How will a mechanic replace my positive crankcase ventilation (PCV) valve?
The exact steps to replace a PCV valve may vary slightly depending on your vehicle’s setup, but here’s generally what a mechanic will do to take care of the replacement:
- Inspection: Your mechanic will start by inspecting the PCV valve and its surrounding components under the hood. They'll check for any signs of damage or malfunction and may use an OBD-II scanner to scan for error codes related to the emissions system.
- Removal and replacement: If the mechanic identifies a problem with the PCV valve or if it's due for replacement based on mileage intervals, they'll proceed to remove the old PCV valve. This typically involves unplugging it from its rubber grommet on the valve cover and disconnecting any associated hose clamps. Then, they'll install the new PCV valve.
- Quality assurance check: Depending on the symptoms observed, the mechanic may conduct further tests such as checking for error codes, running the engine, or taking the vehicle for a test drive to ensure optimal functioning of the emissions system.
What happens if I don’t replace my positive crankcase ventilation (PCV) valve?
A malfunctioning positive crankcase ventilation valve can disrupt the engine's air-fuel ratio during combustion, resulting in deteriorating gas mileage and potential accumulation of excess sludge in the engine. Delaying the replacement of a faulty PCV valve poses the risk of significant long-term damage to the engine.
Keep an eye out for these warning signs that can point to a problem with the PCV valve:

What is a positive crankcase ventilation (PCV) valve?
A Positive Crankcase Ventilation (PCV) valve serves as a crucial component in your car's engine system. Its primary function is to enable the controlled release of exhaust gases and unburned fuel from the crankcase, allowing them to re-enter the intake manifold for combustion. This process aids in minimizing harmful emissions and preventing excessive sludge buildup within the engine, thus averting potential costly damages.
When should I replace the positive crankcase ventilation (PCV) valve on my car?
You should replace a faulty PCV valve if you notice the following:
- Illuminated check engine light
- Engine misfiring
- Hissing or whistling noises from the engine
