How long does the PCV valve hose last?

Your car's engine needs both air and gasoline to run. During combustion, gases are also formed. These gases contain traces of gasoline and can be re-burned by injecting them back into the intake manifold. This improves engine performance and also reduces fuel consumption. The PCV (Positive Crankcase Ventilation) valve is the component responsible for collecting these gases and returning them to the engine.

The PCV valve requires a pair of different hoses (exact configuration varies by vehicle make and model). Hoses are mainly used to inject said gases into the intake manifold. The valve itself runs on a vacuum, so the hoses are technically vacuum lines.

As you can imagine, your vehicle's PCV valve and PCV valve hose are exposed to high engine temperatures and corrosive gases. In addition, the PCV valve and hose are used while the engine is running. Taken together, this means that there is significant wear potential.

In terms of life expectancy, there really is no set time limit for your PCV valve hose. Since it is made of rubber, the PCV valve hose wears out over time and needs to be replaced, but this time can vary greatly depending on a number of different factors, including how often you drive, how long the engine is running during each trip, like a well maintained engine and many others.

If a PCV valve hose fails, you are bound to run into problems including loss of power and reduced fuel consumption, so it is important to be aware of the signs to look out for, which could indicate that your hose (or the PCV valve itself) is faulty or out of order. already failed. These symptoms include:

• Check Engine Indicator
• Hissing sound from the engine compartment (indicating a hole in the vacuum hose)
• The engine runs unevenly at all speeds
• Engine has uneven (rough or "jumping") idle
• No power or response when stepping on the gas pedal
• Reduced fuel consumption

If you notice any of these symptoms, it's important to check both the PCV valve and the PCV valve hose. If one of them fails or has already failed, they must be replaced.
