Narrative:

Departing runway 25L at cpm, oil started blowing back over the cowling and onto my windshield. I realized that I had left the oil filler cap off after adding oil to the engine. I didn't think I had enough runway to abort takeoff, so I made a coordinated teardrop return to runway 7R while announcing my intentions. However, an aircraft on final to runway 25L had not realized my broadcast and did not abort his landing until he saw me. I diverted to runway 7L and completed my landing, however, with less runway. I don't know of any violation in my flying technique except that the airplane was not completely ready for flight. It was a very good lesson but not one that I care to practice. While adding oil to the engine my new bride was distracting me with many questions regarding the airplane. The oil filler cap has since been added to my preflight checklist.
