Some may find this helpful. I picked up a couple Evods, a Protank II and a Unitank recently. Trying out different tank setups. I had the "leaking" issues through the head that others have mentioned. I tried the double o-ring/cap method on the coils to fix the leaks, etc.
One big thing I noticed. The Evod heads, which did not leak had a slightly different seal material than the heads that came with the PT and the UT. I swapped out the UT and PT heads for Evod ones and no more leaking/flooding through the head anymore.
