Besides, the PCV valve also helps keeping the oil and the engine in proper shape extending their life as well. Also, its mechanism is very important for preventing the appearance of engine corrosion as well as it helps improving fuel economy. The PCV valve routes crankcase partially burned gases back to the engine.
The valve itself operates on a vacuum, so the hoses are technically vacuum lines. As you can imagine, your carâs PCV valve and PCV valve hose are subjected to high temperatures whenever the engine is operating, as well as being exposed to caustic gases. In addition, the PCV valve and hose are in use as long as the engine is running. Combined, this means thereâs a significant potential for wear and tear. In terms of predicted lifespan, thereâs really no set time limit for your PCV valve hose.
