I trust that the guides were revised at some point, it's just weird that the facts are so inconsistent.
Maybe what you said is the answer though: the newer plastics implemented in the new guides stain less easily and appear lighter in color (EDIT: or they're just newer so less stained regardless of plastic used
) ? Like the video in the first page of this thread shows, even the old guides were white at production.
Still confused that the revision date is 01/2015 though. Like I said, at that point we were only months away from the LCI hitting dealerships, so why even bother revising the N20 so majorly for a couple months of production.
The whole timing chain issue is just a crap shoot.
