Regarding seepage from air vents, if you check my earlier posts you'll see I've been struggling with this issue for some time. So many possible causes, it's hard to pin down.
I have 3 K5s. I've replaced every o-ring, including the big ones at top & bottom of tank body, and modified my wicking. 2 of my 3 K5s are now virtually free of any seepage from air vents (and yes, it's seepage, NOT condensation) yet one of them still seeps no matter what I do.
I think there may be some validity to keeping the wick away from the air hole, but the "add more cotton" theory has proven to be B.S. Big, fat juicy wicks are actually more likely to seep. Quorax has a video showing how he wicks his K5s, which is the model I use now.
