  Q: How do you remove and replace the PCV valve in your Nissan Altima?

  A: This valve is situated on the valve cover with the aid of the hose already connected to the valve, therefore you have to first disconnect the hose and then take out the PCV valve. I prefer doing this with the engine in idle after the engine has warmed up, with your fingers, apply pressure near one end of the valve then, if there is no vacuum, look for a plugged hose or the valve then replace it if it is plugged or deteriorated. When buying a new PCV valve, make sure that you buy the right one for your car and engine capacity as you hold it alongside the old valve. If removal is done in a sequential manner, installation on the other hand is done in a sequential backward manner.
