Ahh, so what they're saying is, the o-rings on the ARB failed, and let the oil slide into the unit, and right out the air line. In other words, pretty much the only failure that could happen to the unit, did happen...

that suxs, but at least it's covered under warranty. ARB has the occasional problem with their o-rings; usually it's installer error, though, 'cause if they get pinched, scraped, damaged, etc., when putting them on, then they'll fail pretty easily.

Oh well. hopefully it'll take care of the problem for good. Just make sure your installer doesn't "roll" the o-rings on...that's probably what caused 'em to fail in the first place.
