Well, without seeing any pictures of this cannister and the fact that you say it is on the passenger side valve cover, I would have to say it is probably a breather assembly for the crankcase.

I'm guessing you're talking about the diverter valve for the air pump. It's a black cube-like box on the passenger side, next to the valve cover. So it's for emissions if that's what you're talking about.
