Exhaust Valve Replacement – 5 Things You Need To Know

If you own a car or truck, it’s likely that your exhaust system is made up of various parts. These parts include the exhaust valve, which helps expel harmful gases and fumes from your engine. If this part fails, it can lead to a number of problems. In this blog post, we will provide you with 5 things you need to know about exhaust valve replacement. From cost to what to expect during the repair process, read on to learn all you need to know.

What is an Exhaust Valve Replacement?

An exhaust valve replacement is a procedure that restores the function of an old, malfunctioning exhaust valve by replacing it with a new one. This surgery can be necessary on some vehicles if the old valve begins to leak air and/or oil, making it difficult to accelerate or drive. In most cases, this surgery can be done without having to remove the entire exhaust system.

Types of Exhaust Valves

There are a few types of exhaust valves, each with its own specific benefits and drawbacks. Here’s a look at the three most common types:

  1. The Butterfly Valve: This type of valve is often used on motorcycles because it offers good air flow and low noise levels. However, the butterfly valve can be difficult to replace, requiring special tools and experience.
  2. The Rocker Arm Valve: This type of valve is more commonly found on cars and trucks because it allows for more precise control over air flow. It also has a lower noise level than the butterfly valve, but replacement can be more difficult due to the location of the valve assembly.
  3. The Dual-Exhaust System: Many cars now come equipped with dual exhaust systems, which offer better performance and lower emissions levels. To replace an exhaust valve on a dual-exhaust system, you will first have to remove both the stock mufflers and catalytic converters.

How Does an Exhaust Valve Work?

An exhaust valve is a component of an engine that helps to control the amount of air and gas that is released into the atmosphere. When the engine is running, the exhaust valve opens and allows air and gas to escape. This helps to reduce fuel consumption and emissions.

Symptoms of an Exhaust Valve Replacement

If your car’s exhaust valve is making a knocking noise, it may need to be replaced. The valve can become damaged over time, which will cause the noise. In some cases, the knocking noise may also be accompanied by poor engine performance. If you think your exhaust valve is causing problems, schedule an appointment with your mechanic to have it replaced. Here are some things you should know about exhaust valve replacement:

1. What Does an Exhaust Valve Do?

An exhaust valve opens and closes as the car’s engine gasps and spits out fumes. The sound of the knocking is caused by the valves hitting each other repeatedly as they open and close. Over time, the valve can become damaged and cause the noise and performance issues described earlier. Typically, an exhaust valve will need to be replaced if it makes a loud knocking noise or if the car has difficulty passing emissions tests.

When To Replace Your Exhaust Valve

Your car’s exhaust valve is a vital part of the emissions-control system. It helps your engine expel pollutants from the exhaust pipe. Over time, the valve can become worn or defective, which can cause your car to emit an unhealthy amount of pollutants. If you notice that your car’s exhaust fumes are becoming especially strong, or if you experience any unusual noises from your vehicle, it’s likely that you need to replace your exhaust valve. Here are some things to keep in mind when replacing your valve:

  1. Make sure that your car has the proper tools and parts necessary for the job. Your local mechanic may have all of the required tools and parts on hand, or you may need to order them online.
  2. Disconnect the negative battery cable before beginning work on your car. This will prevent any accidental start-ups while you’re working on it.
  3. Remove the cover plate over the engine intake manifold using a socket wrench or a hex key (if applicable). Be careful not to damage any pipes or hoses connected to the manifold while removing this plate.
  4. Remove the exhaust pipe by unscrewing it from its bracket on either side of the engine bay (see image below). Make sure to label each bolt and nut so that you can reattach them in reverse order when you install the new valve:
  5. Clean all of the surfaces surrounding the new valve with a solvent such as acetone or methylene chloride.
  6. Insert the new valve into the exhaust pipe, aligning the tabs on the valve with the slots in the pipe. Fit the nut and bolt on each side of the valve into their corresponding holes in the pipe and bracket, and tighten the bolts using a wrench (see image below). Once tightened, use a Phillips head screwdriver to rotate the valve until it’s properly seated in its housing (see image below).
  7. Replace the intake manifold cover plate and reattach the negative battery cable before driving your car.

Costs of an Exhaust Valve Replacement

Exhaust valves are small metal pieces that sit on either side of the exhaust pipe and allow hot air and exhaust to escape from your engine. Over time, exhaust valves can start to become corroded or worn, which can cause them to leak or simply not work as well as they should. When this happens, your car may start to smoke and feel rough when you drive it. In extreme cases, an exhaust valve replacement can fix all of these problems. Here are some things you need to know before getting your valve replaced:

The cost of an exhaust valve replacement varies depending on the type of valve and the severity of the issue. Expect to pay around $200-$600 for a standard replacement, though prices can be higher if the valve is defective or has been damaged in some way. Parts and labour costs will also vary depending on where you live, so it’s important to speak with a trusted mechanic about your specific situation before making any decisions.
