Frequently asked questions about PCV valve change & replacements

Read our answers to questions about PCV valve replacement costs, symptoms and more.

What does a PCV (positive crankcase ventilation) valve do?

The valve is part of the positive crankcase ventilation system that is attached to the engine. Simply put, the system recirculates the harmful gases that develop inside the crankcase back into the cylinders to be reused in another combustion cycle. The valve regulates how much of and when the gases are recirculated back into the cylinders.

What does a pcv valve replacement involve?

  • Mechanic will inspect the PCV system and valve for leaks.
  • If necessary, the mechanic will replace the PCV valve, by disconnecting the PCV's hoses.
  • Mechanic will advise if any other parts need to be replaced (like the oil filter).
  • Mechanic will reconnect the hoses.
  • Mechanic will run the engine and, if necessary, test drive the car.
  • Adjustments are made where necessary.

Can I do a pcv valve replacement myself?

Unless you are a qualified mechanic with the required skills, training and equipment to do the job, we strongly recommend a pcv valve replacement is only carried out by a professional mechanic. ClickMechanic can help get you a vetted and local mechanic to carry out the work. Just enter your postcode and your car's registration number at the top of this page and select the work needed to get an instant fixed price up front.

What is the symptoms of a bad PCV valve?

  • When the 'Engine Oil' warning light is on.
  • When the engine runs at a higher temperature than usual (overheating).
  • When there are leaks underneath the car.
  • When there are leaks / moist patches near the engine.
  • When the engine does not run as smooth as usual.

How long will a pcv valve replacement take?

A pcv valve replacement usually takes around 1 hour, but can take less or more time. Ultimately, the time that the job will take will depend on a number of factors, like your vehicle's make and model, year, as well as other factors. Select your car at the top of this page for information on job time and cost for your vehicle through ClickMechanic.

How often should I replace a pcv valve?

Over time problems can occur with the PCV valve, this is mostly down to poor maintenance. It is therefore advisable that the PCV valve is cleaned or replaced each time the spark plugs or air filter is replaced.

The valve can, for example, get clogged up with oil sludge. Inadequate oil change intervals are a main cause for the valve going faulty. Should this happen, then the engine is at risk of being supplied with too little air, leading to a fuel mixture that is too rich and, potentially, a damaged engine.

Should you experience an issue with the valve, it is advisable to have the PCV valve inspected and, if necessary, have it replaced.

How much does a PCV valve replacement cost?

Prices for a pcv valve replacement range from £75 to £95 with an average cost of £85. Ultimately, the cost of replacing the valve of the positive crankcase ventilation (PCV) system depends on your car and what parts your car's manufacturer recommends using for the replacement. Find out what you could save by having your PCV valve replaced by ClickMechanic by selecting your car at the top of this page!

Can I still drive with a faulty pcv valve?

If you suspect there is any issue with your vehicle's PCV valve (positive crankcase ventilation valve) or there are concerns about its condition, book with a professional mechanic as soon as possible to check and replace the valve if necessary. Driving the vehicle may lead to further complications.

Is a faulty pcv valve an MOT failure?

A faulty PCV valve is not usually checked during an MOT, however, a faulty one may indirectly result in an MOT failure. PCV valves are used to regulate pressure in an engine and a faulty PCV valve can result in too much air entering the cylinders causing the engine to misfire or stall. It is recommended to get it checked and replaced prior to an MOT test.

What happens if you don't replace PCV valve?

If the PCV valve is not replaced if it is faulty, the engine will eventually start to run poorly. Unburned fuel / air mixture is funneled through the PCV back into the engine but over time oil and soot can build up in the PCV valve leading to the part clogging up. The engine may also develop a rough idle.
