I do not think it was left over because A) they said they cleaned the oil around the area so I could not smell the oil anymore (Unlikely they did though), and B) the drop was right next to (Less than 1 inch) from the seal/banjo fitting they said they replaced. Very hard to work on that area without even accidently touching the drip.
I know the drip is not much, but if it coats the area again by the time I need to leave for the track, I really need to give it some thought.
