Conclusion:
Install an O-ring on the coil, resting in the two slots.
Scope:
Just bought an innokin T20-S recently. Mine was leaking liquid (50/50) out of the tank through the air intakes. Like many other buyers have already experienced (and not because of wrong installation of the coil) the device is leaking heavily trough the air intake holes. As a mechanical engineer, I have been experimenting and found a solution to the problem that I want to share.
Why is it leaking?:
It leakes because of gravity forcing the fluid to pass through the cotton, down the coil and out of the air intake holes.
Solution: Install an O-ring on the coil (0.8W), resting in between the two slots. I've used an NBR 70 1.6 x 10 mm O-ring. With this size O-ring there is still room for air to be sucked past the coil, but the capillary forces will prevent the liquid to pass. The restriction has actually been a benefit for myself, because it gives a bit tighter draw, it's really good actually. You can try out different sizes O-rings, but this one worked out really well. That is what that has to be given.
