Mine was making this same noise. It's coming from the passenger side PCV. I don't think this is anything to be concerned about.

Mine does the exact same thing but I also have a knocking/clicking sound.
I only hear it when the engine is warmed up and idles at .6 RPM.
Not sure what that clicking sound is.
It just started noticing it at around 10k miles
Anyone have this sound too?
