2004 Chevrolet Corvette Rocker Arm Parts Questions & Experts Answers

• Q: How to replace the valve rocker arm and push rods on 2004 Chevrolet Corvette?

  A: Start by taking away the valve Rocker Arm covers then organize the valve rocker arms together with valve pushrods and pivot support on a rack for restocking them back to their initial positions. The procedure starts by removing all valve Rocker Arm bolts before extracting the valve rocker arms together with the valve Rocker Arm pivot support while taking out the pushrods. When reinstalling the valve rocker arms and pushrods as reusables you must return them to their factory-installed orientation. Clean engine oil will be used to lubricate both valve rocker arms and pushrods and the flange of the valve Rocker Arm bolts. After setting the pushrods within valve lifter sockets place the valve Rocker Arm pivot support then verify proper Pushrod position in the rocker arms. Leave the rocker arms and their bolts loose at this time. Turn the Crankshaft until the number one piston reaches the top dead center of compression stroke while aligning the Crankshaft sprocket key with the 1:30 point. The number one firing position requires that technicians tighten exhaust valve Rocker Arm bolts 1, 2, 7, and 8 to 30 nm (22 ft. Lbs.) and intake valve Rocker Arm bolts 1, 3, 4, and 5 to 30 nm (22 ft. Lbs.). The Crankshaft requires a 360-degree rotation after which exhaust valve Rocker Arm bolts 3, 4, 5, and 6 need tightening to 30 nm (22 ft. Lbs.), while the intake valve Rocker Arm bolts 2, 6, 7, and 8 must also be torqued to 30 nm (22 ft. Lbs.). The final task involves installation of the valve Rocker Arm covers.
