Mercedes-Benz PCV Valve Replacement

PCV stands for positive crankcase ventilation. The PCV valve is part of the emissions control system on your Mercedes-Benz and it is also a crankcase ventilation system. It allows the Mercedes-Benz’s engine to ‘breathe’ and removes harmful oil vapours from being released into the atmosphere. The PCV valve regulates the pressure and vapour being released out of the crankcase and moves the vapour into the intake manifold where it blends with the air/fuel mixture and continues through the combustion process.

The valve is situated near or in the top of the Mercedes-Benz’s rocker cover (valve cover). The PCV valve can get stuck open or clogged with sludge and should be inspected regularly and replaced when required. If the PCV valve is failing it can cause your Mercedes-Benz’s engine to run rough and you may notice some exhaust smoke and oil leaks.

One end of the valve is larger than the other, making it almost impossible to fit the valve the wrong way round. Internally the PCV valve closes when your Mercedes-Benz’s engine is off or when there is back pressure. It opens when the engine is idling (low flow) and accelerating (high flow) based on vacuum pressure.

If the PCV valve is left faulty, the extra gunk can foul your Mercedes-Benz’s spark plugs and increase oil consumption. For such an inexpensive item, there really is no excuse for not getting the PCV valve replaced. New spark plugs and replacing burnt oil will cost you much more.
