So I recently installed an OCC from ADD-W1, and I've put almost 1000 miles on it so far and have been checking it periodically, but it's been completely empty every time I've checked so far, not a single drop of anything. I've looked around and as far as I can tell, all my hose and everything is solid, no leaks or anything. So I suppose my real question is, is it possible that my virtually brand new car just doesn't really have a need for an OCC because it isn't hardly producing any of the crap it's supposed to catch? Or is it more likely that I screwed up something with the installation? Any insight is appreciated.
