The best way to find your leak would probably be to go to you local autoparts store ask the for some oil leak detection dye pour the bottle of die down your oil fill tube and start you car let it run at idle for a few minutes then shut it off wait for an hour or so and then go underneath your car with a black light the dye should show up underneath the blacklight then all you have to do is trace the dye with the blacklight back to your leak. Hopefully this helps you oil leaks can be hard to find sometimes.
