  Q: How to service and repair the Rocker Shaft Spring Kit and Valve Stem Oil Seal on Cadillac DTS?

  A:

  Start the valve guide seal repair process by removing both right Camshafts and supporting the vehicle at its raised position. Take these two elements out first in this order: the engine Oil Pan brace and the transaxle case torque converter cover. Put on the flywheel holder (J44214) first and drop the car afterward. You should sanitize the Spark Plug area first before taking the Spark Plug out of the engine service cylinder. Set the on-vehicle valve spring compressor base plate into the Spark Plug hole while keeping the valve shut using steady compressed air through the Spark Plug port adapter (J39313). Bring the swivel nut of the valve spring compressor j44211 next to the valve stud and attach them both before you tighten the swivel nut enough to access the valve locks. Use a magnet tool to take out these valves. Uncork the swivel nut to turn the arm around then extract the valve spring retainer and valve spring. The valve stem seal remover and installer (J38820) tool helps you remove the old valve stem seal and grip the assembly. You should discard the old seal and check the valve spring. Apply new seal by turning the valve stem seal remover and installer (J38820) while the valve stem and seal get oily treatment with engine oil. Push the retaining arm over the valve components and fasten the nut just enough to set the valve locks as you move the valve retainer remover/installer (J43059). Unfasten the swivel nut and arm from the on-vehicle valve spring compressor (J44211) device. Empty the air pressure and take off the adapter (J39313) and base plate from the Spark Plug hole. Put the new Spark Plug in place and do the same procedures at all remaining cylinders during service. Complete the procedure by reinserting the camshafts rightside up and then placing the vehicle in its elevated position. Then take away the flywheel holder (J44214), attach the torque converter cover, and fasten the Oil Pan to transaxle brace through bolt tightening at 50 nm (37 ft. Lbs.). Finally, lower the vehicle.
