How to replace the PCV valve on Buick Regal?

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.

Buick Regal PCV Valve

Engine control and emissions in Buick Regal vehicles are made possible by a PCV Valve that also boosts the performance of the automobile. Since the PCV Valve channels gases from the crankcase back to the combustion chambers where they are burnt, it helps in preventing environmental pollution and, formation of oil sludge. Being a function of intake manifold vacuum conditions, the PCV Valve shuts down the gas flow at idle position and opens at the time when loads are being imposed on the crankcase without interference with the engine operations. Also, the PCV Valve performs the function of a flame arrester and may help to increase the power of the engine through compression. Maintenance and inspections are suggested from time to time in order to prevent cases of having to spend a lot of cash just to repair the car and to make sure that the car is performing as it is expected to.

Each OEM Buick Regal 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.
