Positive Crankcase Ventilation ? PCV Valve Service at Matt Davis Auto

Hello Garner! Did you know that the first federally-mandated emissions control device was introduced in the 1960's? The Positive Crankcase Ventilation valve, or PCV valve, has been installed in NC vehicles since 1964 and represents the first legislation by the United States government to regulate harmful emissions as well as to improve performance in the country's vehicles.

The PCV valve, as you can probably guess, is located on the crankcase. The crankcase is the lowest part of a vehicle's engine. It houses the crankshaft and the engine oil. The crankshaft connects to the pistons that power the engine.

Pistons are pushed down when fuel is burned in an engine. This causes the crankshaft to rotate, which sends power to the transmission.  It ultimately turns the axles and causes the vehicle to move. Some of the gases released by the burning fuel squeeze around the pistons and down into the crankcase.

If the escaped gases mix with the engine oil in the crankcase, oil sludge develops. This sludge has the consistency of petroleum jelly and can cause damage by clogging up passageways in the engine. Further, escaped gases can build up pressure inside the crankcase that can blow out seals and gaskets.

Before 1964, a hose was attached to the crankcase that vented escaped gases out into the air. These gases contained about 70% unburned fuel as well as harmful emissions. The PCV valve was designed to curb these harmful emissions as well as recapture unburned fuel.

The PCV valve is a small, one-way valve that allows escaped gases to exit the crankcase. The gases are then routed into the intake system so they can be re-burned in the engine. Fresh air enters the crankcase through a breather tube to facilitate this circulation and keep the air in the crankcase clean.

The PCV valve, like most working parts on a vehicle, will wear out over time. Usually it simply gets gummed up. Preventive maintenance, including routine oil changes at Matt Davis Auto in Garner, will extend the life of the valve, but eventually it will have to be replaced. A sticking PCV valve won't allow gases to circulate properly, which can increase pressure in the crankcase. Over time, that pressure will lead to oil leaks.

Your vehicle manufacturer recommends that a PCV valve be replaced every 20,000 to 50,000 miles (32,000 to 80,000 kilometers), depending on the vehicle and Garner driving conditions. It's an inexpensive repair but may not be included in the maintenance schedule in your owner's manual.  So if you're looking for auto advice about the PCV valve, you may have to ask our pros at Matt Davis Auto.

Taking care of our PCV valve protects the environment in NC and improves vehicle performance. It's just part of good vehicle care for Garner drivers and a way all of us can do our part to improve the world we live in.

Garner Customer Detective Work

One might say the most challenging part of being an automotive service technician at Matt Davis Auto is diagnosing a problem before it can be fixed.

Cars are made up of a bunch of complex systems. There usually could be a number of reasons for any given symptom. So, it's challenging to track down the actual cause of the problem. And it can be frustrating for the vehicle owner because it can take time and money to get to the bottom of a problem. If it's not something obvious, it's easy for the customer to focus on the fixing and not the diagnosing.

Let us at Matt Davis Auto introduce you to something we'll call 'Customer Detective Work' –  helping your technician find clues to what's wrong.

We start with the detective basics: What, Where and When. Play along with me; You come in to Matt Davis Auto and your car is making a funny sound...

• Q: Where's the sound?
• A: Around the right front wheel.

• Q: What kind of sound?
• A: Kind of a clunk, clunk sound.

• Q: When do you hear the sound?
• A: When I turn and accelerate. 

• Q: Right and left? Forward and back?

Do you see where we're going? You're gathering additional information to help your technician at Matt Davis Auto know where to start. Based on your car and the tech's experience, he'll know where to look and can start with the obvious suspects.

You can see how that would be more helpful than dropping the car off with a note that says "making a funny noise."

If the tech can experience the problem personally, he's better able to make a diagnosis and repair and then test to see if the repair solved the problem.

