My '90 300SE has an oil leak. Last week I was under the car and noticed the oil looked as though it was coming from what looked like a rubber hose that attatched to a pump like thing located above the alternator.

What is the pump thingie and is this hose a probable area for an oil leak? I tried to take it to my tech, but they are a man short and can't get to it.

I'd appreciate any help.
