[Closed] Fork noises. Reason to worry?

I've got a Reba Dual Air. Last night, it entertained me to a new sensation. I know they are quite noisy, they do usually make squishing noises during compression and rebound. Last night though, it was definitely sounding like air is being pushed out from round about the compression damping knob, or floodgate cap during compression.
Anyone had this before?

Along with this, there did seem to evidence of a slight fluid leak from under the compression knob, which I assume would indicate a seal having gone somewhere in the compression damping circuit.

I've serviced the lowers a few times, but never opened up the upper legs. I'm hoping this will be an easy and inexpensive fix!
