PCV Valve: What Is It?

Most Garner drivers know something about preventive maintenance on a vehicle. We know we should routinely replace the oil and wiper blades and other fluids. But have you heard of a PCV valve ? This little car part needs to be replaced regularly or it can cause some serious problems in your vehicle engine.

PCV stands for Positive Crankcase Ventilation. The crankcase holds your motor oil and is located at the bottom of your engine.

When fuel is burned in your engine, it produces waste gases that are mostly vented out through your exhaust system. But some of these gases push their way past the pistons and into the crankcase. There, these gases can mix with motor oil to produce oil sludge, which can damage vehicle engine parts through corrosion and by clogging engine passages. Garner vehicle owners should be advised that if the engine is running at high speeds, these gases can also cause pressure inside the crankcase to build up. This pressure, in turn, can blow gaskets and damage seals, leading to oil leaks.

The waste gases that leave the engine are comprised of about 70% unburned fuel. They used to be vented off the crankcase into the atmosphere. But starting in 1964, laws mandated that these gases be recaptured. Manufacturers began installing PCV systems, which recycled the gases into the air intake system where they could be mixed with fuel and sent to the engine to be burned.

The PCV valve is a one-way valve attached to the crankcase. Waste gases exit the crankcase through the valve but cannot enter.

Over time, the waste gases leave deposits on the PCV valve that can gum it up. So it needs to be replaced occasionally. This is an inexpensive part of preventive maintenance that is often overlooked, but which can have very expensive consequences. It's good auto advice to keep this little valve clean and working well.

In order to maintain efficient circulation, the PCV system also has a breather tube that allows clean air to enter the crankcase. This air is usually filtered through the engine air filter. But some vehicles have a separate air filter for the breather tube called the breather element. If this is the case with your vehicle, proper maintenance of the PCV will include replacing this element. To find out whether your vehicle has this type of PCV system, check your owner's manual or ask your service advisor at Matt Davis Auto.

The PCV system reduces harmful vehicle emissions. The maintenance it requires is simple and inexpensive at Matt Davis Auto. A fouled or damaged PCV system can lead to serious engine damage for Garner drivers.

Let's all learn to practice good car care. It's good for our wallets, and it's good for our NC environment.

Servicing High Mileage Vehicles at Matt Davis Auto

The price of gas and the uncertain economy are both causing NC residents to review their finances. More and more Garner drivers are opting to keep their vehicles longer and put off purchasing a newer car. It is estimated that two-thirds of the vehicles on the roads of North America today have over 75,000 miles/120,000 km on them. And the average age of vehicles is now over eleven years. That translates to some car care issues that many Garner men and women haven't dealt with in the past.

Older vehicles simply have different maintenance requirements than newer ones. Learning those requirements presents a challenge for people in Garner because many owner's manuals only publish maintenance schedules up to 60,000 or 90,000 miles (96,000 or 145,000 km). Vehicle owners have to keep good records and be more involved in planning preventive maintenance if they want to keep their vehicles on the road. First of all, any service in your owner's manual that comes with a recommended mileage interval should be continued at that interval.

For example, if it is recommended that you change your oil every 5,000 miles/8,000 km, you should continue to change your oil every 5,000 miles/8,000 km. The owner of an older vehicle has to recognize that his engine is operating under higher stress than a new one. It's just starting to show its age. So many experts suggest that the “severe service schedule” should be followed once a vehicle has racked up some serious road distance. On this schedule, the mileage interval for many services is shortened or should be performed more often. Check with your service advisor at Matt Davis Auto.

Garner drivers who own older vehicles should also be careful not to neglect or postpone oil changes. A full-service oil change is more critical for an older vehicle than for a new one. Older engines have had a lot of time to build up sludge in their oil compartment, so changing the oil at regular intervals is a must. Skipping an oil change compounds the sludge problem. With a full-service oil change, the vehicle's fluids are also checked and topped off. Your service advisor at Matt Davis Auto will also let you know if these fluids need to be replaced. Older vehicles have older seals and gaskets, which often develop tiny leaks. Regularly checking fluids will compensate for these leaks and offer a heads-up about any serious ones. So, again, it is important to stay on schedule and not skip or procrastinate a fluid check.

Older seals and gaskets begin to dry out and show their age by becoming brittle. High-mileage formulation oils and fluids can help extend the lives of these gaskets and seals. These products contain additives that recondition seals and gaskets and keep them from leaking. High-mileage formulas cost more than standard products, but in the long run they can pay for themselves by preventing more costly repair bills.

If a vehicle is getting on in years or mileage, its parts are as well. High-mileage car maintenance requires necessary repairs and replacements. Timing belts, radiator hoses, parts of the suspension system, anti-lock brakes, air bags, water pumps, alternators and batteries will not last forever and will wear out in higher-mileage vehicles. They need to be inspected regularly by your friendly and knowledgeable Matt Davis Auto service advisor and replaced as necessary.

But don't go running for the new car lot just yet. These repairs may sound like a lot, but in total, they're still cheaper for Garner drivers than new car payments. And if you stay on top of them and budget for them, they aren't as burdensome as it may appear.

If you plan on driving your vehicle into its high-mileage years, there are two relationships you need to develop. The first is with your Garner service center. Matt Davis Auto can offer you invaluable auto advice and help you develop a service plan that is right for you and your vehicle. Second, you need to develop a relationship with your vehicle itself. You don't need to name it, but you should become familiar with its noises and idiosyncrasies. Pay attention to changes in its habits such as new or unusual sounds, smells, vibrations, etc. Taking note of such things and sharing them with your service advisor can help stave off a lot of big-ticket repair issues.

