Yes, a faulty PCV valve can indeed cause oil consumption. The Positive Crankcase Ventilation (PCV) valve helps manage crankcase pressure and recirculate gases. When it’s faulty, it can cause oil to be sucked into the intake manifold, leading to increased oil consumption and potentially noticeable smoke from the exhaust. Replacing a malfunctioning PCV valve is a relatively inexpensive fix that can prevent further engine damage and maintain optimal performance.
