Oldsmobile Omega Rocker Arm
In Oldsmobile Omega automobiles, the Rocker Arm is an important component of the engine that enables motion to be transported from the pushrod to the valves of the intake and exhaust. Usual material is the stamped steel or aluminum, They translate the up-and-down movement of the pushrod into downward movement to open the Rocker Arm Valves. For high RPM use, aluminum is used because of the low density it possesses and cast iron or forged carbon steel for use in diesel engines. Rocker Arms in Oldsmobile Omega car models may be categorized into, the conventional metal on metal Rocker Arms and the roller Rocker Arms, which incorporated needle bearings thus were less susceptible to wear and tear. The rocker ratio which in the modern engine vary between 1.5:1 to 1.8:1 facilitates better performance by magnifying the lift of the camshaft. Consequently, the fulcrum bearings are also fitted to high RPM engines for stress control and to enhance the durability of the Rocker Arm system in Oldsmobile Omega series as well.

Oldsmobile Omega Rocker Arm Parts Questions & Experts Answers
- Q: How to reinstall valve mechanism components and replace the rocker arm,Pushrod or valve spring on Oldsmobile Omega?A: Valve mechanism components must be reinstalled to their original positions, and all removed components should be placed in a compartmented box for identification. Begin by removing the rocker arm cover. If only the pushrod is being replaced, loosen the rocker nut/bolts enough to rotate the rocker arm away from the pushrod. For replacing the rocker arm or valve spring, remove the rocker arm nut and ball, then lift off the rocker arm. Pull the pushrod out of its hole, and if the valve spring is to be removed, take out the spark plug from the cylinder being serviced. To keep the valve in place while removing the valve spring, use compressed air by attaching an air hose adapter to the spark plug hole, or if compressed air is unavailable, bring the piston to approximately 45-degrees before top dead center and feed a long piece of 1/4-inch nylon cord into the combustion chamber, leaving the end hanging out for easy removal. On early models, thread the rocker arm nut onto the rocker arm stud, position a valve spring compressor tool over the spring, and apply downward pressure to compress it. On later L4 models, install the rocker arm bolt and use a lever-type tool for compression. Compress the spring just enough to remove the valve spring retaining cups, then release the pressure. Remove the valve spring retainer, cup shield, valve spring, and valve stem oil seal, which must always be replaced when the spring locks are disturbed. Installation follows the reverse of removal, ensuring to coat the bearing surfaces of the rocker arms and balls with 'Molykote' or an equivalent before installing the rocker arms. The L4 engine valve mechanisms do not require special lash adjustment, while V6 engines necessitate lash adjustment.
