2007 GMC Acadia Valve Stem Oil Seal Parts and Q&A

• Q: How to replace the Rocker Shaft Spring Kit and Valve Stem Oil Seal on the right side on 2007 GMC Acadia?

  A: You must start by taking out the Starter motor to replace the valve stem oil seal and valve spring on the right side. Use the flying wheel holding tool en 46106 before starting work because without it you will need to take apart and rebuild the whole cam timing system. You must first remove the camshafts and rocker arms before taking out the Spark Plug from the engine's present cylinder. Attach the j 39313 adapter tool to the cylinder opening and hose it to compressed air for this operation. Place the en 46110 (On-Vehicle Valve Spring Compressor) over the cylinder and turn its valve spring compressor nut clockwise. Release the valve keepers then loosen and comedown the valve spring compression nut to extract both valve spring retainer and springs. The en 46116 tool helps you take out the valve stem seal. First install the new valve stem seals using en 46116 and then place the valve spring and valve spring retainer. Fit the en 46110 over the valve spring and secure its compressor with proper torque. Install the valve spring keepers afterwards. Unplug the j 39313 from the air supply then detach en 46110. Replace spark plugs and install rocker arms before reattaching the camshafts while taking out the en 46106 component and putting back the Starter motor.
