A car can produce so many niggling little noises and it’s best to get them dealt with as soon as possible. No one likes a car with too many splutters and spurts, though an amount of revving does sound attractive to the car buff.
If a car is running too loud this may be caused by a dirty sensor. The sensor causes too much or too little fuel to enter the engine, which makes it seem to the driver as though it’s running rough. Faulty spark plugs in contrast will cause it to backfire.
A knocking, or grinding noise is likely coming from a bad engine bearing – these are what the engine is sat on. Driving long distances will really bring out this noise. The bearings might not be shot entirely, if could be low oil pressure that indicates inadequate lubrication. Either way—it’s recommended that you deal with this as soon as possible.
Transmissions can be a source of noise. Having a low transmission fluid levels can damage the torque converter. If the transmission is failing see a mechanic straightaway.
If your vehicle sounds louder than it used to, another reason could be a damaged muffler. In this case you would hear the engine because it’s not being masked by the muffler. Usually one of your neighbors will clue you into this problem if you haven’t noticed yourself.
New plans to fine people whose exhausts are too loud involve using a noise camera. A noise camera might be better explained as a traffic camera with an audio sensor attached. Much like a motion detector camera, the noise camera will trigger when it detects a loud car and snap a picture of the cars number plate. A trial of this system in Edmonton, Canada just made people rev their engine around the camera producing inaccurate results.
Noise pollution makes lives a misery, and it’s not just uptight killjoys who have a problem with it. Too much noise can cause high blood pressure, stress eating and even type 2 diabetes. But the issue could be just too many vehicles in one location. If it’s the total number of cars, motorbikes and trucks you can still try to fine the worst offenders, but that means on the ground tickets by police. In reality, cars make more noise when starting up than running, and a little extra noise for a short time is considered acceptable. So, police would need to ticket only those who’s vehicles “run” loud, not just because they’re capable of being loud at times. No one likes an on-the-spot fine but it’s the only solution.
Other Possible Solutions
If engine noise is a problem a flame retardant pad under your hood can suppress it. It’s important to replace the item after a few years as when it becomes worn out it becomes useless. You can probably tell when it’s worn out as the sound will gradually come back.
Of course, the main reason cars are loud is because their owners deliberately changed the muffler. It’s not just police you get into hot water with when you replace your stock muffler to make your car sound more muscular. Like with your insurance company for instance. Most policies say that you shouldn’t alter your vehicle without letting them know. “Souping up” your exhaust counts as an alteration even though it doesn’t change your horsepower.
It’s increases the appeal to thieves. It’s more likely to be stolen and you’re more likely to want that feature in your replacement vehicle they buy you. So, it increases their liability and they’ll increase your rates. Not telling your insurer may make your policy invalidated.
One Final Note:
Technically when you modify a car it violates the warranty and wrecks the value, however if you do a good job it can make your car more desirable to people with the same taste—so it sells faster. Some exhaust replacement does improve performance. But think before you spend the money.
On that note, think before you make a ton of noise. Some noise is good, but go overboard and you’ll get a ticket.
