I checked the problem area again today and the fluid is black and very sticky. It seems like it has been there for a while. I've got an appointment for next week. I still have no idea where it is from. Hopefully when I take it in, there will be nothing but good news. Or at least a cheap fix. For the record, I used sea foam for the first time in the crankcase recently.
