  Q: How to service and repair the Valve Stem Oil Seal on the left side on Cadillac DeVille?

  A: Place the essential tools j 38820, j 39313, j 43059, j 44211, j 44214 on the table to service the Valve Stem Oil Seal of the left side. Start by taking out the left Camshafts and mount the vehicle properly. Disconnect the Oil Pan from the transaxle case before taking out the torque converter cover. Install the j 44214 tool and decrease the height of the vehicle. Taking proper Spark Plug removal steps helps you keep the engine parts clean when servicing the target cylinder for this task. Set the j 44211 base plate over the Spark Plug hole first before adding the j 39313 and keeping the valve closed using constant air pressure. Insert the arm and swivel nut of j 44211 on the valve stud while adjusting the swivel nut just enough to reach valve locks which can be taken off with a magnet. You can detach the valve spring parts by pressing down on the arm when the swivel nut is loosened. Apply the j 38820 to remove the old Valve Stem Oil Seal and grip both pieces before checking the valve spring. The valve stem and seal area need oil before putting the j 38820 into position to twirl in the new Valve Stem Oil Seal. Position the arm over the valve components but tighten the swivel nut only enough to access the valve locks with the j 43059. Then set the valve locks into position. Retract both the swivel nut and arm from the j 44211 tool before doing the same with any other valve in need of service. Discharge the cylinder air pressure and take out j 39313 from the Spark Plug hole plus j 44211 base plate to mount the new Spark Plug. Work through all remaining cylinders according to procedure and finally install the left camshafts before raising and supporting the vehicle once more to uninstall the j 44214. Place the torque converter cover before fastening the Oil Pan to transaxle brace using a torque of 50 nm (37 ft. Lbs.) and letting the vehicle return to its original position.
