Hello folks I am trying to narrow down the possible culprits leading to random misfiring. The fuel tank breather valve is one of the last few things that I can tackle before taking it to a shop again. I can't seem to find it in the engine bay, with or without my glasses on. I can almost squeeze my head in between the engine and firewall. Pictures below show the area that I have access to, with the air box and pipes out. Any guidance is appreciated!
Thank you so much for the pics and link! It was already a pain to locate it. Let's see how far I can go now that I have a mental picture of what's going on back there...

Reason: typo
I was only able to loosen up the 10 mm bolt and bracket from the top. The valve was out of sight and difficult to grab. Since I rented a lift for an afternoon, the shop owner helped me replace it by working from under the car (on the lift). It was easier to see and access from under. 😂 It wasn't the culprit of my problems though. Car ran the same on my way home. Next week I will replace the valve cover gasket.
All the spark plugs had oil on them so the tube seals are definitely out. I hope a new valve cover gasket will fix it. It doesn't run rough until a few miles after getting up to temp, and only when the rev is down below 2K.
