Most likely the engine is worn out. Combustion gasses will leak past worn piston rings ( blow-by) into the crankcase. The hose is the PCV (Positive Crankcase Ventilation) hose and is designed to vent a certain amount of these gasses back through the engine. Sounds like there's just too much leakage for the system to handle now.
AnswerA small amount of oil leaking back up the tube isn't abnormal, but if you have a considerable amount, make sure the PVC valve and hose are completely clear and working properly.pcv is bad.

These are breather tubes. On older models there is usually a breather filter in its place. On newer cars the engineers removed this filter by placing a hose connected to the air duct. (Since this air is already filtered)
It's on the firewall. It is a can, which normally is black, with two fuel hoses coming out the top of it.
