing air into the system. Insert the arm and swivel nut of the valve spring compressor (J 44211) over the respective valve stud. Tighten the swivel nut mindest to reach the valve locks which you can extract with a magnet. Turn the swivel nut counterclockwise and slide the arm toward you to release the vale spring retainer and spring from the location. When needed the valve stem seal remover and installer (J 38820) helps you grip and take out the old valve stem seal. Apply clean engine oil to both the valve stem and new seal's inner diameter before installing the new valve stem seal through the valve stem seal remover and installer (J 38820) using a twisting movement. Insert the arm back over the valve spring components and tighten the swivel nut of the valve spring compressor tool (J 44211) to let the valve locks into position while using the on-vehicle valve retainer remover/installer tool (J 43059). Reposition the arm and swivel nut of valve spring compressor j 44211 for each valve you need to service. Service all valves and take off air pressure before uninstalling the Spark Plug port adapter and base plate of the valve spring compressor. After fixing both left camshafts you need to lift the vehicle back up. Replace the flywheel holder j 44214 part before adding torque converter cover. Last step includes bolt attachment between Oil Pan and transaxle brace tightened at 50nm (37ft lbs.) followed by movement to ground position.
