• Q: How to replace the Rocker Shaft Spring Kit and Valve Stem Oil Seal on the right side on 2005 Cadillac DeVille?

  A: A toolkit for right-side valve stem oil seal and valve spring changing includes j 38820 (Valve Stem Seal Remover and Installer) along with j 39313 (Spark Plug Port Adapter) and j 43059 (Valve Retainer Remover/Installer) and j 44211 (On-Vehicle Valve Spring Compressor) and j 44214 (Flywheel Holder). The tools required for valve stem oil seal and valve spring replacement are j 38820 (Valve Stem Seal Remover and Installer), j 39313 (Spark Plug Port Adapter), j 43059 (Valve Retainer Remover/Installer), j 44211 (On-Vehicle Valve Spring Compressor), and j 44214 (Flywheel Holder). Start by removing the right camshafts and then lift the vehicle to reach its components. First detach the brace connecting the transaxle case to the engine Oil Pan before you take off the torque converter cover. Slip the j 44214 into position before lowering the vehicle. Clean the cylinder Spark Plug recess area before removing the Spark Plug from the cylinder under service. Insert the j 39313 device into the Spark Plug hole after fitting the j 44211 base plate in position then maintain constant air pressure on the valve to prevent it from opening. Use the arm and swivel nut of the j 44211 to clasp the valve stud. Tighten the swivel nut to expose valve locks so you can remove them with a magnet. Loosen the swivel nut to remove both valve spring retainer and valve spring. Use the j 38820 valve stem seal remover and installer to remove the existing valve stem seal while discarding it before performing inspections of the valve spring. Use clean engine oil to coat the valve stem and new valve stem seal inner diameter. Then install a seal protector onto the valve stem before using the j 38820 to place the new valve stem seal. Install the valve spring retainer with its valve spring on the j 44211 then adjust the swivel nut to a tight enough position that allows valve locks placement using the j 43059. Begin by removing the j 44211 swivel nut and arm section while releasing air pressure and removing j 39313 from the Spark Plug opening. Unfasten the baseplate of the j 44211 then place back the Spark Plug. After servicing each cylinder follow the correct installation steps before reattaching both right camshafts. After raising the vehicle install the j 44214 and mount the torque converter cover while fastening the Oil Pan to transaxle brace with bolts torqued to 50 nm (37 ft. Lbs.). Finally, lower the vehicle.