I Had No Idea! (Four Things You Didn't Know About Vehicles)

Bet you didn't know:

Some of the earliest rearview mirrors were marketed as "Cop Spotters" so drivers would know when police were following them. Who wants a ticket, anyway? According to eBay Motors, Elmer Berger first patented a rearview mirror that was mounted on the front fenders, on the spare tire secured to the side of the car of at the top of the driver's door frame. 

About 80 percent of your vehicle is recyclable. So says The Balance. That means four-fifths of most vehicles can be recycled.  Much of that recycling is done by automotive aftermarket recyclers.  Between the U.S and Canada, they reclaim enough steel to produce 13 million new vehicles.

The man who invented the first modern cruise control couldn't even drive a car because he was blind! His name, says Smithsonian.com, was Ralph Teetor.  Blinded at a young age by a knife accident, Teetor was inspired to create a speed control by a couple of things.  One, the U.S. imposed a mandatory 35 mph/55 kph during World War II to conserve fuel and tire rubber, and Teetor wanted drivers to go a safe and steady speed.  Plus, a chauffeur who drove him around used to randomly slow down and speed up which irritated Teetor.  So he invented a speed control to encourage drivers to drive at a more constant and safer speed.

The first grooved tires were invented in 1904 by Continental.  But that was a big improvement over the very first "tires" which were actually metal hoops that made riding in the first cars a pretty rough experience.  The first rubber tires were solid rubber, not inflatable like today's tires.  Things have come a long way.  Modern tires are made with sophisticated rubber compounds that can deal with heat and cold.  Plus their tread patterns help drivers get better traction on wet roads when it storms.  Still, it's important to make sure yours have enough tread and are properly inflated for maximum safety and performance.

Quite frankly, there's a lot we don't understand about the vehicles we drive.  They're much more complicated than the old horse and buggy that preceded  them.  Leave your vehicle's maintenance and service to highly trained technicians who DO understand how to maintain, diagnose and repair today's modern, sophisticated vehicles.

What Garner Automotive Service Consumers Should Know

There are some things drivers should know about Garner car service and repair. First and foremost, Matt Davis Auto cares about you and your family's safety. And we really appreciate your business. Matt Davis Auto in Garner wants to build a trusting relationship that becomes the foundation for a mutually beneficial experience for years to come.

Building on that foundation, there are some things that would help you understand the auto service and repair business better. First, it can be really hard to fix vehicles. The days of shade tree mechanics are long gone. The majority of automotive systems are computerized. It takes a lot of training and very expensive equipment to diagnose and repair modern vehicles. The pros who work for Matt Davis Auto need extensive computer training – not just how to run the diagnostic systems, but also searching for the right parts, networking with other technicians to help them with a difficult problem and pulling together a job order that makes sure that each step of the process is addressed.

The threshold for getting started as a technician gets higher all the time in NC, and there is a huge commitment to on-going training every year. This training takes time and money. It contributes to business overhead. Average consumers in Garner may not realize the business and environmental regulations Matt Davis Auto must comply with. Of course that costs money, too. Like any NC business, overhead is a big factor.

When you go into your favorite Garner area restaurant, you don't value the meal by what the food would cost at the grocery store. The restaurant has rent, wages, insurance, taxes, utilities, professional fees, equipment, supplies – you get the picture. The restaurant has to charge enough to not only pay for the ingredients, but for all these other things as well while making enough profit to remain in business. If you value the meal and are satisfied with your dining experience, you'll come back and tell your friends.

It's the same for Matt Davis Auto. The value of its service is not the cost of the parts they replace, but in your satisfaction with the results. If they deliver a good product at a fair price, customers are happy to see them succeed as a NC automotive business.

At Matt Davis Auto, we love to see our Garner customers whenever they come in, but we would much rather see them three or four times a year for routine maintenance than once a year on a tow truck. We want to work together with you to avoid breakdowns. Tell your friends and family to come in for their scheduled maintenance too. That lowers our marketing costs and helps keep labor rates down. That's good for everyone in Garner.
