How to remove and reinstall Pushrod and rocker arm assembly in V6 engine on Chevrolet Impala?

Eliminating the components should be done by first unclipping the cable from the negative terminal of a battery. Then, take off the valve cover(s) to start doing the change process as shown below; The 3 bolts of the rocker arm mounting will be loosened one by one beginning with the drivebelt end of one cylinder head without removing them all; then the rocker arms, pivot balls, and pedestals must be separated, taking careful to stock all the parts of the rocker arm individually in accurately identified plastic bags for correct refitting. The rocker arms have a pedestal mount which is secured by a metal sleeve; the parts are in more or less integrated in assembly where the bolt can be tapped out. Take out the pushrods and keep them separately using a perforated cardboard box since the intake and the exhaust pushrods may differ in size and in terms of their colour. Check rocker arms for signs of wear, cracks or damage; also check that the rollers slide smoothly, and that the holes in the pushrod ends are open. Inspect push rods for any cracks, etc., and to look for any bending try to roll them over a flat surface. For reassembly apply clean engine oil or moly-base grease to the lower ends of the pushrods and replace them on the engine block where they belong so that they snap firmly in the lifter socket. Suffice it to say that it is customary to apply moly-base grease before the engines are started on each valve stem and upper end of the pushrods, and apply clean engine oil to the pivot balls and bearing surfaces of each rocker arm prior to the oil pressure coming up. Install the rocker arms, the pivot balls; pedestals and bolts fasten them to the standard torque limit before ensuring the pushrods engage and the correct positioning of the projections on the pedestals. Last but not the least; fit back the valve covers, turn on the engine and look for any dripping of oil or any noises coming from under the valve cover.

Chevrolet Impala Rocker Arm

Chevrolet impala cars use the Rocker Arm to enable movement of the valves in the engine through the valvetrain, after receiving motion from the pushrod. Most of them are made of stamped steel or aluminum and it's function actuates the downward pushrod movement needed for the valves to be opened. In high RPM applications, the main choice for material is aluminum due to the light weight values, while cast iron or forged carbon steel is used in the case of Diesel engines. Throughout the years, Different Rocker Arms' designs used on the Chevrolet Impala models include the conventional Rocker Arms and substantially improved roller Rocker Arms. Roller rockers incorporate bearings that lessen wear so that they are able to suit the overhead valve and the overhead camshaft engines. The rocker ratio varying from 1.5:1 to 1.8:1 in modern engines increases camshaft lift and therefore increases the efficiency of the engines. Newly developed fulcrum bearings are also used to control stress in high-RPM engines and overall durability of the Rocker Arm system in Chevrolet Impala vehicles.

Each OEM Chevrolet Impala Rocker Arm we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
