I'm sure the solution to my problem is in the links above, but I'm too new to fixing my car to know the proper terminology. I may even be in the wrong thread. In any case, here's my problem.

I just bought a 1982 300TD and noticed oil leaking after I parked it. After poking around a little, it looks like there's an oil overflow hose that comes out of the top of the engine and goes into the air filter compartment. There's some kind of metal device inside the air filter compartment that the hose dumps into. The leak is somewhere in there, having spread motor oil throughout the air filter compartment and onto the air filter itself.

What is the proper name of the hose that goes from the engine into the air filter compartment if I need to buy a replacement? What is the metal device in the air filter compartment called and what does it do?

Blow-by tube and the device inside the air filter is the oil separator. Look under the air filter and there is a metal tube the filter housing sets into. That drains the separated oil back to the oil pan and it often does not get put back in right which makes an oil mess in the engine compartment.
