It's probably coming from the valve covers. Can you give a bettter description, like the general area that the oil is coming from and how much oil is leaking out? It's a good idea the check your oil level weekly, leak or no leak.

I would clean up the front of the engine with a powerwash/degreaser and see where the leak is. Could be KDP problem.

if it was on the drivers side i would say check the vacuum pump, I had a pretty good leak there. Can you take some pictures after you power wash it and drive it for a day or two?
