Oil Leak from Under Front Driver Tire

[haydenswitzer]

I had my car (2005 X5 3.0i, 150k miles) running in my driveway for a few hours while detailing my car today and as I was finishing up I noticed a pool of oil under the front driver tire. It looks like its coming out of a drill hole in the back of the wheel well as you can see in the picture here



Here is the pool under my car



The oil does not leak from my car if it is off, only while it is running. If you guys have any knowledge on where the oil may be originating from please let me know! Thanks.
