You've probably heard of the exhaust manifold before, but that doesn't necessarily mean you're clear on what it does. In fact this system is very important in the operation of your vehicle. It connects the cylinder head to your engine's exhaust port. This makes it possible for the hot exhaust to travel through a pipe instead of seeping out into the air and the vehicle itself. The manifold can be made of cast iron or a set of pipes, it all depends on the vehicle you are driving.

Because this manifold is always cooling down and heating up as the gasses pass through it, it means the pipe is contracting and expanding regularly. This can be quite hard on it, and even result in cracks and breaks. Once this happens, the fumes will begin to leak. These leaks are very dangerous to your health since you'll be breathing in the gasses instead. As well it starts to decrease the performance of your engine.

With the exhaust manifold it isn't a question of whether or not it will fail over time rather it is a question of when it will fail. It's a good idea to have your exhaust manifold inspected by a certified mechanic from time to time, just so you can get an early jump on any cracks. In the meantime, here are some signs you can watch for that may indicate your exhaust manifold is in need of replacement.

  • Because your engine won't be running efficiently, your Check Engine Light will likely come on. You'll need a mechanic to read and then clear the computer codes.

  • Your engine may not work as well as it used to, as a failed exhaust manifold impacts engine performance in a big way.

  • There are sounds and smells that can also act as tip-offs. The engine can begin to make loud noises that you'll be able to hear, even while driving. If the exhaust manifold is leaking, then you'll likely be able to smell odor coming from the engine compartment. It will be the smell of the plastic parts that are located beside the exhaust manifold, which are now melting thanks to the heat that is leaking out.

The exhaust manifold connects the cylinder head to the engine’s exhaust port. Once this part fails, you will notice all kinds of things start to happen with your engine and overall vehicle performance. If you’re experiencing any of the above mentioned symptoms and suspect your exhaust manifold is in need of replacement, get a diagnostic or book an exhaust manifold replacement service with a professional mechanic.

James was great. Some rust issues slowed down the job and made things a little more expensive. As soon as he knew there was an issue, James made sure I was aware of the problem and was OK with the added time and expense before he continued. He managed to replace my exhaust manifold in half the cost and half the time the dealership quoted me, gave me twice as much detail as the dealership would have ever given me, and was much friendlier and more respectful than any mechanic I've dealt with in the past.

Finding Your Mechanic and especially Brian was exactly what I needed. Brian is very friendly and knowledgeable. With my busy schedule, this service is super convenient with Sunday hours. I just don't have time to spend in a shop or dealership. Brian's work is top notch and less expensive than taking my car to a dealership.
Saturn Aura - Exhaust Manifold - Keymar, Maryland
I had a great experience. The mechanic was early. He went right to work. When finished, he showed me the damaged parts, explained what was done, and answered all of my questions. He even gave me a reference to another mechanic that does welding that he doesn't do. Price was great and I wasn't charged until the work was complete

Once we worked out the scheduling issues, he asked if it was okay to arrive early. I was all for that. He finished the job in the exact amount of time the website said it would take. Very personable and does good work. I would definitely use Lee again.
