An exhaust valve is one of the most important parts of your car engine. By getting them changed on time, you are likely protecting your vehicle from potential problems and accidents. This article provides a breakdown of how often you should change your exhaust valve based on mileage and year, as well as information about what can happen when it’s left unchanged for too long.
The Function of an Exhaust Valve
An exhaust valve opens when the engine’s air is compressed and sent through the exhaust system. This action removes combustion by-products from the engine, which helps to improve performance and fuel economy. Typical replacement intervals for exhaust valves are every 100,000 miles or every three years.
If you notice unusual smoke or carbon build-up from your exhaust, it may be time to replace your exhaust valve. Transmissions that use manual gearboxes should also be examined for worn gearboxes or clutches about every six months, in addition to the annual tune-up.
How to Replace An Exhaust Valve
If your car’s exhaust keeps emitting a foul odor, it’s time to replace your exhaust valve. A valve punctures the exhaust in the cylinders when the engine is running, and it needs to be replaced about every 50,000 miles or every six years, whichever comes first. For a car with automatic transmission, the valve will need to be replaced every 24,000 miles.
The following guide will help you replace your exhaust valve on a car with an automatic transmission.
To replace an exhaust valve on a car with an automatic transmission:
1 If the car has automatic transmission, remove the cover over the gearshift by pulling it towards you and then gently prying off the retaining clips.
2 On almost all cars there are four bolts that hold down one side of the cover. Use a socket wrench to remove these bolts. Then carefully pull off the cover.
3 Next use a wrench to unfasten the flap covering the seal on top of the engine. Be careful not to damage this seal during removal. The seal should fall free once loosened but can often stick so use some oil or WD-40 if necessary to free it up.
4 Loosen and remove the three bolts

How Often to Replace an Exhaust Valve
The exhaust valve serves as the primary opening for the exhaust gasses from your engine. It should be replaced on a regular basis, usually every 90,000 miles or every three years, whichever comes first. When it starts to show signs of wear, such as reduced performance or poor noise levels, it’s time to take action.
It’s always important to keep your car engine running as clean and efficient as possible, but it can be tough to determine when it’s time for an exhaust valve replacement.
