PCV Valve: What Is It?

Most Rockford 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. Rockford 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 TJ's Auto Center Inc..

The PCV system reduces harmful vehicle emissions. The maintenance it requires is simple and inexpensive at TJ's Auto Center Inc.. A fouled or damaged PCV system can lead to serious engine damage for Rockford drivers.

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

Tracking True in Rockford: Wheel Alignment

At TJ's Auto Center Inc., we occasionally see severe tire damage that could have been prevented with proper wheel alignment. During a TJ's Auto Center Inc. alignment service, your vehicle is put on an alignment rack where the tires, steering and suspension parts are inspected for problems. Then the alignment is charted and checked against the vehicle factory settings. Adjustments are made to bring the wheels back into alignment. This gets all four wheels moving in precisely the same direction.

If you don't remember hitting a pothole, how do you know if your wheels are out? The most obvious sign is that your vehicle pulls to one side. Also, your steering wheel may not be centered when you're going straight. If you're in the habit of checking your tire wear regularly, you may notice the edges of one or more tires rapidly wearing down. You should have your Rockford auto service center look it over. Of course, if you've been in an accident, you should get your alignment checked.

It's not surprising that a forceful impact can seriously knock tires out, but remember that a series of smaller ones can add up. That's why your vehicle manufacturer recommends periodic alignment checks. If your vehicle owner's manual doesn't advise a specific interval, once a year might be appropriate. Check with your TJ's Auto Center Inc. service advisor. As with most other preventive maintenance services, the cost of the alignment is a heck of a lot cheaper than having to purchase new tires earlier than expected.

The TJ's Auto Center Inc. Guide to Proper Fluids for Your Vehicle

The automotive professionals at TJ's Auto Center Inc. would like to give Rockford drivers an update on some of the things happening in automotive fluids. You know, vehicles are becoming more sophisticated every day.  Fluids such as, oil, coolant and transmission fluid are becoming more specialized at about the same pace.

The Rockford do-it-yourselfer has to be pretty careful so that they do not actually harm their vehicle with the wrong type of fluid. That is why so many Illinois ] owners rely on the advice of their friendly and knowledgeable TJ's Auto Center Inc. service advisor to not only get the correct family of fluids, but to suggest the formulation that is best for their vehicle and their driving habits in the Rockford area.

Let's start with engine oil. Rockford drivers who have been paying attention will have noticed a number of new oil weights on the Illinois scene in the last several years. Modern engines are built to much tighter tolerances and have very complicated valve trains. The oil must be thin enough to lubricate complicated parts when the engine is cold. The weight of an oil is expressed in terms like 20-W-50 or 5-W-30. The vehicle manufacturers recommend the weight of oil for each vehicle they make. The recommendation is based on engine design. Your Rockford service center will know what weight your vehicle manufacturer recommends - and it's important to follow those recommendations. Your service advisor at TJ's Auto Center Inc. can also offer suggestions for special formulations and can tell you all about conventional and synthetic oils.

Antifreeze, or engine coolant, is another area that has become more complicated. For a long time, vehicle manufacturers only recommended a couple of different types of coolant. Now, several different formulations are needed because of the high-tech materials that vehicle manufacturers are using to build the cooling system. Using the wrong type of coolant in your vehicle can actually void your warranty, so it's important to get that right.

Transmission fluid is becoming specialized for Rockford vehicles as well. New transmission designs have particular requirements that require specific formulations. Recently, new, somewhat confusing, standards for brake fluid have also been released.

Not too long ago, there was a good chance that all of the vehicles at your house would use many of the same fluids. However, as automotive technology advances, the array of basic automotive fluids Illinois drivers need will grow. And, some of the formulations will cost a little more for Rockford drivers. Fortunately, TJ's Auto Center Inc. will continue to update their training to keep pace with technology so that you'll get the right fluids your vehicle needs. It's all part of the commitment we make to your driving peace of mind.
