• Q: How to replace the pushrod and valve rocker arm on 2002 Cadillac Escalade?

  A: Start by removing the valve Rocker Arm cover to place all valve rocker arms pushrods and pivot support on a rack for future reinstallation according to their original locations. You must begin by removing the valve Rocker Arm bolt together with the valve rocker arms and the valve Rocker Arm pivot support as well as the pushrods. Before using the valve rocker arms and pushrods a second time you must clean them while inspecting all components to properly reinstall them where they originally belonged. Clean engine oil serves to lubricate both valve rocker arms and pushrods while flange lubrication needs to be applied to the bolts of the valve Rocker Arm. Begin by installing the valve Rocker Arm pivot support as the pushrods should properly enter the valve lifter sockets before addition of the pushrods which need proper seating within the Rocker Arm ends before the Rocker Arm bolts get tightened. After installing the rocker arms and bolts proceed to rotate the Crankshaft until the number one Piston reaches top dead center (TDC) of compression stroke positioning the cylinder number one rocker arms off lobe lift and the Crankshaft sprocket key at the 1:30 position. The engine needs to remain in the number one firing position to tighten bolt 1, 2, 7, 8 exhaust Rocker Arm bolts to 30 nm (22 ft. Lbs.) and bolt 1, 3, 4, 5 intake bolts to 30 nm (22 ft. Lbs.). Tighten valve Rocker Arm bolts leading to cylinders 3-6 and 7-8 exhaust to specifications of 30 nm while tightening bolts of cylinders 2-5 and 7-8 intake to 30 nm after the Crankshaft completes a 360-degree rotation. Complete the valve Rocker Arm cover installation as the last step.
