EDIT: mechanic suspects rear main seal leaking
Recently bought a an e46 318 (2002) and it's been leaking oil. Looking underneath on the passenger side, I've found whatever this area is totally covered in residue.
Anyone have any idea what I'm looking at?
thanks, and sorry that my first post is a request for help!

This one isn't my car, but it's the area you're looking at from a bit further back (plastic splash guard removed in my pics)
