Help on 08s
 

Hello. I'll try this here. North American mini everyone look but no answers. I've done research and have found two diff things. And both are said to be it. Here it is. I'm looking at an 08 copper s, for 2k. There is oil in the coolent, but not coolent in oil. I've read that it's either head gast or the oil filter gast. Both have been the soliotion. He said that it didn't lose power, but over pressurerised and pushed the oil/coolent out of the tank. Would that be the oil filter gast letting oil in and causing to much fluid? I thought like old school if was head gast then it would lose some power when trying to go?? This will b a 2ed work only car to keep miles off my wrangler.

If you can do a leak down test on it and see if you get bubbles in the coolant. if you do you know that it is a head gasket. if not then it could be a oil cooler.
