The Little Valve that Could (PCV Valve Replacement)Posted October 30, 2022 8:28 AM
It's easy to get letters like PVC and PCV mixed up. PVC is a plastic that's used in a lot of things, especially plumbing pipes. And PCV is a valve that helps your engine burn off excess fumes rather than having them pollute our atmosphere.
PCV stands for positive crankcase ventilation. When your engine ignites gasoline in the cylinders, some of the gases produced make their way into the crankcase, where oil is held to lubricate the engine. In earlier days, those gases would be vented out through a hose and go directly into the air. It was a waste of gasoline (since about three-fourths of the gases were unburned fuel) and a nasty source of pollution.
So engineers devised a one-way valve that directed those gases back into the engine's air intake system to be burned again. After a while, the PCV valve can get clogged up with gummy oil. Not only does that reduce the recirculation of the gases, but it can also cause pressure in the crankcase to increase and possibly lead to an oil leak.
Signs your PCV valve has failed are oil leaks around the engine compartment or under your vehicle and poor engine performance. Your fuel economy will get worse. If you notice those signs, we can check your PCV valve.
At the same time a technician inspects the PCV valve, they'll also check the vacuum hose that runs back to the air intake. Plus, they'll make sure the vehicle doesn't have any other engine problems that might be contributing to your issues.
Many technicians recommend replacing your PCV valve with each major tune-up, so you get ahead of any problems before they develop. Now that you're an expert on PCV, it may be time to check out those PVC pipes in your bathroom!
When Are Your Tires Worn Out?Posted October 23, 2022 8:13 AM
Hey Memphis area drivers, are your tires worn out? What is the standard for our TN streets? How can you tell on your vehicle?
So what happened with the 2/32 inch/1.6 mm tires on the car? Get this – when the car had traveled the distance required to stop with new tires, it was still going 55 mph/89 kph. Stopping distance was nearly doubled to 379 feet/116 meters, and it took 5.9 seconds.
Trip Inspection at Madison Automotive in MemphisPosted October 16, 2022 7:30 AM
Memphis area drivers love their vehicles. And one of the most enjoyable things about them is taking a road trip. Freedom from daily schedules, new sights and the open road – it's great! But there's nothing like vehicle trouble to bring the fun to a grinding halt.
Prepared with answers to these questions, you can schedule a trip inspection at Madison Automotive in Memphis to help you prepare your vehicle for your big adventure. A lot of our Memphis customers prefer to go through this exercise with their friendly and knowledgeable service advisor to get their input and make sure they haven't overlooked anything.
Shocks and struts play a major role in both driving comfort and safety. If they need to be replaced, you'll really be glad you did once you hit the road. Is it time for a wheel alignment? Fighting a car that's pulling to one side all day can be tiring and dangerous.
And don't forget your brakes. Any strange noises, grabbing, soft or hard peddle feel? If there is any doubt, get a brake inspection at Madison Automotive in Memphis before you leave.
Moving under the hood, have a belts and hoses inspection. If something is excessively worn or near failure, the stress of a long road trip might just be the straw that breaks the camel's back. Talk to your service advisor at Madison Automotive.
Do you notice any unusual odors in your vehicle? If so, it could be as harmless as a dirty cabin air filter. But if it's an exhaust leak, it could be fatal for Memphis drivers and their passengers on a long trip. Of course you'll want to be comfortable, so get an air conditioning service if you aren't getting the cold air you’re used to.
Are your wiper blades still working well? If not, that is a quick and inexpensive fix for Memphis drivers. Headlamps are often overlooked when planning for a trip. If you haven't changed the bulb in six months or so, replacement bulbs will really light up the night on your trip and provide the necessary after-sundown visibility.
All the items mentioned are part of any good vehicle maintenance plan. These are things that you want to take care of anyway, but they all become more important as you plan for your trip.
Ethics of Automotive Repair in MemphisPosted October 9, 2022 8:20 AM
For example, it you take your car in for a grinding noise when you step on the brakes, you may just think you need new brake pads. After the inspection, the technician at Madison Automotive says that you have a cracked rotor and need to replace it.
Of course, the technician has the burden of making ethical recommendations and properly educating their customers. For the customer, if you are uncomfortable with a recommendation, ask some questions. More information is always a good thing.
Automotive Tips from Madison Automotive: Causes of Wheel MisalignmentPosted October 2, 2022 10:55 AM
When properly aligned, all of your wheels are pointed in the same direction. Your vehicle will track true and handle the way it is designed. Memphis drivers often associate our wheels being “knocked” out of alignment with an event like a major crash, hitting a pothole, curb or some other object. While these can certainly take your wheels out of alignment, the bumps and bounces of everyday Memphis driving take their toll on wheel alignment as well. Your car can lose alignment over time with just normal driving.
When your wheels are out of alignment, the team of automotive professionals at Madison Automotive in Memphis can return your wheels to the factory settings. Most owners’ manuals suggest an inspection every year or two.
