How long will a pcv valve replacement take on my Mercedes-Benz?

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 my Mercedes-Benz 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 on Mercedes-Benz 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.
