In my engine compartment (3.4L), on the driver's side, about half-way back to the firewall, is a hose that comes up that has a breather-type end on it. It is clamped to the side of the wheel well wall. From that breather-type end, and all the way down the hose, it is all oily & cruddy. What is that thing and is it normal to look like that? I dont have a pic, but I can post one later if needed.

 

got pics already??

 

That sounds like the breather for the front diff. If it's spitting oil, your diff is likely overfilled.

 

there ya go...cool so it is like a safety feature...right?

 

It's a safety feature in that the diff being able to breath protects the seals, but it shouldn't be spitting oil unless it's overfilled or has an air locker with a bad o-ring.
