No not the song.....

I was checking my engine yesterday...just listening and looking things over. I noticed small bubbles going into the degas bottle. Nothing major but they were constant. I have researched and noticed this could be the symptom for a bad head gasket or oil cooler. My question: Is a small amount of bubbling normal or should there be absolutely no bubbles feeding back to the degas bottle?? Many Thanks.

Could the bubbles be a result of cavitation?
