Oil in air intake: is this a faulty breather valve or by design?

My 2004 Audi a4 is making a gurgling noise from my engine. I am also having to constantly put antifreeze in it. Is this related? I know I'll have to take her to be looked at but can anyone tell me what I am to expect to hear of the issue and cost?
