I found it inside my engine. There are three things hooked up to it: electrical wires, a tube facing the front of the car, and a tube facing the rear of the car. The valve is somehow attached to a metal bracket too, and the metal bracket is held on by a single bolt. I can remove the electrical wires and the tube facing the front of the car, but the tube facing the back is stubborn. Does anyone know how to remove it properly? This particular tube is L shaped and has a couple of white things on it. Also how do I remove the whole valve from the metal bracket it's on? Do I have to unbolt the whole bracket to make it easier?

 

Yeah just unbolt it that way it's a lot easier.