As we get older, keeping up with a diet and exercise plan becomes more and more critical to maintaining good health. It's the same with our vehicles. A preventive maintenance plan and smart vehicle care will keep them on the road and keep them safe for a good many years to come.

Transmission Service at Matt Davis Auto in Garner

Let's talk about transmission service. It can be easy for Garner drivers to forget about getting their transmission serviced because it doesn't need it very often. It's easier for people in NC to remember to change the engine oil - you know, every 3,000 miles or 5,000 kilometers. But proper transmission servicing keeps your vehicle running smoothly and helps you avoid repairs down the road.

The transmission undergoes a lot of stress. The grit you can see in used transmission fluid is actually bits of metal that wear off the gears in the transmission. In addition to that, the transmission operates at very high temperatures. Usually, it's much higher than engine temperatures. Those high temperatures eventually cause the transmission fluid to start to break down and lose efficiency.

As the fluid gets older, it gets gritty and doesn't lubricate and cool the vehicle transmission as well - leading to even more wear. The fluid can actually get sludgy and plug up the maze of fluid passages inside the transmission. At best, your transmission won't operate smoothly. At worst, it could lead to damage.

When your transmission is running properly, it transfers more power from your engine to the drive wheels and improves fuel economy. That's why it is recommended to change your transmission fluid at regular intervals. Your owner's manual has a schedule for transmission service and, of course, your service advisor at Matt Davis Auto can tell you what is recommended.

Hot and dusty Garner area conditions, towing, hauling, stop-and-go driving and jackrabbit starts all begin to increase the load on the transmission and its internal temperature. That means Garner vehicles with these types of transmission requirements need to change the fluid more often. A good rule of thumb is every 35,000 miles, 55,000 kilometers or two years. If your owner’s manual suggests more frequent intervals or if you're driving under severe service conditions around the Garner area, you will need to change it more often.

Most Garner auto service centers (including Matt Davis Auto) have the ability to perform a transmission service while you wait and the cost is quite reasonable. It's downright cheap when you think about how much a major transmission repair can cost! Our pros at Matt Davis Auto will know the right type of transmission fluid to use. If it's getting to be time to have your transmission serviced, do your vehicle a favor and have it done.

The Fallacy of Cheap Tires

Do you ever shop for shoes in one of our Garner area shoe stores?
When buying a running shoe, is quality important?
Does durability matter as long as the shoes look fabulous?
Would you rather have one pair of long lasting shoes or two pair of lower quality shoes at the same price?

Is the warranty important when buying tires?
When you choose new tires in Garner, what's the most important factor for you?

Give us a call at Matt Davis Auto at (919) 600-5125 for tire recommendations.

You know, buying tires in Garner is a big deal. It's a big ticket item so you know you'll be spending a lot. You're not only concerned about the price, but you want to know that it'll be a long time before you need to buy new tires again.

And of course there's the safety aspect as well. The tires do a lot of work – they carry the weight of the vehicle and you and your passengers. They need to be up to the task. You want to be sure they hold the road and provide good traction. If you carry heavy loads or tow a trailer, the tires need a high load rating to be up for the job.

As a tire professional, I think it's important that people understand the effect of price on a tire's performance and durability. When I was a kid, my dad had a saying, "Pay twice as much and buy half as many."

Dad applied that to a lot of things. He thought that one high quality suit would last longer and look better than two cheap suits. The saying really seems to hold true when it comes to shoes and boots, too.

I buy high-quality work shoes because I spend a lot of time on my feet. They're more comfortable, have important safety features like steel toes and non-slip soles and they last at least twice as long as cheap shoes. I feel I get very good value for my money.

I apply the same thinking to tires. The major tire brands that you're familiar with are known as Tier 1 tires. These tires are well-engineered and very high quality. Comparable tires are usually in the same price range from brand to brand.

Stepping down in price you come to private label tires. Some large tire store chains carry tires with the chain's own brand. It's important to know that most private label tires are built by the same Tier 1 brands that you are familiar with, so they are a quality product. You can ask your tire professional who makes their private brand.

The lowest priced tires on the market are Tier 3 tires. These tend to be imported from China or South America. Since you get what you pay for, you can't expect a Tier 3 tire to deliver the same performance and durability as the others.

So let's say you need new tires. You've determined the features you need. So you have several options, including price options. Now, you've probably heard the term 'it's a 40,000 mile/64,000 km tire' or 'it's a 60,000 mile/97,000 km tire'. Simply put, the manufacturer warrantees the tire for 'X' number of miles/kilometers. If that's important to you, look for the warranty.

What's the difference in the tires with higher mileage warranties? It's the rubber compounds and the amount of tread material. As you might expect, you'll pay more for the longer-lasting tire.

Now the cheapest tires you can find won't have a manufacturer's mileage warranty, or if it does, it'll be relatively low. That brings us back to dad's saying; if you buy the cheapest Tier 3 tire you can, you will likely go through two sets in the time it would take to wear out one set of good quality tires. And the good tires won't cost twice as much, so you'll end up paying more per mile/km driven with the cheap tires.

Hey, I realize that sometimes the budget will only allow for a Tier 3 tire. I make them available for my customers who need them because I would rather see them driving with safe, new tires than pushing their old tires beyond their safety limits. But at Matt Davis Auto, we always counsel our customers to buy as much tire as they can afford, because it will be much less expensive in the long run.

Your tires are the only parts of your vehicle that touch the road. You're only as safe as your tires are well built.

Buy value – not price.
