Little late, but for the record (and your sanity) there are two different coils and trying to swap them can produce "less than good" results like leaking, gurgling and battery contact issues.
There is one head for the PT's, PT Mini's and EVOD and a different head for the T3s/MT3s. The diameter of that large metal washer right below the wick is a different size and the corresponding fitting on the base it fits is different. You can see the difference if you put the two different coils side by side.
Put a T3s coil in a PT/EVOD base and the metal washer is too small for the opening in the base, which can result in leaking and gurgling problems.
Put a PT/EVOD coil in a T3s base and the washer is too large, riding on top of the opening it's supposed to fit down into, resulting in the same potential problems in addition to lack of contact issues with the battery center post.
