BMW Engine Misfire

The Best Repair Shop in Louisville to Repair a Crankcase Ventilation Valve Malfunction in a BMW

Posted on May 22, 2021 by smikyautomowp

BMW’s are a reputable brand with the best German engineering. They can have issues which lead to a crankcase ventilation valve failure. When you’re concerned about the health of your BMW, come to St. Matthews Imports automotive service. Our certified technicians are experts on crankcase ventilation valves and can restore your BMW to top condition.

What is the crankcase ventilation valve?

The PCV system was created to protect the car from unburned fuels that may leak from the engine. These gases can damage the environment and also make their way into the cabin of your BMW, where they would be dangerous to you and your passengers. The crankcase ventilation valve helps to eliminate these concerns.

This valve is part of a system called the Positive Crankcase Ventilation (PCV) system. It is placed under cylinders and works to remove any gases that may accumulate in the crankcase. Those gases are transported to a part of the vehicle called the intake manifold, where they are burned.

If the crankcase ventilation valve or the PCV system has problems, then it will be unable to move the accumulated gases to the intake manifold. Instead, they’ll gather in the engine system that could possibly lead to engine damage and even engine failure.

Your car may continue to drive regardless of this malfunction, but that’s not safe to do. A faulty PCV valve or crankcase ventilation valve can cause permanent damage to your BMW engine. This will lead to further expensive repairs. It’s highly recommended to get your vehicle inspected as soon as possible if you think there may be problems.

Signs Of Crankcase Ventilation Valve Malfunction

These are some symptoms that your crankcase ventilation valve may have malfunctioned.

  • Exhaust smoke: If you notice anything out of the ordinary with your exhaust pipe smoke, then it may be related to a crankcase ventilation valve malfunction. A valve failure can transport the extra gases to the combustion chamber instead of the intake manifold, which is then burned in the engine and exited out of the exhaust pipe.
  • Poor performance: Because a failing valve means that the gases are accumulating and not being removed as designed, this can affect your BMW’s performance. You may feel your engine is not performing as it used to.
  • BMW feels rough when idling: If you notice that your BMW feels rough when idling, it may signify a faulty valve. When the valve isn’t able to manage the airflow between the intake manifold and the crankcase, this rough idling is felt.
  • Engine not starting: The crankcase ventilation valve also prevents contamination and sludge buildup. A faulty valve means the gases are not being removed. This can lead to trouble when trying to start your engine.
  • Misfiring engine: When the air-to-fuel ratio is improper, then your car may produce engine misfires. A malfunctioning crankcase ventilation valve can negatively affect the air-to-fuel ratio.
  • Excessive oil consumption: You may notice that your vehicle is burning more fuel than in the past. If you suspect that your BMW is burning through more oil than normal, it is important to the health of your engine to have a professional inspect your vehicle for leaks or valve problems.
