What is the Positive Crankcase Ventilation (PCV) Valve all about?

The PCV Valve transfers gasses from inside the crankcase to the intake manifold where they are burned as part of the normal combustion process. Excess fumes are burned by the engine, rather than released into the atmosphere.

Keep in mind:

PCV valve failure can be caused by other engine problems. To ensure that this is not the case, a mechanic should test your engine after replacing the PCV valve, to make sure that the car runs well and doesn’t have other issues.

How it's done:

  • Disconnect the vacuum hose.
  • Remove and replace the PCV valve.
  • Replace PCV hose if appropriate.
  • Install vacuum hose.

Our recommendation:

In general, it is a good practice to replace the PCV valve during every major tune-up. Changing the engine oil and flushing the engine on a regular basis will prevent sludge build-up inside the oil pan that may cause the PCV valve to fail.

What common symptoms indicate you may need to replace the Positive Crankcase Ventilation (PCV) Valve?

  • Leaks in the engine compartment.
  • Leaks underneath the car.
  • A hissing noise from the engine.
  • Car runs poorly.

How important is this service?

As excess gas accumulates in your crankcase, the PCV valve redirects it through the intake manifold, where they are used as a normal part of your engine’s process. When the PCV valve fails, your engine won’t redirect this excess gas that it depends on. As such your vehicle will not run smoothly, and it will likely get much worse gas mileage.

Mercedes-Benz C320 V6-3.2L - Power door locks are not working - Phoenix, Arizona
I have had a bad experience with Your Mechanic from the very beginning. I'm a first time customer. I scheduled my very first appt. with Your Mechanic. 30 min past the scheduled time YM was suppose to be at my place, I get a text saying he won't be able to make it. So I rescheduled for the next available time which was 3 days later. I get another cancellation notice from YM. At this point I was really disappointed and frustrated I had made special arrangements to be available for both scheduled appts. Finally He shows up 30 min past the scheduled appt, He does a inspection on my issue, looks at it then tells me he cant work on it wrong part.. So he finished up. He told me that I should only be charged $25 or $30 dollars for this appt. He spent less than an hour. He assured me he put in his notes to YM to adjust my account accordingly. Well of course my account was not adjusted to reflect that amount. So I called customer service at YM and spoke with Paul Who put in for a refund and expedite my claim. Said it would be 24-48 hours. before I would receive a response from YM management. I have had to go through so much unnecessary drama just to have a mechanic look at my car issues. To be honest this is not a very good first impression I have of YM. Robert was nice and seem to know what needed to be done for my car. But my experience with YM has been bad from the start and I am not pleased at all. I just would like my refund and that will be all I would like to hear from YM.
