Finding a leak can be difficult because it can ve blown back from the point where it is leaking. The best thing to do is to clean the engine thouroughly with brake cleaner. Then see if you can follow the path from where it is puddlling under the car to the car and trace its path. You could have a bad main seal if the oil is coming from the end of the oil pan.
