Narrative:
I did a walk around; finding no anomalies. We then flew to ZZZ; and upon my between flights walk around; I noticed that the forward underside of the #2 nacelle was dripping engine oil. I notified the captain immediately and a write up followed. Contract maintenance arrived and spent about an hour cleaning all excess oil inside and outside of the nacelle. We then did a runup for about 5 minutes to find further leaking at the direction of maintenance; but none was found. The aircraft was signed off and we boarded and departed. Curious to see if the leak had truly stopped; I engaged the autopilot at 10;000 ft and looked out my window at the #2 engine. I immediately noticed that oil was indeed streaming out of the oil service door; the larger gull door; and various other seams in the inboard side of the nacelle. I told the captain; and he had a look as well. We both agreed that a great deal of oil would have to be leaking for us to see continuous streams of it as we did; so he contacted our dispatcher. After a brief discussion; maintenance control and our dispatcher advised that we discontinue the flight and land as soon as possible. ATC advised gave us a direct clearance; and we descended to a normal landing. I can only speculate that this occurred because the #2 engine was over serviced with oil; and/or it had a leak.
