Hello,

I have a 2005 Tribute V6. There is a line that runs between the air filter housing area, up to the front of the engine near the radiator, and down into the front of the engine. The end that goes to the front of the engine has come out. It looks like it should snap back in but doesn't. It sits in the opening but isn't secure. Can anyone tell me what this part is, what it does, and how critical it is to get this looked at quickly. Thank you.

 

Photos will help alot.

 

Here is one end of the line, near the center of the photo:


Here is the other end where it runs down to the front of the engine, behind the radiator:





The bottom end is what is loose.

 

PCV system I think.

 

It is a PCV Breather.
It comes from the front valve cover and from the back valve cover , them it connects to the intake hose.
