Yes, a faulty PCV (Positive Crankcase Ventilation) valve can cause oil burning in vehicles. This happens because a malfunctioning PCV valve may not properly regulate air flow, causing an imbalance. This imbalance can lead to oil being sucked into the combustion chamber, where it is burned along with fuel. If you notice your vehicle burning oil or emitting blue smoke, it's a good idea to check the PCV valve among other diagnostics.
