need to repair oil leakage and Oil boiling in the engine?

What is your question?

I have repaired the Radiator new, but did not fix the problem I have Oil leak some where on the engine, my guess it is where the line coming from the radiator to the engine

What makes this problem better or worse?

when the engine gets hot Worse

How long has your 2007 Kia Rondo had this problem?

since I bought the car noticed it using Oil , few months
