Positive Crankcase Ventilation ? PCV Valve Service at TJ's Auto Center Inc.

Hello Rockford! 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 Illinois 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 TJ's Auto Center Inc. in Rockford, 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 Rockford 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 TJ's Auto Center Inc..

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

Hey Rockford Drivers: How Do You Save Gas?

Higher Rockford fuel prices aren't going away any time soon. That's not good news for our wallets. A lot of Rockford drivers are trying to find ways to cut down on fuel consumption and hang on to some of their hard-earned money.

North Americans drive billions of miles less during months of high fuel prices. That's right, billions. Of course Illinois vehicle owners can't stop driving altogether, so we still need to find other ways to cut fuel bills.

Preventive maintenance at TJ's Auto Center Inc. in Rockford and good vehicle care can actually pay for themselves by lowering our fuel consumption. Here's a real-life example of how that can work.

A family planned a four-day camping trip. Before leaving, they took their SUV into TJ's Auto Center Inc. for an oil change. They flushed the cooling system, serviced all three differentials and cleaned the fuel system. They replaced the PCV valve and breather element. Then they checked the tires to ensure they had enough air.

This was several hundred dollars in maintenance and repair. You may be thinking how the family could possibly recoup the cost in gas and save money. First of all, the repairs all needed to be done anyway. Even if the costs aren't recouped, many of them will pay for themselves by preventing even more costly repairs later. Also, the family had planned and budgeted for the routine maintenance, so it didn't cut into their trip allowance.

The SUV pulled a one-ton trailer and hauled everything the family needed on their camping trip. At the end of the trip, the owner was surprised to learn the SUV had actually gotten better gas mileage than it ever had before—even with that heavy load. The repairs and maintenance at TJ's Auto Center Inc. had improved the gas mileage by 25%! The family saved $48.00 in gas on their four-day trip. And they are continuing to reap rewards from the improved mileage.

So what can you do to save fuel? First, stay caught up on routine maintenance at TJ's Auto Center Inc.. Almost every maintenance item listed in your owner's manual will maintain or improve your fuel economy. Second, take your vehicle into TJ's Auto Center Inc. for scheduled tune-ups. And third, take care of needed repairs. You may be surprised at how much you save at the pump and probably with the improved vehicle performance as well.

If your Check Engine light is on, find out why and take care of it. Some of the problems that set off that warning light can seriously reduce fuel efficiency.

As you schedule preventive maintenance, don't forget your tires. Proper tire pressure and wheel alignment are both essential to good fuel economy.

Here's some more auto advice about some simple things you can do to improve fuel economy, beyond maintenance and repairs:

Dump the junk. More weight in your car equals more fuel. You'd be surprised how much stuff people carry around in their cars. That adds up to a lot of extra fuel. One hundred pounds of extra stuff in your vehicle can add up to the loss of one mile per gallon of fuel.

Get the lead out. No, don't speed up, slow down. Get the lead out of your right foot. The single biggest drain for most Rockford vehicles is speeding or sudden accelerations. Slow down and go easy on turns and lane changes, and don't treat every stoplight and stop sign like a green flag. These small changes can add up to quite a bit of change in your pockets.

We haven't mentioned the pills you can drop in your gas tank or special devices you can hook on your fuel line in order to increase fuel efficiency. There's a simple reason for that: they don't exist. There may be some truth behind some of these claims, but most of them are full-out scams. And if any of these things do actually help, it's not nearly as much as the things we've listed here.

Be smart. Your vehicle and your wallet will thank you for it.
