NEED HELP!

I was goign over a few things before my Tellico trip and I checked out my front ARB and when I disengaged the locker it did not sound like its normal clearing of the air. Turns out, the compressor is shooting out gear oil too. I know this means I have a leak in the line or maybe a failed seal but I was wondering if this had happened to anyone else. Any info would be great, the more I know exactly what to look for the faster things will go and be ready by this weekend. Thanks.
