Oil leak...cant find it

My car has been parked in my garage for the past week (auto detailed). Before any of my work was done there was an oil leak dripping down from the oil pan. Again, after all my work, there is still a leak and when looking under the car I see oil on the bottom of the pan. It is coming from somewhere above. Any ideas? Car has 132K miles.
