When the crankcase ventilation valve in your BMW fails, it can lead to very serious engine issues that can compromise your safety and your driving experience. This is because the crankcase ventilation valve regulates the air that goes into the engine and helps prevent pressure buildup. If you’ve noticed your BMW acting strange with symptoms like high oil consumption, smoke from the exhaust, or poor acceleration, it’s time to have your crankcase ventilation system inspected by professionals.
If your BMW begins to consistently act up to the point that it isn’t starting or driving reliably, you may need to look into the possibility that the crankcase ventilation system is failing in some way and get it checked as soon as possible. Hopefully, if you catch the problem on time, it can be a simple repair rather than a severe issue.
This is where we come in, at Dieter’s Porsche & BMW Service, we specialize in BMW crankcase repairs and understand that BMWs require very specialized care, so let us guide you through everything you need to know about crankcase ventilation malfunction.
Crankcase Ventilation Valve 101
Before we dive into the specifics of crankcase ventilation valve malfunction, let’s talk about the basics, which is: what is the crankcase ventilation valve?
The crankcase ventilation valve is part of your BMW’s engine breather system, which means it regulates the air that enters the engine for combustion. Because of its heavy duty use, it’s designed to withstand high pressure and extreme temperatures, but if it malfunctions for one reason or another, it can cause problems for your BMW.
Spotting A Malfunctioning Crankcase Valve
Your BMW has ways of letting you know when there’s an issue with the crankcase ventilation valve and other components, here are some common signs and why they happen:
- You’re using too much oil: if you notice your gas tank is emptying quicker than usual, this is one of the earliest signs of a malfunctioning crankcase ventilation valve.
- Your engine isn’t working as it should: your car might feel as if the engine is shaking or it isn’t accelerating correctly, this might be because of an imbalance in the chemical compounds in the engine.
- There’s white smoke coming from the engine: if you see white smoke coming from your BMW’s engine, it might mean your valve has failed and is now letting oil seep into the combustion chamber.
If you do experience any of these, bring your BMW over to us at Dieter’s Porsche & BMW Service so we can properly and accurately diagnose the core issue and provide any repairs needed.
