Don't Blow a Gasket! (Valve Cover Gasket Replacement)

When you head out to your vehicle after it's been parked and notice oil leaking underneath it, that's something to have looked at right away.  Oil leaks mean your oil level is probably low and running a vehicle in that condition can lead to expensive repairs.

While there are many reasons oil leaks develop, one possibility is a bad valve cover gasket.  Vehicle engines have a cover bolted over the spot where the engine valves are, and that cover keeps the oil inside the engine. In between the cover and the engine is a gasket that keeps that seal tight.  But after many years of high engine temperatures and vibrations, that gasket or the bolts that hold on the valve cover can fail or loosen, and oil can leak.

You may see dirty oil on the valve cover in the engine compartment, near the spark plugs, or around the bolts that hold the valve cover on.  All those are signs of leakage and time to bring your vehicle in for our technicians to check out.

In some vehicles, taking off the valve cover and replacing the gasket is a relatively easy job. In some models, though, other engine parts are located near that part of the engine and must be removed to get at the gasket, so repair costs can vary widely.

The technician will measure to make sure the valve cover isn't warped so it can be reused. If it is warped, they'll recommend replacing it with the gasket.  

While the technician has that area of your engine accessible, they will also check to see if other components need replacing at the same time, which could save you money.  And because valve cover gaskets usually fail in older vehicles, the technician will check for other oil leaks then, too. 

One of the best ways to be sure your valve cover is doing its job is to have your vehicle regularly maintained.  The technician will periodically look over your engine compartment and make sure you know when things are showing signs of age and wear BEFORE they fail and leave you stranded.

A Non-Starter (Alternator Problems in Cold Weather)

As the temperatures dip, we all know there could be problems starting our vehicles. After all, batteries can grow old and not hold a charge as well as when they were newer. Or starters can go bad.  But there's one more component to keep an especially sharp eye on during winter: your alternator.

The alternator is sort of like a small generator. It sends power out to various parts in your vehicle that need electricity.  That includes the battery, which needs charging to keep its power topped off.  The alternator creates electricity by taking mechanical energy from the engine and turning it into electricity.  It is connected to the engine by belts and pulleys. 

In cold weather, the material the belt is made from is less flexible than it is in warm weather.  That means it may not be turning the pulleys as effectively since it doesn't have the same grip. Also, when it's colder, lubricants, including the engine oil, are a little stiffer and parts just don't move like they do when the weather's warmer.  With that extra strain, sometimes it takes the alternator longer to recharge the battery. That, in turn, may leave the battery a little less power to start the engine when it's cold.

You may have a warning light on your instrument panel that looks like a battery.  If it lights up or if you notice your headlights flickering or not shining quite as brightly as they usually do, it could mean a weak alternator. But it also could be an aging battery, corroded battery terminals, a loose belt or another charging system part. Yes, it's complicated. 

Pinpointing the cause involves testing the battery and charging system with diagnostic equipment.  If it does turn out to be an alternator, there are options besides replacing it with a brand new, original equipment part.  Ask your service advisor for recommendations. Obviously, you want your vehicle to start reliably, especially in cold weather.  Take care of your charging system and it will take care of you.

Your Vehicle's Hissy Fit (AC System)

When you hear hissing sounds coming from your vehicle, you might start thinking the worst.   One type of hissing coming from around your air conditioner may be a normal sound, or it could be a sign of serious trouble.

First - the normal sound.  When you turn off your vehicle, the refrigerant goes from its high-pressure side to the low-pressure side. Some of those noises are normal.  But when it hisses all the time, that's another story.

One cause could be that the refrigerant is leaking.  Air conditioners are fairly complex systems that involve various pumps, hoses, valves and motors.  When your air conditioner is cooling, the refrigerant changes from a gas to a liquid and back.  That refrigerant is under pressure, and there are many places it can leak from. 

