Hrm, that's your oil cooler seals.
Check out your oil, make sure it's not looking like chocolate milk. If it is, drain it out. It will corrode the inside of your engine.
Don't drive it until the cooler seals are done (Except maybe to the shop if you aren't doing them).
If your oil is clean, then you are lucky so far. You'll be alright if you change the oil cooler seals.
