The oil pan sealing flange and the block are machined aluminum (or iron). The gasket supplied is coated with graphite, and I don't think that any sealant is needed, assuming that those machined surfaces haven't been damaged.
I would not ever get RTV anywhere NEAR a 116/117 engine. I found bits of definitely non-MB RTV in the oiling tubes for the cam bearings of my 380 engine. Keep in mind that all the oil in the entire engine goes through those tiny holes in those tubes and if even ONE gets plugged, you will have big troubles. I did.
People have said that it's very difficult to get the intake manifold sealed without RTV, and yet, others have done it with old -school sticky "gasket dressing" or "gaskacinch". After this experience, I'm going with the gaskacinch.
