Your gasoline engine goes through some exhausting work. Yes, it's truly exhausting, as in: it produces exhaust! And when your engine starts behaving like it's exhausted, such as running poorly or getting lousy fuel economy, the trouble may be something called a PCV valve.
Did you know it's a series of explosions that creates the power in your engine? The spark plugs ignite a mixture of gasoline and air and BANG! A whole bunch of those and you're engine is humming away. Leftover vapors from those explosions go into your crankcase, which is also a place where engine oil goes. Those vapors still have a lot of unburned fuel in them, and if they had nowhere to go, they'd turn your oil into a thick mess called sludge, not good for a smooth running engine.
Engineers came up with an idea. Re-direct those gasses building up in the crankcase into the engine's air intake and mix them with fresh air. That way the unburned fuel could go through the engine again and produce power. It also means the unburned fuel doesn't pollute the air. The part that makes that happen is called the Positive Crankcase Ventilation (PCV) valve.
Besides reducing pollution and preventing the oil from turning to sludge, the PCV valve also relieves pressure in the crankcase, reducing the potential for oil to leak. One of the reasons you should get your oil changed as frequently as your vehicle's manufacturer recommends is that it helps reduce chances for problems with the PCV valve.
After a while, the PCV valve can itself get gummed up and stick, and the driver may notice oil leaks, reduced power or engine hesitation. That's why it's important to make sure the PCV valve is operating like it should, and often it can be diagnosed during a visual inspection by our technicians. Replacing a PCV valve is usually quick and inexpensive. After it's done, your vehicle will run with the performance and fuel economy you're used to. Goodbye exhaustion!

The internal combustion engine in your vehicle counts on two things that mix together to be burned in the engine for power: fuel and air. Both are important, of course. If you run out of fuel, your engine wont run at all. Since theres plenty of air around, you wont run out of air, but you coul... More

If you have a vehicle with an automatic transmission, you probably never think about gear shifting. When motor vehicles were invented, all of them had to be shifted manually. But that wonderful self-shifting transmission, referred to these days as simply an automatic, changed everything. Automa... More

You're heading down the road and you notice your vehicle is sputtering, like it's running out of gas. But the gauge show's it's still got a quarter of a tank. So what gives? It could be that your fuel pump is failing, meaning your engine is not getting enough gas to run properly. While fuel pu... More
