The PCV Valve is an important part located in Buick Century automobiles that assists in moderating exhaust and improving the efficiency of the automobile's engines. The PCV Valve is instrumental in the provision of efficiency in the functioning of the car's engine through the recycling of combustion byproduct gases such as crankcase back to the engine's combustion chambers while limiting toxic emissions. The PCV Valve works in cyclic manner depending upon the intake manifold vacuum conditions; the valve reduces the gas flow at idle situations while increases during the loaded situations to maintain the proper crankcase ventilation without hindering the engine function. Also, a PCV Valve serves the purpose of a flame arrester, and controls the proper level of ventilation, thus preventing positive pressure build-up in the crankcase. It is therefore recommended that one should service the PCV Valve from time to time in order to avoid instances of contamination of the engine oil and oil leaks, thus leading to expensive repairs and poor working of the automobile.
