there is s vent kit to be added on, and an updated VCV if it is in fact a VCV issue. Also, check the cannister for mud build up inside. If you replace the valve again (which should definately have the oring) without looking at the cannister, it'll just keep failing. It's one bolt to take it out, but you may have to drop the spare first.
I'd check the valve as described in the above post before replacing. The new (updated) style as of a couple years ago has more of a metal body. I've also just recently seen a rash of evap hoses collapsed. First time in all my years with Nissan.
