Gasket Problem?

[elemgee]

When changing the oil in my 96 SVX, I noticed something leaking at the bottom of the ....thats my question, I don't know what part this is. As you face the front of the engine, its that black plastic cover thats on the left, immediately in back (towards the firewall, about 2 inches behind the radiator) of the radiator. It extends from the top of the engine, to the bottom. A similar type of cover is on the right hand side which i think is the cover for the timing belt.

Anyway, at the bottom of this plastic thing (you only see the bottom of it with the plastic shroud removed from under the car to get to the oil filter) part of a rubber gasket is visible, and its leaking something.

Sorry for the very unclear description. Hopefully someone will read this and think "hey, I had that exact same problem and its the ________ (fill in part here)". Thanks.
