  • Tips to Identify BMW Crankcase Ventilation Valve Malfunction From Certified Mechanics in Spring

    BMW Crankcase Ventilation Valve Malfunction Sign

    BMWs are world-renowned for their high manufacturing standards and safety features for the road. In order to maintain these standards, drivers must keep a diligent maintenance schedule or else face potentially dangerous consequences. The positive crankcase ventilation valve (PCV valve) is one of these vital parts that, when neglected, may make for risky driving.

    It is crucial that you recognize the signs of PCV valve malfunction before it becomes deadly, so in this article, we’re going to give you tips that can save your BMW and keep you safe.

    The Function of Crankcase Valve in a BMW

    The purpose of a crankcase valve is to prevent engine corrosion by taking toxic fumes produced by burning fuels and redirect them into the combustion chambers in your BMW. As a result, your car needs maintenance less frequently, air pollution is reduced, and it becomes ultimately safer to drive.

    When this valve is stuck in the opened or closed position, toxic fumes are not properly ventilated, causing a wide variety of issues.

    Diagnosing Crankcase Ventilation Valve Malfunction

    While driving your BMW, you should be aware of any changes or concerning signs, especially when it comes to your PCV valve. Of the more subtle warning signs, you can expect:

    These are not dangerous symptoms on their own, and they can be indicative of several issues, but the longer these problems are neglected, the more likely it is that parts of your BMW will wear down prematurely and malfunction as well.

    In advanced cases of valve failure, you may expect more obvious symptoms to arise, including:

    • the presence of black smoke
    • engine oil leaks

    This smoke can leak into the cabin, lowering visibility and posing a choking hazard for you and your passengers. Engine oil leakage increases the likelihood of engine failure. Not only are these repairs costly, but they are dangerous, posing the threat of a total breakdown or a crash.

    Reasons Behind PCV Valve Failure

    A PCV valve may fail for several reasons. If the engine of your BMW overheats, it may crack or break the seal, preventing the valve from closing completely when it needs to. Age and normal wear also contribute to valve damage, as it does to all auto parts. Catching these problems early is key to preventing valve failure.

    Importance of PCV Valve Maintenance

    When PCV valve issues are overlooked, you know that driving becomes more precarious, but there are other factors that any driver may ignore in the moment. Foresight is beneficial, and your vigilance is vital.

    In addition to the safety risks resulting from PCV valve malfunction, consider the financial burden of extensive repairs that will be necessary when the valve causes a domino effect of failure. You will save hundreds of dollars in the long run if you keep a regular maintenance schedule. The money that you spend to keep your BMW in optimal shape is inexpensive in comparison to part replacements and repairs.

    Finally, valve maintenance has a positive impact on the environment. Toxic fumes produced by cars contribute significantly to air pollution, and we all have a duty to protect the planet that we call home.
