1993 BMW 325is Q&A

1993 BMW 325is Question: When oil added to radiator, oil rose to top? no leaks,no white exhaust,runs well

What else could be problem other than blown head gasket? What could be leaking oil into cooling system? No milky substance on dip stick......Thought belt was loose or water pump faulty because of a funny noise? Hoping it's not head gasket! Need some luck? -
Answer 1
Does your radiator have an engine oil cooler in it? If it does , that could be leaking into radiator.Have you monitored your oil level at all , since noticing this? -
