Oil Where It Doesnt Belong?

In the process of pulling my transmission, because it needs a new mount, slave cylinder(old nuts are stripped), and need to run a new clutch line. Got the first two bolts that go through to the block off, and the threads on both were covered in oil, with the lower bolt being really milky, like so:

IS this anything to worry about? I'm guessing (hoping) that its just oil that leaked into the bolt hole when my distributor was leaking, but want to make sure its nothing important before putting them back in.

Possibly leaking oil and leaking freeze plug in the back of the engine? Looks pretty mixed up though like contaminated crankcase oil.

Hasn't leaked any for months, since I replaced the distributor o-ring. That was the lowest transmission bolt on the drivers side. The next one up looked like it was just dipped in old oil, not milky or foamy like the picture.

Slow valve cover leak? And as u drive in rain there's ur water on ur lower bolt?

I'm assuming its just water from all the recent rain. May have a slow leak..not sure, Something i'll have to check out tomorrow.

It's good practice to oil fasteners before assembly to ensure both proper torque when tightening and that the fastener will come apart without twisting off the next time it is removed. Maybe the last time it was assembled the mechanic used plenty of lube.

Any  drop of water finding  its way in would emulsify with any oil already in there,  turning it milky - think of how much vibration the engine makes.

I wouldn't be concerned - those are blind holes into the block, right? Look at their  location and direction - if you drilled farther, what would their path intersect, and how far would you have to drill to get there? I don't think you need to worry.
