Has anyone noticed there to be steam in the engine oil fill hole or dipstick tube after the car has been running for a while and is hot? I've never seen this before, just wondering if it is unusual or not, or any kind of indication of a problem. It doesn't billow out or anything and it's not exhaust fumes (car was off when I checked). Just kind of sifts around. I can blow it out and it kind of creeps back up. Thoughts? I can post pictures later if need be. Hopefully it's normal
