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. 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. Install the PCV valve in the grommet, making sure the valve seats fully in the cover grommet.
