Chrysler Sebring leaking oil from somewhere.

oil in the antifreeze or vice verses would indicate a blown head gasket but have you checked to make sure the oil drain plug is in tight and the oil filter is on if they are put a piece of cardboard under it to see where it is dripping from and see if you can trace it

The oil isn't leaking from under the car it's leaking onto the silver piece under the hood of the car

Valve seal probs. That's what happened to mine.
