Oil can climb up the passage and actually dump out of the lower fitting.
This is a good reason to always use the top fitting as a rule of thumb.

In the past I've followed this rule of thumb but after last years experience on the street, I changed my setup a little this time around. Even on the street now, I would say cap the lower fitting. I was filling my ~pt container every few hundred miles with blowby nastiness. I thought it was creeping up the oil filter which is why I built a little funnel type device inside the filler to prevent this from happening. It didn't make a shit of difference which tells me it's coming from the nipple on the int iron. New setup has this capped.
