TCB your PCV (PCV Valve Replacement)

Your gasoline engine goes through some exhausting work.  Yes, it's truly exhausting, as in: it produces exhaust! And when your engine starts behaving like it's exhausted, such as running poorly or getting lousy fuel economy, the trouble may be something called a PCV valve.

Did you know it's a series of explosions that creates the power in your engine? The spark plugs ignite a mixture of gasoline and air and BANG! A whole bunch of those and you're engine is humming away. Leftover vapors from those explosions go into your crankcase, which is also a place where engine oil goes.  Those vapors still have a lot of unburned fuel in them, and if they had nowhere to go, they'd turn your oil into a thick mess called sludge, not good for a smooth running engine. 

Engineers came up with an idea. Re-direct those gasses building up in the crankcase into the engine's air intake and mix them with fresh air.  That way the unburned fuel could go through the engine again and produce power. It also means the unburned fuel doesn't pollute the air.  The part that makes that happen is called the Positive Crankcase Ventilation (PCV) valve.

Besides reducing pollution and preventing the oil from turning to sludge, the PCV valve also relieves pressure in the crankcase, reducing the potential for oil to leak. One of the reasons you should get your oil changed as frequently as your vehicle's manufacturer recommends is that it helps reduce chances for problems with the PCV valve.

After a while, the PCV valve can itself get gummed up and stick, and the driver may notice oil leaks, reduced power or engine hesitation.  That's why it's important to make sure the PCV valve is operating like it should, and often it can be diagnosed during a visual inspection by our technicians.  Replacing a PCV valve is usually quick and inexpensive.  After it's done, your vehicle will run with the performance and fuel economy you're used to.  Goodbye exhaustion!

Road Ready (Trip Inspection)

Maybe you've been cooped up for a while and are yearning for a change of scenery.  Or maybe you need to visit a relative who lives far away.  You choose not to fork out the big bucks for airline tickets, so it's time for a road trip.  Make sure you're road ready by having your vehicle professionally inspected before the big drive.

One of our technicians can check out several of your vehicle's most important systems so you can be more confident that you'll be able to go the distance without a breakdown.  Here are a few things a trip inspection may include:

Your vehicle stops with brakes that, in turn, stop the tires.  They must both be in sound condition. The technician can look at your tire tread, the condition of the sidewalls, and note the tires' age.  Brakes have pads and rotors that should meet certain specs, so an expert inspection of their condition is important, too.

A technician can check other vital fluids such as engine coolant, power steering, transmission, and windshield washer fluid. Your wipers must be in good condition so you can see, and they're often one of the most neglected parts of a vehicle. 

Your headlights must work correctly and be aimed properly so you can see and so that you're not blinding oncoming drivers. They're powered by your battery, and a technician will check how old yours is and how well it holds a charge, all important for reliable starting. 

For cabin comfort, your climate control system needs to work correctly, which means both heat and air conditioning.  If things need to be repaired - before the trip will be a lot more convenient than trying to do it while you're traveling.

The technician can inspect hoses and belts, two things that frequently fail on a long trip.  And the big advantage of having a pro look over your vehicle is that they not only know what to look for but also can make the repairs the right way.  Now that's the ticket to being road ready.

To Fix or Not To Fix (Tire Repair)

You know that sinking feeling when you realize one of your tires has a problem.  It may be making an odd noise or behaving oddly when you're driving.  You may hit a pothole or curb and one suddenly goes flat.  Or you may head back to your vehicle and discover it has one tire deflated without a clue of what must have happened to it.

With a lot of different tires hitting the streets these days, the issue of whether to have a tire repaired or replaced can be tricky, and we strongly recommend you have a trained technician help you make that decision. 

One of the most common causes of flat tires is picking up a screw or nail in the tread area.  Many of those can be patched and plugged if the puncture isn't more than ¼ inch/6 mm in diameter. Most tires can handle two of this type of repair, but any more and you should buy a new tire. 

If there's a puncture or bulge in the sidewall or shoulder, the rule of thumb is it's not repairable.  The sidewall doesn't have the reinforcements that the tread area does.  In fact, any puncture that's more than a ½ inch/12 mm away from the edge of the tread should not be fixed. 

