  A: The starting procedure for repairing valve Rocker Arm and push rod components starts with left and right valve Rocker Arm cover removal then continued with the valve Rocker Arm pedestal retaining bolts before removing the pedestal. Place all assemblies on a clean surface before storing the components in the correct order for reassembly. The next step demands removal of both Rocker Arm assembly and Pushrods you need to clean the bolts from thread adhesive and perform assessments on valve rocker arms and pushrods. The pushrods and valve Rocker Arm assembly installation process starts from adding them first followed by adding the pedestal. The bolts which secure the lower Intake Manifold to the Cylinder Head become accessible through upper Intake Manifold removal because servicing of the lower intake requires this step. Use gm p/n 12345493 (Canadian P/N 10953488) threadlocker compound together with equivalent products to cover the valve Rocker Arm bolt threads before installing the pedestal retaining bolts at 15 nm (11 ft. Lbs.) + 90 degrees using the torque angle meter (J 36660-A). The last step involves reinstalling both valve Rocker Arm covers while listening for unusual valve train sounds.
