Most of us know the importance of car maintenance. This is especially true for people who have invested in high-performance vehicles, which need to be treated with special care. But what about cars with regular transmissions? You might assume that you should change your exhaust valve as soon as it starts to squeak, or before the oil starts to leak through.
What is an Exhaust Valve and Why is it so Important?
According to the website Exhaust Tips, an exhaust valve is “a valve that opens to allow exhaust gases from a engine to escape.” Its purpose is to ensure that the engine-generated heat is released quickly and efficiently. In other words, it regulates the flow of air and gas through the engine, allowing it to work at its optimum performance.
If your car’s exhaust system is clogged or defective, this can cause problems with your car’s performance and MPG. A clogged or defective exhaust system can also lead to serious health risks if inhaled.
It’s important to regularly check your car’s exhaust system for any signs of trouble and replace any components that need replacing. By doing this, you can keep your car running smoothly and safely and help it achieve its full potential.
How to Handle an Exhaust Valve Replacement
If you’ve ever been on the road and noticed a weird smell, you might have been wondering what’s causing it. That weird odor might be coming from your car’s exhaust system, and it might be time for a valve replacement. Here’s how to handle this repair:
1. Get a copy of your car’s service history. This information will let you know when and where your car’s exhaust valves were last replaced.
2. Call your car’s manufacturer to schedule an appointment for the valve replacement. Your manufacturer may require that you bring your car in for the repair.
3. Contact a local auto mechanic to take care of the repairs on your own car. Make sure to get a quote for the repairs before you decide who to hire.
4. Replace the exhaust valve when it’s due, and keep an eye on your car’s odors to make sure they stay under control.
Venturi Effect
If you have ever changed a car’s exhaust valve, you are familiar with the Venturi effect. This is a phenomenon where the air/fuel mixture in the exhaust pipe whizzes through the valve quickly, and creates a burst of noise. The Venturi effect is most pronounced when the exhaust valve is opened quickly from a closed position.
The Venturi effect has two main causes: bench testing and RPM. When a car is bench tested, the driver blasts the car’s engine with an open exhaust valve to see how much noise it makes. The faster the engine rpm, the more pronounced the Venturi effect will be.
Most experts agree that you should open your car’s exhaust valve slowly so that you don’t experience the Venturi effect. Opening your exhaust valve too quickly can cause too much noise and pollution.
Tips for Shop Success
Assuming you’ve never done this before, it’s definitely a good idea to change your exhaust valve on your motorcycle at least every 10,000 miles. A couple reasons are that, over time, the valve becomes worn and can fail prematurely, and also the intake air can become contaminated with dust and other allergens, which can affect engine performance.
But how quickly should you replace it? That really depends on your particular bike and how often you ride it. If you’re a beginner or occasional rider, go ahead and replace the valve every 10,000 miles. But if you ride more often or your bike is older, go for 15,000 mile intervals instead. And finally, if you have any doubts at all about whether or not it needs to be replaced, just take it in for a tune-up to get an accurate diagnosis.
