Gap?

Gasket looks fine. Does it leak smoke? If so check out some YouTube videos and they show you how to make it right.

Yes, it is leaking smoke when the other vents are closed or smoking a lot.
I'll check YouTube 

Your planes are out of whack and a leaking gasket will mean premature aging/failure of even a Nomex gasket. Not sure what YT videos you will be watching, but I might be able to give you some simpler solution ideas.

Just FYI, the bands can commonly move around do to use and expansion and contraction of dissimilar materials. I say this so you aren't too hard on your dealer. All you need to do is loosen the bands and have someone push the lid down until tight, then tighten the lower band first followed by the upper. Fixed. Little adjustments like this are not uncommon.  Good luck!

It still looks like all you need to do is loosen the hinges on both sides where they attach to the upper and lower bands, straighten them out and retighten and it should drop into place.  

thats a common problem many of us had: overbite  (or underbite).  Glad you got the dealer to come out and adjust it.  Wish I had thought of that!!!

Remember to check the tightness of those bolts also. It does not look like they are tight enough(bent) in those pictures. Might just be the angle of the camera. Better safer than sorry.
