So I am resealing the oil pan on a 2012 Mini S and I discover this in the bottom as I emptied the remaining oil. Can anyone elucidate what it is and where it may have come from? The outside is aluminum but the pressed in piece is steel. Looks like a plug of sorts but can't seem to locate its origin.

I have determined that it is a coolant plug that is located in the head....(that explains the oil water mix lol!)

 

Yikes, thats not what you want to find, did you get it fixed.

 

I did but it was a complete mess - btw water and oil does mix LOL. Car back on the road and running great!

 

lol, Glad its ok now, if i saw that in the pan my heart would drop.
