Just today, however, I checked the coolant (under radiator cap) and noticed a lot of oil sludge in there... this looks like really bad news. What does this sound like to you? I'm considering selling it because this sounds like a headache of a head gasket(?) job.
Please let me know what you think it could be, or what you would do if you were me. The car is in otherwise great shape!