Many newer vehicles have no spare tires (to save weight and fuel) and instead have a type of tire called "run-flat."  Sometimes, the only way you know they're deflated is when the tire pressure monitor alerts the driver.  Driving on them more than 50 miles/80km can render them un-repairable.  They may be fixable if you pulled off to the side of the road before driving on them too long. Our technicians can evaluate whether they can be driven further or should be replaced.

Other vehicles with no spare include a can of tire sealant and a compressor.  If you use it, tire experts say to have the tire professionally repaired as soon as possible.

If you have had a flat tire, try not to drive on it unless it's necessary to get your vehicle away from a dangerous situation.  Our technicians can evaluate any tire you may be having problems with and recommend whether repair or replacement is the best option. Your safety is riding on your tires.

All Lined Up (Alignment Inspection)

When you head down a straight road, does your vehicle pull to one side?  Do you feel vibration in any of the wheels? If you've noticed any of these things, it's probably time for you to get your wheel alignment checked.

When your vehicle left the factory, its wheels were parallel to each other and perpendicular to the ground.  That maximizes traction for good steering and braking. Every time you take your vehicle on the road, normal wear and tear will affect your alignment. Hit a bump, a pothole or a curb and all those little knocks will add up

Bad alignment not only can cause your steering wheel to pull unevenly, it can also wear your tires out a lot faster than they should. In fact, if you look at your tires and see one side of the tread is a lot smoother than the other, it could be another sign of bad alignment.

Since different problems can cause similar symptoms, the first thing our trained technician will do is test drive your vehicle. Then, they'll check the front end and steering linkage as well as look for tire wear.  Then, the technician will put your vehicle on a lift and use computerized diagnostic equipment to measure alignment angles so they can precisely align your vehicle's components.

There are different kinds of alignments.  One is a front-end alignment that aligns components of the vehicle's front axle.  Another is a thrust alignment that makes sure the front wheels are lined up with the direction the rear wheels are pointed.  A third type is four-wheel alignment which is usually used on all-wheel drive and  4-wheel drive vehicles.  It's also recommended for front-wheel drive vehicles that have independent rear suspensions.  It makes sure the angles of all the wheels are where they should be relative to each other and also the vehicle's body or frame.

Your steering wheel should be perfectly centered if you are heading straight down the road, so the technician will adjust it so it is. Finally, they'll take your vehicle back on the road for a final test drive to make sure it's performing the way engineers intended.

Your service adviser can recommend how often you should have your alignment inspection, since it depends on the type of vehicle you drive (SUV, sporty car, etc.) and your driving environment.  Properly aligned wheels can help your vehicle perform better and save you from expensive repairs down the road.

Heat and your Tires (Tire Pressure Monitoring System)

With hotter weather and brutal heat waves becoming more common, the pressure in your vehicle's tires goes up.  After all, heat causes air to expand, and the air in your tires follows the laws of physics. Overinflated tires can reduce your vehicle's traction, cause a hard, punishing ride and make your tires wear out faster; all are important safety issues.

Four out of every ten drivers rarely check tire pressure. Some rely on their vehicle's tire pressure monitoring system (TPMS) to keep an eye on proper tire inflation.  But it's not designed to do that.

TPMS is a safety feature that has been required on vehicles made in 2008 or later, using sensors in the wheels that alert you to tire pressure problems.  That warning can be a light on your dash, a digital message or a readout of the pressure in each individual wheel.  But a study showed that more than 40 percent of drivers don't even know what the tire pressure monitoring light symbol looks like!

One looks like a horseshoe with an exclamation point in the middle.  The other looks like an overhead view of your vehicle with the tires at all four corners.  They may even show the inflation number (usually in pounds per square inch, or PSI).

The TPMS is designed to alert you that your tires aren't inflated within certain parameters, but the system shouldn't be a substitute for frequently having your tires checked with a tire gauge.  A TPMS light is only required to come on when a tire is 25 percent under the recommended tire pressure; by that time, you're driving on an unsafe tire and causing excessive wear.

Have your vehicle checked regularly by our professionals, and that includes tire pressure checks.  If you do see the tire pressure warning come on, have our service center look at it soon.  You may have a tire with a problem or the TPMS system may not be working right. 

Either way, since your tires are the only contact your vehicle has with the road, your safety depends a great deal on your tires being in top shape and correctly inflated.  Keep your tires properly inflated and your TPMS working to alert you of any problems. And that's not just a lot of hot air.
