• Q: How to replace the pushrod and valve rocker arm on 2006 Cadillac Escalade EXT?

  A: A rack will serve to keep the original positions of valley rocker arms and pushrods while you disassemble their components. To begin, remove the Rocker Arm cover while placing the rocker arms along with pushrods and pivot support into the rack. After Rocker Arm bolt uninstallation comes the removal of rocker arms and Rocker Arm pivot support followed by taking out the pushrods. Clean all rocker arms before inspecting them together with their pushrods. Engine oil lubrication should be applied to both the rocker arms and pushrods during installation and the flange of Rocker Arm bolts must receive attention for lubrication as well. Position the Rocker Arm pivot support before both ends of the pushrods and valve lifter sockets reach their fitting position but leave the Rocker Arm bolts untightened. During the procedure the motor needs to be positioned at top dead center (TDC) for compression stroke where the number one Piston rests while the Rocker Arm lobes remain inactive and the Crankshaft sprocket points at 1:30 mark. The current engine position requires torquing Exhaust Valve bolts for cylinders 1, 2, 7, 8 to 30 nm (22 ft. Lbs.) simultaneous with Intake Valve bolts for cylinders 1, 3, 4, 5 at 30 nm (22 ft. Lbs.). After turning the Crankshaft fully by 360 degrees tighten Rocker Arm bolts of cylinders 3, 4, 5 and 6 exhaust valves to 30 nm (22 ft. Lbs.) while cylinder 2, 6, 7 and 8 intake valves should be torqued to 30 nm (22 ft. Lbs.). Install the Rocker Arm cover as the last step.
