This is unusual. I changed my gear oil a few weeks back and noticed a leak dripping from the skidplate. I figured the drain plug worked loose so I took the skid off and there is oil coming out of a hole in the center. Its almost like a weep hole or something. The hole is not threaded and I can see shiny steel if I look in with a flashlight. Can anyone tell me whats going on here or identify what it is. The leak is very slow but im afraid to let my girl drive it cuz I dont want smegma getting in there.

Here is a pic but keep in mind I stuck a small rubber plug in there to stop the leak.
The hole is just to the left of the drain plug.
