Four Things You Didn’t Know About The Exhaust Valves On Your Car

Car exhaust valves are one of the most often overlooked components on your vehicle. It’s not until something much worse than a little smoke from a tailpipe pops up that you really think about them. Read this blog post to learn about the top 4 things you’re doing wrong with your valves.

Evaluating Your Car’s Condition

1. Four out of five exhaust valves are located on the engine side of the car. 

2. The fifth valve is usually a noise suppressor, but it can also be opened in an emergency to allow more air into the engine. 

3. When the car is cold, the exhaust valves can stick shut and cause an exhaust odor. 

4. The rubber gasket that seals the exhaust valve to the exhaust pipe can deteriorate over time, which can lead to excessive noise and a loss of horsepower.

How Do Exhaust Valves Work?

The exhaust valve on your car opens and closes as the engine kicks in and out of gear, allowing combustion gasses to escape. Expired air is also expelled through these vents. If the valves don’t work properly, the air can’t escape and the car will start to smell bad.

What Can Go Wrong With Your Car’s Exhaust Valves?

There are four things you didn’t know about the exhaust valves on your car. 

The first is that they can be a source of trouble. If they’re not working properly, they can cause your car to run poorly and emit an unpleasant smell. In extreme cases, they can even cause your car to blow up. 

The second thing you need to know is that they can also be a source of noise. If they’re not sealing properly, they’ll make a lot of noise when your car speeds up or brakes. This noise can be particularly bothersome if it’s constant and loud. 

The third thing you need to know is that the valves can fail prematurely. If the oil inside them gets dirty or contaminated, it can cause the valves to fail. This can lead to a lot of noise and smoke coming from your car, as well as problems with acceleration and braking. 

Finally, the fourth thing you need to know is that sometimes the valves themselves can become defective. If this happens, you’ll need to replace them in order for your car to function correctly again.

Things To Keep In Mind When Buying A New Car

If you’re thinking of buying a new car, make sure to check the exhaust valves on your vehicle. These valves regulate the flow of exhaust from the engine and can cause problems if they’re not properly replaced or maintained. Here are four things you didn’t know about these valves:

1. They can fail prematurely – One common problem with exhaust valves is that they can fail prematurely. This can lead to a build-up of heat and pressure in the valve, which can eventually cause it to rupture. In some cases, this rupture may not be noticed until the valve becomes loose and starts making strange noises. If you suspect that your valve is failing, be sure to have it inspected by a mechanic.

2. Replacement is necessary – If your valve does fail, it will need to be replaced as soon as possible. Depending on the severity of the failure, replacing the valve may be as simple as unscrewing it from its housing and replacing it with a new one. In some cases, however, the valve may need to be completely overhauled in order to restore proper function.

3. Maintenance is key – Keeping your exhaust valves properly maintained is essential for their longevity. routine checks by a mechanic should include inspecting


If you’re like most drivers, your exhaust valves are one of those parts of your car that you take for granted. But if they go bad—or even just stop working correctly—they can lead to ridiculously expensive repair bills and long delays in getting back on the road. In this article, we’ll tell you four things you didn’t know about exhaust valves (and why they’re important). Hopefully, this will help you stay safe and informed when it comes time to service yours.
