Help! TFV4 R3 leaking!

[1SuperNova1]

hi all, i'm new here and was hoping i could get some advice on what the hell is going on with this coil head.
i've had pretty much no issue with the tfv4 leaking wise until now... i've been using the R3 rebuildable coil head from the beast kit and it's pissing it everywhere.
the only reason i can think is because the coils are too low down to the air holes, but i simply can't believe that that much juice leaks from the wicking.
this is the first coil:

the second:

and the third:

i will try making the coils more compact so no liquid can leak through the holes in between and report back. thanks in advance-
Joe

ok so i've replaced the top o ring with a thicker one, and i've squashed the coils together and upwards. i have a completely full tank now and i'm experiencing no leakage. i'll keep everyone posted because i'm aware this might be an issue other people have too

Sometimes the wicking has a lot to do with it. Not enough cotton or too much cotton. Play around. It will come together
