What are some of the most common signs of a valve being bent? No, they wouldn’t stop the engine. Well, if the valves are bent, the engine can be completely destroyed. When one or more valves are bent, you should immediately stop driving and contact a mechanic.
A “very” noisy engine is one of the most prevalent signs of bent valves. It’s possible that you’ll hear a loud noise as you drive because of the bent valve, which prevents emissions from escaping and also inhibits air from entering the engine cylinders. A wide range of unique symptoms and indicators can be caused by a valve that has been bent. We’ve included the most prevalent indicators of bent valves, as well as what you should do if you find yourself in this position.
Common Symptoms of Bent Valves
Your engine’s valve may bend for a variety of reasons, but the most common are a damaged timing belt and overheating. In the event that one of your valves fails while driving, you’ll immediately notice any of the following symptoms.
1. Instant Power Loss
A reduction of power would be immediately noticeable if the valve went bad while you were driving. Your engine’s performance would plummet to the point that it appeared to be unable to start any longer. The loss of power is caused by inefficient combustion in the engine’s chamber due to a faulty valve.
2. Loud Engine Noise
Driving with a bent valve, it turns out, makes a strange, loud noise as you try to accelerate. Because the bent valve prevents air from escaping from the cylinder, the noise is louder than it would otherwise be. As soon as you hear this type of noise, check your engine valves first.
3. Increase in Oil Usage
Another indicator of a bent valve is if your car suddenly uses more oil than usual. Bad valves impair the engine’s performance, making it use more oil while not improving its performance.
4. Check Engine Light Is On
The check engine light will come on if you have a problem with your car’s engine. The light comes on to alert you of a problem with your engine that the car’s computer has detected (the engine). It is vital to note that the Check Engine light might be triggered by bent valves, despite the fact that there are many other possible causes.
When your valves bend, you may experience “engine shaking.” Due to bent valves, your automobile will tremble while in motion, and may potentially misfire. So, if you’re experiencing any of these unusual symptoms, it’s time to get your valves checked out and possibly replaced.
6. Car Won’t Start
All vehicles have a certain amount, but how many valves they have is determined by their engine size and how many cylinders it has. You may still be able to drive the automobile if only one or two valves are bent, but you’ll notice a lot of irregularities. However, if there are more bad/bent valves than healthy ones, then the automobile is likely to not start. You should avoid starting the automobile if it reaches this point, otherwise you risk damaging your engine.
Vehicles of any make or model might display these typical signs of a faulty valve (once the valves are no longer in good shape). Aside from that, some mechanics claim that faulty valves might produce low-cylinder pressure. It’s not uncommon for engines to lose power, and in the worst-case scenario, a cat won’t start at all, due to bent valves.
