The PCV valve on the 2012 Buick LaCrosse is located on the rear cylinder valve cover. It's on the right side of the engine, on the driver side of the engine bay. The positive crankcase ventilation (PCV) valve and hose connect the engine crankcase. It is connected where the crankshaft is installed, to the intake manifold. It plays a very important role as it allows the lower half of the engine to release gases and pressure when the engine is in use. The average cost for a Buick LaCrosse PCV valve replacement is between $55 and $85 including both the costs of labor and parts required for the job.
