Hi, I am the one that started this thread and my 'leak' is completely gone. After much testing with the blacklight (see my posts above) it seems that the leaking was actually coming out of the dipstick. If you overfill the car (even slightly), or don't push the dipstick in completely, you will get a slight leak. I would suggest that you get the dealer to put the reflective stuff in your oil and get a blacklight (it works really well).
