Based on my experience, That looks like the alternator gasket. If you look up into the engine from the bottom with a good light, you can watch it leak. That looks like used motor oil, right where mine was leaking. It's between an 8 to 10 hour job, & a PITA to do. A 760 would probably be longer. Use some silicone around the o-ring, just to make sure it seals! Ask me how I know!

Good Luck!
