2006 GMC Savana 3500 Rocker Arm Parts Questions & Experts Answers

• Q: How to replace the valve rocker arm and push rods on 2006 GMC Savana 3500?

  A: Start the valve Rocker Arm and pushrod replacement process by removing the valve Rocker Arm cover followed by putting the valve rocker arms and pushrods together with the pivot support on a rack to preserve their former installation. Begin by taking out the valve Rocker Arm bolts and then the valve rocker arms and the valve Rocker Arm pivot support followed by the pushrods. The technician should inspect the valve rocker arms while cleaning them. Reinstall all components by placing them back into their correct positions because the valve lash builds up naturally without requiring any adjustment step. Clean engine oil serves to lubricate both valve rocker arms and pushrods as well as the valve Rocker Arm bolt flange. Lay the valve Rocker Arm pivot support into position while the pushrods should fit into valve lifter sockets before fitting pushrods into the Rocker Arm positions without tightening the Rocker Arm bolts. At top dead center of the compression stroke on number one piston with the Crankshaft sprocket key positioned at 1:30, install the rocker arms and their corresponding bolts. You should torque valve Rocker Arm bolts to 30 nm (22 ft. Lbs.) on cylinders 1, 2, 7, 8 exhaust and cylinders 1, 3, 4, 5 intake at this specific Crankshaft position. The technician must rotate the Crankshaft by 360 degrees before applying a torque of 30 nm (22 ft. Lbs.) to valve Rocker Arm bolts. The technician must do this on cylindrical valves 3, 4, 5 and 6 exhaust and 2, 6, 7 and 8 intake. At the end of the procedure install the valve Rocker Arm cover.
