Oil leaking out of my exhaust

I have a 2010 328i with oil leaking out of the exhaust. Does anyone know what that could be?

Motor oil from your exhaust pipe? Not just condensation combined with a bunch of exhaust soot?

If not condensation, are you using lots and lots of oil?

Yes I am. It's definitely oil and not condensation. It has overheated for a few seconds before any of this happening.

Important word there - overheated! Please explain circumstances further.
Any misfires, running rough or codes?
You could have a blown headgasket, cracked head or just oil dripping in from a spark plug (valve cover gasket issue) or the CCV. Can you see if the coolant and oil are mixing?

+1, we need more information on this "overheated" situation.

Head gasket was what my mind went to first when you said "overheated". But again, need a lot more info.

The car said I was overheating as I turned into my neighborhood from a broken hose. I change the hose and changed the oil. There was no coolant in the oil. I checked the valve cover gasket and as I did that I found oil on the threads of the spark plugs.

Well now that you know where the oil is coming from...if the temp hit the red even for a second I'd be preparing to at least do a compression & leak down test.
