Buick Century PCV Valve
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.
Each OEM Buick Century PCV Valve 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 replace the PCV valve on Buick Century?A: Replace the PCV valve every 30,000 miles (48,000 km). The breather filter, located in the air cleaner on equipped models, is replaced when the air cleaner element is replaced. For V6 engines, the PCV valve is located in the right-hand valve cover on 1975-80 models. On 1981-87 models, the PCV valve is located in the rear of the intake manifold. For V8 engines, the PCV valve is located in one of the valve covers depending on the engine. To remove and install, pull the PCV valve and hose straight out of the valve cover or manifold. Use a pair of pliers to slide the hose clamp, if equipped back down the hose and off the valve connector. Twist the valve gently to loosen it from the hose, then remove. Inspect the hose and valve cover grommet, and replace if they are hard, brittle or cracked. Clean the hose with solvent if it is clogged. Install the valve into the hose, making sure it seats fully in the hose. Attach the hose clamp, if equipped around the valve assembly.
