PCV Valve Replacement

A PCV ( Positive Crankcase Ventilation) valve is an object in your car that manages its emission control system. (Not every car has a PCV valve, though.) It’s vital to check it to make sure that it doesn’t get clogged with contaminants. A clogged PCV valve results in loss of gas mileage, decreased speed, and power loss. If your PCV valve does get clogged, change it as soon as possible. Here are the steps for PCV valve replacement:

1. Find the PCV Valve

The PCV valve is located on the top half of the engine, also known as the crankcase. The valve may either have one rubber hose coming out of one end or be located between two hoses. Consult your service manual to be certain of the PCV valve’s location.

2. Remove the PCV Valve

Once you found the PCV valve, you need to remove it. If the valve is attached to the crankcase, take some needle nose pliers, and pull it out. If the valve is placed between two hoses, it shouldn’t require tools to get it out.

3. Check the Hose and Grommet

Before installing the new PCV valve, make sure that the hose and grommet are in good shape. Blow through the hose. If it’s dry and brittle, replace it. Replace the grommet if it’s deteriorated.

4. Install the New PCV Valve

Attach the new PCV valve to the hose. Make sure that it is screwed in securely, but don’t tighten it too much. Depending on your maintenance needs, the valve itself may be the only thing that has to be replaced, but sometimes you may need to install new hoses as well.

5. Start Your Car

Run the engine of your car and check for leaks.

In a different scenario, you probably don’t have time to do this on your own and don’t mind paying a mechanic to do the job. PCV valve replacement cost is between $56 to $79 but could vary on many factors such as car type and what your mechanic may charge.
