I would say not to worry about it, I have not done this with my X..but I have done it once along time ago with a toyota pickup.... I just used some engine degreaser and washed the engine compartment really well...(minding the electrical connections as best you can..). as long as you fill your oil to the appropriate level everything will be fine, and you will probably get that smell for awhile, until it burns itself off... I wouldn't worry, good thing you caught it when you did!! Prost!
