I have 2004 Durango 4.7. Under the air filter assembly box there is a part with tubes coming out of it, the part is leaking oil. I have search the web, the auto parts store web sites, bought book on the truck. It's like this part doesnt exist. It's not on any diagram or photo of the engine.

Does anyone know what it is? I am guessing the oil pressure sending unit, but when search I can only find the oil pressure switch.

If you unbolt the air filter box and remove it from the Durango, the mystery Part is right under it, it is about 2in round about 4 to 6 inches long. It has 3 tubes coming out. The top if the part is leaking the oil, its not one of the hoses.
