Thanks! If you are talking about the pcv valve that's in the left side of the block (one way valve for the breather system) I didn't exactly do much with it. I just checked it's working had a bit of a clean and jammed a piece of hose in (I happened to have hose that's the correct diameter). The hose is just pointed to the underside of the car so the fumes don't go all over messing the engine bay.
