Oil leak on 87K 75

[48882]

There are two oil conditions I see in this photo. One is the oil coming out where the wires are. I believe this is telling me that the oil pump seal is wearing out (bike has 120k miles).

The one I am more curious about is the oil around the bolt in the upper right. See green highlight. What do you think I can do about that?

How do I fix this kind of oil leak? Don't look at the oil filter cover.. I fixed that problem already. This one is the hex bolt up in the corner at the same level as the manifold bolts behind the water pump. I cleaned it up after these photos and it's dripping fresh oil. Thanks in advance.

The usual approach is to thoroughly clean the area and then go for a ride. Come back and blow some baby powder around to get a clearer view as to exactly where the oil is originating.

The pump should be rebuilt, but after everything is cleaned up you may find that that's the only problem. The oil on that bolt could very plausibly be blowing back from the pump assembly.
