Engine combustion creates tremendous amounts of energy from the pressurized mixture of air and fuel. But did you know that the engine produces more power than it actually uses? The excess power comes out in the form of exhaust gases. These by-products are actually wasted energy from combustion. If these wastes remain in the engine, it will clog the parts and compromise overall performance. That's why the PCV Valve (Positive Crankcase Ventilation valve) is an important component of your car.
This valve serves as a vent for the upper engine. It prevents unwanted by-products from re-entering from the internal combustion system. It also separates the unwanted by-products from the combustion chamber. After that, the valve funnels the by-products to the exhaust system, where they are guided out of your car through a series of pipes. If it fails, the by-products accumulate in the crankcase, causing your engine to become overworked and worn out.
You can easily diagnose if your PCV Valve is malfunctioning. The first thing to look for is an indication of a malfunctioning air intake system. When the valve is broken, dirt build-ups in your air filter will make your car's fuel consumption inefficient. If that's the case, you should get a PCV valve replacement as soon as possible. Replacements are not expensive, and they can be easily installed. In choosing a replacement, make sure it fits your car specifications and passes OEM standards.
