PCV Valve (Positive Crankcase Ventilation)

Some cars have a PCV (Positive Crankcase Ventilation) system and the main component is the PCV valve. Inside the engine(crankcase) byproducts and gases are released and it creates pressure, this is why its sealed in order to prevent gases from escaping into the atmosphere. This is where the PCV system comes into play.When enough pressure is created, the gases are released via the PCV valve to be burned again.

When the PCV valve starts to fail, you may notice more white fumes coming out of your exhaust pipe.  Replacing the PCV is very simple and they are very cheap. The old valve is removed and replaced with the new valve. A PCV valve that is not working properly will steadily decrease your gas mileage and destroy the engine itself if it is neglected. PCV valves should be replaced or checked every 30,000 miles.
