Bad exhaust system is a drag for car owner and their Johnsburg neighbors

You're probably not the only one to notice

that you have a problem with your car's
exhaust system; your Johnsburg neighbors
know, too.

When Mary left her Johnsburg driveway, her mind was on the chores she had to run. But she wasn’t driving more than a minute when something else caught her attention. The car was much louder than usual.

Maybe she didn’t entirely notice the difference at first, since she usually turned on the radio for her favorite music before she took to the Johnsburg road. But, even then, she noticed something and turned the radio down.

There was no doubt about it; the car was much louder than usual. But more than a louder engine sound, she’s liable to hear a loud scraping sound. She’s probably wondering, ‘What the heck is going on?’

What’s going on is that her exhaust system has a problem. The loud sound of the engine is because a hole has appeared in the exhaust and/or the muffler has failed. It’s no longer doing its job and anyone who hears the car go by knows why. They can’t help but hear it.

If she also has a loud scraping sound accompanying the louder engine sound, that means a portion of the exhaust system has broken off and is dragging on the ground.

From outside the car, a dragging exhaust pipe or muffler is something you hear. From outside the car, watching it go by, it’s liable to include a visual show, too; others are liable to see a shower of sparks flying back from the offending part of the exhaust system.

Both of these problems are to be avoided.

Illinois Sec. 12-602. Mufflers, prevention of noise requires that “… at all times (vehicles) be equipped with an adequate muffler or exhaust system in constant operation and properly maintained to prevent any excessive or unusual noise.”

In other words, you can get a ticket, with a fine of $75 to $125, for driving around with a defective exhaust system. But the trouble could go deeper than simply a matter of noise.

You’ve probably noticed that most automobile exhaust systems extend to the very back end of the car. This is because you don’t want those exhaust fumes drifting up into the cabin of the car. For the same reason you don’t want to run the car in the garage with the door closed, you don’t want exhaust fumes joining you inside the car.

As for that shower of sparks, it may look interesting to onlookers, you probably don’t want sparks showering your vehicle’s gasoline tank.

Another thing to consider is that your car’s exhaust system is designed to provide a certain amount of backpressure on the engine. The engine was engineered to run that way. If the exhaust system is defective, the backpressure is changed and it will effect the performance of the engine.

Finally, if you’re exhaust system is defective, you’re liable to annoy your Johnsburg neighbors. These are all good reasons to maintain your car’s exhaust system in optimal condition.

Is your antifreeze safe from freezing this Richmond winter

You still have time to have it checked Well, there’s no denying it – winter tends to get chilly here in Richmond. We have to deal with snow and ice on the roads, scraping the same off our windows and windshield, and staying warm while we drive. Of course, you had your antifreeze checked before winter rolled into town. What?! You didn’t have your antifreeze checked before winter clamped down on Richmond? So, how’s your antifreeze doing? If you haven’t had it checked, there’s really no way of knowing, is there? This car has overheated in the middle of a Richmond winter. But, on the other end of the spectrum, the antifreeze can also freeze if it's not up to its job. Hopefully, you haven’t had a serious problem with your antifreeze already. If you did, you’d probably know. When antifreeze fails, it’s a potentially catastrophic condition for your vehicle’s engine. You could have hoses that have burst because of freezing antifreeze. Worse than that, your engine block may have crac...

Blocks of ice falling from cars in McHenry could cause accidents or damage

We’ve all seen those blocks of snow falling from behind the rear tires of a car when the snow rolls into McHenry . Fortunately, they’re just packed snow that will disintegrate under your vehicle’s tires as you simply drive right through them, right? Don’t count on it. Those blocks of snow are often packed so tight, condensed by the thaw-and-freeze cycle, that they’re anything but oversized snowballs . They’re often more like boulders. Hit one of those blocks and the collision between the block and one of your tires could send you careening off the road or into oncoming traffic. In some cases, they’re so solid you could pound them with a sledgehammer with little effect. They truly can represent a serious road hazard. The problem is that it’s difficult to tell how solidly they’re packed when you see them on the road, left their unwittingly by another driver. Either way, your best bet is to try to avoid them. But you want to be careful dodging blocks of ice in the road, too. You need...

Get out to McHenry Music Festival for a good time and music near to home

Some folks here in McHenry will load up the car and head out to Red Rock Amphitheater near Denver to see a show. Some will go to the MSG Sphere near Las Vegas. Some will go to the Bonaroo Festival Concert to see a show. That’s quite a bit of driving and you’d better make sure your vehicle is up to the trip. What happens, however, if something goes wrong – if your vehicle breaks down while driving there or back? What happens if the show is canceled, as happened this year with the Bonaroo Festival? We’re talking about some serious inconvenience, aren’t we? Wherever you go, whether your driving to Colorado, Nevada, Tennessee or anywhere else in this continent, you want to perform your due diligence and make sure the vehicle is up for the trip before you go. And it doesn’t really matter if you’re driving somewhere to see some live music or for any other purpose. A breakdown can be costly and may put you at the mercy of weather conditions or nefarious characters that come across you while y...
