How do you know when your exhaust manifold is bad?

### Signs of a Bad Exhaust Manifold.

Experiencing issues with your exhaust manifold can lead to a variety of problems with your vehicle. Knowing when your exhaust manifold is bad is important in order to prevent further damage to your car. Here are a few signs that may indicate a bad exhaust manifold:

#### Step 1: Listen for Noise .

One of the most common signs of a bad exhaust manifold is a loud noise coming from your engine. A leaking exhaust manifold can cause a noticeable hissing or tapping sound, especially while the engine is running. This noise is often the result of exhaust gases escaping from the cracked or damaged manifold.

#### Step 2: Check for Decreased Performance.

Another indicator of a faulty exhaust manifold is a decrease in engine performance. If you notice a loss of power, reduced fuel efficiency, or difficulty accelerating, it could be a sign that the exhaust manifold is not functioning properly. This drop in performance is often due to the disruption in the exhaust flow caused by a damaged manifold.

#### Step 3: Look for Leaks .

Inspecting your exhaust manifold for leaks is another way to determine if it is bad. Visible signs of leaking, such as black soot around the manifold or the smell of exhaust fumes inside the car, can indicate that there is a crack or hole in the manifold. Additionally, you may notice a burning smell while driving, which can be a result of exhaust gases leaking from the damaged manifold.

#### Step 4: Feel for Vibrations .

If you feel excessive vibrations while driving, it may be a sign that your exhaust manifold is bad. Vibrations can occur when the manifold is cracked or damaged, causing the exhaust gases to escape unevenly and create an imbalance in the engine. These vibrations can be felt throughout the vehicle, especially in the steering wheel or pedals.

By paying attention to these signs and symptoms, you can determine if your exhaust manifold is bad and in need of repair. Addressing any issues with the exhaust manifold promptly can help prevent further damage to your vehicle's engine and ensure that it continues to run smoothly.
