How did we estimate these prices?

Jerry's experts researched and collected data from 2500+ real repair shops in all 50 states in the US, including everything from the total cost of repair services to the hourly labor cost for mechanic labor in each shop. We combined that data with our expert database of hundreds of real repair jobs, thousands of real cars, millions of real car part prices in order to best estimate the cost of each repair service. Our labor cost estimate is calculated by taking the average hourly labor rate for a certified mechanic in the US, times the number of hours it takes on average to complete a repair. We recommend you compare your local shops with Jerry and contact those shops directly to get final pricing for your vehicle.

What parts do I need for my positive crankcase ventilation (PCV) valve replacement and how much do those parts cost?

In most cases, there’s just one part you’ll need for a positive crankcase ventilation valve replacement:
  • Positive crankcase ventilation valve: The PCV valve helps route exhaust gases from the engine crankcase back to the air intake manifold, where they can enter the combustion process again. For most vehicles, you can usually expect a PCV valve to cost less than $20.
Some reputable brands we recommend include ACDelco, Fram, and Motorcraft for reliable and quality PCV valve replacements. You can typically purchase these brands from retailers such as AutoZone, RockAuto, and NAPA Auto Parts, both online and in-store. However, like price, recommended brands may also vary depending on your vehicle's specific year, make, and model.
It’s usually a good idea to stick with an OEM part when replacing your positive crankcase ventilation valve, especially since they’re relatively cheap anyway. If you prefer to explore your aftermarket options, you’ll want to confirm that they meet the specifications your vehicle requires.
You can find replacement positive crankcase ventilation valves at most auto parts stores, such as  AutoZone, RockAuto, and NAPA Auto Parts—and they’re usually pretty affordable. You could also purchase them via Amazon or a dealership.

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: 
  1. Inspection: Your mechanic will take a look under your car’s hood to locate the PCV valve and inspect it and any surrounding parts for evidence of damage or faulty performance. They might also use an OBD-II scanner to check for error codes related to the emissions system to check for other potential problems.
  2. Remove and replace the PCV valve: If your mechanic determines there’s a problem with the PCV valve—or you’ve reached the mileage interval when it’s time for a replacement—your mechanic will remove the old PCV valve. This is often just a matter of unplugging it from its rubber grommet on a valve cover and connecting PCV valve hose clamps but can vary slightly with different vehicles. Then, they’ll reinstall the new PCV valve.
  3. Quality assurance check: Depending on the symptoms you experience, the mechanic may check for error codes, run your engine, or test drive the vehicle for a time to ensure all parts of your vehicle’s emissions systems are working properly.

What happens if I don’t replace my positive crankcase ventilation (PCV) valve?

A failing positive crankcase ventilation valve can throw off the engine’s air-fuel ratio during the combustion process. This can lead to worsening gas mileage, and you also risk having excess sludge buildup in your engine.
If you take too long to replace a failed PCV valve, you could risk serious long-term damage to your engine.
Keep an eye out for these warning signs that can point to a problem with the PCV valve:
  • Visible damage to the PCV valve
  • Poor gas mileage
  • Rough-running engine
  • Oil leaks
  • Hissing or whistling engine noises
  • An illuminated check engine light
  • Excessive engine oil consumption
Keep in mind: Many of these symptoms can also be linked to other problems with your vehicle’s engine or emissions system. A certified mechanic can properly diagnose your vehicle’s problems.

What is a positive crankcase ventilation (PCV) valve?

A positive crankcase ventilation valve—known as a PCV valve for short—is a one-way valve that allows exhaust and unburned fuel to make its way out of the crankcase in your car’s engine and back into the intake manifold, where they can re-enter the combustion process.
The PCV valve helps reduce harmful emissions and plays a crucial role in ensuring that too much sludge doesn’t build up in the engine, which would lead to serious (and seriously expensive) damage.

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
  • Oil leaks (likely from blown engine seals or gaskets)
  • Rough engine idling
  • Reduced fuel economy
  • Failed emissions test

How often should a positive crankcase ventilation (PCV) valve be replaced?

Common replacement intervals can range from 20,000 to 50,000 miles, but you should check your owner’s manual to see if your vehicle’s maintenance intervals include a recommendation for PCV valve replacement. 
Outside your vehicle manufacturer’s recommended replacement intervals, the only time you should need to replace the PCV valve is if it’s been prematurely damaged. Some PCV valves can develop clogs if enough oil or sludge builds up inside them.

Can I replace my positive crankcase ventilation (PCV) valve myself?

The process of replacing a PCV valve is simple overall, and some will find this to be a surprisingly quick and easy DIY car repair. That said, some vehicles’ PCV valves are more complicated or challenging to access than others.
If you don’t feel comfortable replacing a PCV valve yourself, you should have a professional mechanic take care of the job for you.

FAQs

The cost of the PCV valve part itself is relatively inexpensive and can often range from $10 to $20. If you have your PCV valve replaced by a mechanic, you’ll need to account for labor costs as well, which can often result in a total bill around $87 on average.
Keep in mind: If your vehicle is still under warranty, you might not have to worry about paying for a replacement PCV valve out of pocket.
Here are some of the most common symptoms of a failed PCV valve:
  • Illuminated check engine light
  • Engine misfiring
  • Hissing or whistling noises from the engine
  • Oil leaks (likely from blown engine seals or gaskets)
  • Rough engine idling
  • Reduced fuel economy
  • Failed emissions test
Since many failed PCV valve symptoms are similar to those with other engine issues, a certified mechanic can help you determine the root cause of your problem.
A positive crankcase ventilation system or PCV system helps reduce harmful exhaust emissions—and it also reduces sludge buildup in your engine. 
If too much oil and sludge start building up in your engine on account of a faulty PCV valve and the issue goes unaddressed for too long, it could lead to serious damage and reduce your engine’s lifespan.
Since PCV valve parts themselves are relatively inexpensive, it’s usually best to replace them as soon as possible—that way you won’t have to deal with more costly problems later.
