How to replace the valve rocker arm and push rods on Chevrolet Corvette?

Start valve Rocker Arm and push rod replacement by removing valve Rocker Arm covers and setting valve rocker arms along with valve pushrods and pivot support into a rack for storing in their original positions. The next step is to remove both valve Rocker Arm bolts and their associated components which include valve rocker arms and valve Rocker Arm pivot support alongside pushrods. The cleaning process should precede inspection before you apply engine oil for lubrication. Apply clean engine oil to valve Rocker Arm bolt flanges and after that install the valve Rocker Arm pivot support until pushrods match the valve lifter sockets. After proper seating of the pushrods against the Rocker Arm ends, complete the installation by avoiding any bolt tightening steps. After installing the rocker arms and their bolts perform Crankshaft rotation until the number one Piston reaches top dead center compression, ensuring the first rocker arms stay off their lift positions while positioning the Crankshaft sprocket key at 1:30. Follow these specifications to tighten the exhaust Rocker Arm bolts 1, 2, 7, and 8 to 30 n.m (22 lb ft) simultaneously as well as the intake Rocker Arm bolts 1, 3, 4, and 5 to 30 n.m (22 lb ft) while the engine is in the number one firing position. The mechanics should perform a Crankshaft rotation by 360 degrees before tightening each bolt with a torque wrench setting at 30 n.m (22 lbft). The exhaust valve bolts 3, 4, 5, and 6 should have 30 n.m torque and the intake valve bolts 2, 6, 7, and 8 should reach 30 n.m (22 lbft). Under the final step precede the installation of valve Rocker Arm covers.

The Rocker Arm in Chevrolet Corvette automobiles is a crucial component of the valvetrain system It rotates the motion of the pushrod to the valves of both, intake and of the exhaust. Customarily made of stamped steel or aluminum, the Rocker Arm translates the oscillatory movement of the pushrod vertically into the required amount of force needed to lift the valves. In high RPM applications, aluminum is incorporated owing to its lightweight, while CI or forged carbon steel is implemented in other applications. Chevrolet Corvette models have adopted different Rocker Arm designs: conventional and roller types. Overhead valve as well as overhead camshaft engines benefit with roller rockers that include needle bearings for decreasing friction. The rocker ratio known to vary between 1.5 to 1.8 in modern engines escalates the camshaft lift to improve on performance. Sintered fulcrum bearings are also used in the version of the fast-rotating Corvettes to increase its durability and performance when subjected to greater loads.
