Oil separator - Catch can - Con can ???
 

So I only found one post regarding this and it was from last October.
I have a 2015 3.5 EB and would like to know the latest greatest on the need for a catch can. I understand that the 2015 3.5 EB motors do not have port injection, only direct, so that the valves get dirty over time. More recent EB's have direct and port injection apparently, and do not need the catch can (as much).
