Oil coming out of a hose by the airfilter

Noticed an oil like wetspot inside the drivers side fender. There's a hose attached at the rear of the stock air filter box and and it goes to the engine block. Looks like it's coming from there. Any idea why and what that hose does?

i believe the other end is connected to your PCV valve. The PCV valve is usually situated on a valve cover, its part of the crankcase ventilation system. Your hose is either cracked or its leaking where it attaches to the airbox, if at the box then maybe put a clamp on it or zip tie it. When your at it you might as well check the PCV valve, which is something you should probably check a couple times a year or every time you chnage your air filter. Pull it out of the valve cover or wherever it is located, you may have to work it back and forth a bit. When you have it out, give it a shake, you should hear a tick tick, if so then it is still good, put it back in. If not you can either try and free it up by spraying some sort of solvent like wd40 or degreaser or mr wrench, or just buy a new one, they are not expensive.

Thanks Kman but I know about the pcv valve and trying the things you mentioned but this hose is just clamped to the back of the air filter box,not into it and it looks like it goes to the lower portion of the engine block...

Are you looking at a breather/vent tube for the front differential?

Hmmm,maybe. Going to have to look closer. It's the only hose attached to the back of the airbox. If it is why is it so wet? Could the front diff be over filled?

as best pointed out, it IS the front diff breather hose....i would check the level asap....
