So I pulled out my Oly 7-14mm this am and the hood was wiggling and heard something loose inside. Grrrrr. Figured I broke something plastic inside that hold the hood on. And little investigation reveals 3 metal screws that hold the hood in place. One was out and the others were loose. Quick tighten and test and all fixed. Must remove the snap ring around front element carefully to reveal said screws. Here is a photo with screws highlighted: Hope this helps someone else in the future.
