Oldsmobile Omega Pushrod

The Oldsmobile Omega Pushrod provides reliable valve timing. It uses the camshaft motion to transfer the motion to the cylinder head so that the intake and exhaust valves can open and close at the appropriate time. Inside this OHV layout, the cam is low in the block, lifters ride the lobes, a thin Pushrod runs up through the head, and a rocker arm tips the valve sealing the combustion to build proper compression and power in each cylinder. Earlier and later versions of the Oldsmobile Omega applied this simple single Pushrod per valve design, which was simpler than the overhead cam alternatives of other brands. Though the basic design remained the same, slight improvements in metallurgy and oiling were made in an effort to reduce wear that can cause the lash to enlarge. With extra clearance, components slam together, hammering on the Pushrod until it bends, causing noisy ticking sounds, misfires, or even piston contact. When valve springs get weakened by heat and mileage, they can float at high rpm, which is another condition that puts stress on the Pushrod and rocker pair. Routine checks of the lashes and healthy spring pressures keep the system stable, maintaining the crisp breathing that gives an Oldsmobile V8 or V6 its smooth pull. Thanks to this tried and tested hardware, the final Omega generations still delivered reliable, low-maintenance performance.

Each OEM Oldsmobile Omega Pushrod 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.

    Q: How to reinstall Pushrod, Rocker Arm and Rocker Shaft Spring Kit 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.
