The PCV valve in your car’s engine plays a vital role in preventing harmful emissions from escaping into the atmosphere when you run your vehicle. While you may not see the PCV valve or even know what it does if it fails, you can end up with several engine problems that will affect your car’s fuel economy and performance. While it’s essential to maintain regular maintenance and ensure that everything else about your car is functioning well, you must recognize signs of mechanical problems before they get worse. Here are five warning signs that your PCV valve may fail or break.
Poor Fuel Economy
Poor fuel economy is one of the most common signs that your car’s PCV valve is failing. So if you notice that your vehicle is starting to guzzle gas more than usual, it could be time to get your PCV valve checked out. While many other issues can lead to poor fuel economy, a failing PCV valve is one of the more common.
Rough Idle
Another very common sign that your car’s PCV valve is failing is a rough idle. If you notice that your car is idling roughly, it’s a good idea to take it to a mechanic to have it checked out. As with many of these signs, there are a few other potential causes of a rough idle, but a failing PCV valve is one of the most common.
Incorrect Fuel/Air Mixture
Another symptom of a failing PCV valve is an incorrect fuel/air mixture. This can cause your car to run lean, leading to engine damage. You may also notice a decrease in fuel economy and an increase in emissions. If you see any of these symptoms, it’s essential to have your car checked out by a mechanic as soon as possible.
Unusual Engine Noises
If your car’s engine starts making unusual noises, it could be a sign that the PCV valve is failing. These noises may include hissing, clicking, or ticking sounds. If you notice any of these sounds, it’s important to take your car to a mechanic as soon as possible to have it checked out.
Poor Acceleration
Another sign that your car’s PCV valve is failing is poor acceleration. If you notice that your vehicle is struggling to reach higher speeds or takes longer than usual to accelerate, it could be a sign that the PCV valve is not functioning correctly. In some cases, this can also lead to a decrease in fuel efficiency.
Your car’s PCV valve is a component that most people don’t give much thought to, but it can cause problems if it’s starting to fail. See your mechanic immediately if you notice any signs of a failing PCV valve.
