I've been noticing for awhile that after I get home from work, and have parked in the garage, that I can smell the distinct odor of hot oil. Today I jacked up the car and looked under the engine area for any sign of a leak and everything is dry. Even the heat exchanger that the oil filter is screwed onto is dry. The drain plug is dry. The garage floor is dry. I just can't find anything. Since I can't find any actual leaks, I'm not too concerned, but it sure is puzzling. When parked in the open, there's too much air circulation to detect any odor, but it's hard to miss in a closed garage. Has anyone else smelled this???
