Yes, a malfunctioning Positive Crankcase Ventilation PCV valve can lead to excessive oil consumption.

What It Does: The PCV valve recirculates crankcase gases back into the intake manifold, preventing excessive oil loss.
Symptoms of a Faulty PCV Valve:
Increased oil consumption
Blue smoke from the exhaust
Rough idling o r poor performance
Solution: Replacing the PCV valve is a simple and affordable fix that can resolve oil-burning issues.
