Oil (maybe) timing case and injection pump

I will preface this by saying that I don't think I have a real issue here, however I thought I would just make 100% sure I'm not missing something.

So I was replacing my timing belt today on the 300tdi and I noticed that there's some fluid that looks oily seeping in around the three bolts that secure the injection pump to the timing case.
It's not a huge amount, and it looks like it has been in there some time, as there is old looking residue on wall of the case below the pump. There is also a bit of discoloration on the timing cover in the corresponding area.
I can't possibly see were this fluid would be coming from and it's completely dry on the outside of the timing case around the bolts.
Has anyone seen this before? I don't want to miss something before I simply clean it up and bolt everything back together.

**note the really black stuff on the inside of the case is timing belt fuzz**

Should be a seal on the shaft behind the pulley. Could have leaked at one time but if the leak doesn't look active then????

It really looks like the fluid is exclusively coming through the threads, I can't see any oil near the seal area. Could be something old I guess, as you suggest. I'm speculating that either the bolts were lubed up when they were last installed or during an engine cleaning fluid was pushed through the threads... I just can't figure what else would cause it.
