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

  A: First uninstall the right Camshafts and lift the vehicle to reach the valve guide seal. First take out the compartment between the engine oil tank and the transaxle case then remove the torque converter cover. Place the flywheel holder item number j 44214 into position then position the vehicle down. Before taking out the Spark Plug you must clean the space around it on the service cylinder. Place the base plate of the on-vehicle valve spring compressor (J 44211) over the Spark Plug hole before inserting the Spark Plug port adapter (J 39313) and maintaining continuous air pressure on the valve through the adapter. Fit the j 44211 on-vehicle valve spring compressor arm onto the valve stud and adjust the swivel nut to set up space for removing valve locks with a magnet. Shift the swivel nut to free up the arm which enables removing the valve spring retainer and spring. Hold the valve stem with the valve stem seal remover and installer (J 38820) to take out the old seal and discard it. Oil the valve stem and seal cylinder before installing the new valve stem seal through the valve stem seal remover and installer (J 38820). Be sure to place valve locks properly with the valve retainer remover/installer (J 43059) when you put back the valve spring retainer and spring while tightening the on-vehicle valve spring compressor (J 44211) swivel nut just enough for this step. Unwind the on-vehicle valve spring compressor (J 44211) swivel nut and arm. Release air pressure from the tool then take off the Spark Plug port adapter (J 39313) from the Spark Plug hole. Install the Spark Plug after taking off the base plate of the on-vehicle valve spring compressor (J 44211). Perform these steps again for all other cylinders receiving maintenance. Then place back the proper camshafts and follow this process by raising the vehicle, taking off flywheel holder (J 44214), adding torque converter cover and connecting Oil Pan to transaxle brace after tightening bolts to 50 n.m (37 lb ft) prior to lowering the vehicle down.
