Oil leak

[kat-a-tonik]

I recently replaced all the seals and O-rings in the lower unit of my FD-20C 1966 20hp Johnson, I pressure checked it and found no leaks, I took out on the water a couple of times and checked and there wasn't any water in the oil, and now a couple of weeks later I was getting it ready to hit the water again and noticed I minute amount of gear oil the bottom of the lower unit, upon further inspection I noticed it was coming from a hole on the left side of the lower unit ( im guessing this is some kind of weep hole ) so I guess I'm going to have to tear back into it, any Ideas of what I might have done wrong

Above the cav plate,or above the water pump on the exaust housing?

Below cavitation plate, just slightly above the prop

I looked it over again this morning and this afternoon and there wasn't any more oil on it

No Title

Ok guys I have a mystery on my hands, as stated I recently I replaced the seals in this lower unit and am seeing oil seepage coming from the small hole in the picture, its not much it takes a couple of weeks of sitting for it to even have enough to drip off of the bottom of the gear case.
I have had it out on the water a lot and no water is showing in the gear oil.
I did a pressure test on the unit and there is air leaking from this hole and nothing from any of the seals.
I tried probing the hole with a fine piece of copper wire but couldn't get the wire to go only about 1/16 of an inch into the hole, I even tried to shine a light into it and couldn't see the light anywhere in the lower unit.
Does anyone have any Ideas about what is going on.
