Buick Skylark Rocker Arm
Rocker Arm is important part of the Buick Skylark vehicle's valvetrain that helps moves the motion from the pushrod towards the intake and the exhaust of the vehicle. Normally made from stamped steel or aluminum the Rocker Arm is a transmission that translates the vertical up and down motion of the pushrod into the desired rocking movement required to open the valves. In high RPM engines aluminum is used due to its light weight whereas cast iron or forged carbon steel is used in a diesel engine due to their sturdiness. Different types of Rocker Arms have been installed in the models of Buick Skylark throughout the years depending on the sort of Traditional or roller types. Roller rockers,the use of needle bearings for a low friction characteristic is suitable for both overhead valve and overhead camshaft engines. The rocker ratio which is standard in the current engines varies between 1.5:1- 1.8:1 can multiply the amount of the camshaft lift and thus enhance performance. Higher stress is also dealt with by implementing upgraded fulcrum bearings in engines from Buick Skylark cars particularly those with high RPM.

Buick Skylark Rocker Arm Parts Questions & Experts Answers
- Q: How to reinstall valve mechanism components and replace the rocker arm,Pushrod or valve spring on Buick Skylark?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.
