Need Hose for valve cover

[bareddread]

The hose that comes off of my valve cover and connects to my air intake is occasionally slipping off, I've secured it with clamps. I've been unable to find the part online for replacement so I was wondering if anyone knows what the part name/ part number is? Could this be the cause of an oil leak?

Crankcase breather vent tube. Should be the same 4.0L SOHC configuration and parts as 2001 (Job 2) thru 2005 Sport Tracs and 2001-03 Sports. Some have deleted the tube using a small filter on the valve cover and plugged the hole in the rubber intake tube. Don't see why hose clamps wouldn't seal either end. Fittings or plastic breather tube leaking? There's several threads for the breather tube bypass, do a search.

Thank you so much for the reply! I don't really believe that it's leaking pressure anymore but i'm going to go ahead and replace it anyways.
