2004 DS oil leak

[1arunem]

Ok, so I got my buddies DS running again (wiring issues). He had also asked me to see if I could tell where the oil leak was coming from.

Well, looks like I found it but not sure exactly what may be leaking?

If you look at the pictures, it appears to be coming from around the base of the head, where the case/case cover meet. If I look between the metal shroud and the head fins, I can see oil coming out but oddly can also see rotation as if maybe there is a piece of the case cover or case missing/broken and I am seeing the internals rotate. It is very small. Make sense?

Case cover gasket maybe? Coming from below head?

Note the screwdriver tip in the picture is approximately where the leak appears to be. This is just to the right/above the pulse line and oil fill tube. It is running down from just above where the screwdriver tip is and below head fin.

Thanks for any input!

P.S. the area is very clean as I sprayed it with brake cleaner to find the leak. It was very oily and grimy beforehand.
