The internal combustion engine of your Buick could not perform the fuel compression and combustion processes if not for the one system that puts the engine to work - the ignition system. As a part of the internal combustion engine, the Buick ignition system is an assembly of parts that together could provide the accurate timing order of the burning of fuel in the engine system. The importance of the distributor to the ignition system of your vehicle is somehow similarly related to the essence of the heart to a living creature. The ignition system could not possibly function without the distributor, but other components are also vital in the operation of the entire system. The distributor for your Buick is composed of a rotor, or more commonly known as rotating motor, a distributor cap, a distributor shaft, a rotating cam, a collection of contact breakers, the centrifugal and vacuum housing units and a condenser. The Buick distributor rotor is housed inside the distributor and is covered by the distributor cap. It is installed slightly above the distributor shaft and is covered by insulators that could prevent the high voltage current from passing through the other components of the distributor. Buick distributor rotor is designed to handle the engine operation without fail. But because of the tremendous amount of electricity that it should create, its life expectancy is unavoidably shortened. If you take your Buick to a regular maintenance check, you may prolong the service life of the various important components in your Buick. If you or your auto mechanic discovered that the distributor rotor has been damaged beyond repair you should give up your old one and start looking for a quality replacement.