A hissing sound can also be a failed valve in your air conditioner's compressor.  It is what controls the refrigerant's pressurization.  It's important to have this fixed fairly quickly after it develops a problem because when it isn't, that can lead to more extensive—and expensive—repairs.

If you hear screeching coming from your air conditioner at the same time you hear hissing, your compressor may be on its last legs. It could also be a defective clutch. 

Any time you hear a noise you haven't routinely heard before, bring your vehicle to us so a technician can check the various components and properly repair the problems.  Air conditioning systems are complex and are best handled by a professional with the right tools and equipment.  When your AC has a hissy fit, let us cool it off and you at the same time.

Round and Round (Wheel Balancing)

In a perfect world, all wheels and tires would be perfectly round and weigh exactly the same at every point of the wheel.  Unfortunately, they're not, and if they're out of balance, they can reduce the lifespan of your tires, make your vehicle shake like a carnival ride, and maybe even damage a few suspension parts along the way.  You don't want that!

Wheel balancing, sometimes known as tire balancing, is a process by which a technician makes sure your tire/wheel assembly has evenly distributed weight.  If it isn't, it can give your ride bad vibrations.  If you feel your vehicle's steering wheel shaking, it can mean unbalanced wheels in the front. If you can feel a vibration in your seats, it could be unbalanced rear wheels.

In addition to your vehicle vibrating at higher speeds, there are other signs that your wheels are out of balance. You may see uneven tread wear, or you may notice you aren't getting the kind of fuel economy you used to. 

When you experience these problems, bring your vehicle in, and we can put your wheels on a machine designed to detect any imbalance.  The technician will start your wheels spinning, and a computer will determine how much weight is needed where.  Then, the technician can add small weights on the inside or outside of your wheel rim to precisely balance out the uneven weight.  When the wheel is balanced correctly, it will spin evenly and smoothly.

Sometimes your vehicle will hit a pothole or object in the road that dislodges one of those weights, which can throw that wheel out of balance again.  If so, you'll have to bring it in to have that corrected

Some drivers confuse wheel balancing with wheel alignment. Alignment is making sure the wheels are perpendicular to the road and parallel with each other.  Sometimes your vehicle will need both balancing and alignment done at the same time.

No vibrations are good vibrations when it comes to your wheels.  Bring your vehicle to us, and we'll perform a balancing act to keep your vehicle riding smoothly down the road.

Out with the Old (Vehicle Parts that Wear Out)

Some drivers don't pay any attention to their vehicles until something breaks.  Others take them into their service repair facility for maintenance even before a problem develops.  Still, even if you fit into the second group, there are some parts on a vehicle that will simply wear out over time.

Your vehicle has gaskets in several places.  They use a flexible material to seal the gaps between metal parts that fit together. After time, that material shrinks or gets brittle and fails.  Eventually, after time, you will have to get gaskets replaced.

Same goes for belts.  Your engine has belts that help take the mechanical energy of the engine to drive other parts such as the generator and air conditioner.  Heat and age will eventually cause these belts to wear out or break, so you'll need new ones at some point.

You'll also find yourself buying brake pads.  As much as you may try to go easy on them, brake pads work by wearing off a little bit of them each time they help you stop your vehicle.  Do a lot of stop-and-go driving and you'll hasten the process.

No battery lasts forever, and your vehicle's battery is no exception.  It can only charge and discharge electricity so many times.  Count on getting no more than 4 or 5 years out of a battery, fewer if you live in a very hot spot.

Other parts that don't age well? Tires.  They can have plenty of tread left on them, but rubber gets old and loses its flexibility. Tires have their date of manufacturer stamped on them for a reason.

Finally, your muffler is being subject to moisture from inside and out: inside because of moisture-containing exhaust and outside from the elements outdoors. Stainless steel or other alloys will last longer, but after a while, either the moisture or constant pounding from vibrations will take their toll.

That's why it's important to maintain every part on your vehicle. You can't wave a magic wand and make everything last forever, but take care of your vehicle and it'll take care of you.
