I'm not sure if this warrants starting a new thread... it's too simple.
When you place the cap on the tank, that tight seal pushes extra air into the tank, pushing the liquid into the atomizer area... this causes yucky leaks. And after vaping a bit, that tight seal creates a bit of a vacuum that keeps liquid from going into the atomizer. The solution? You need to allow air into the tank... and of course, the Vortex was designed so you could carry it without leaking...
First, remove the silicone seal... and invert the outside edge because you'll only need to cut a bit from the inside. What you're doing is creating a small vent that leads from the mouthpiece into the tank. Air doesn't need a lot of space to move, so probably the smaller, the better. I used a razor at first and finished with nail clippers. The silicone seal still fits quite well.
Unfortunately, there is a side-effect. Condensation from the mouthpiece no longer drips into the center tube... it drips into the tank itself. Actually, this isn't so bad... it's just water and burns up without any problem. But it does make the juice a bit diluted as you reach the end of the tank. Actually, I noticed a noticed an improvement in flavor. Heh. This also means you'll have to be careful when carrying tanks around. If it's upside-down, some liquid may escape through that vent. As I said, a smaller vent is probably better. Especially when the liquid starts to get diluted... but if it's thick, I doubt more than a few drops will escape, if any.
Anybody else want to try this?

After inverting the silcone seal, it should look like this. The red line indicates where I cut with a razor (twice). The diamond indicates where I cut a small chunk out.

The result... my two razor lines became triangle-shaped. Not sure what is the best shape here. Possibly two straight lines are better but the triangle acts as a kind of funnel. Take a close look near the bottom and note the tiny chuck missing... that seems to be the most important. I think I cut too much out. If you cut too little, though, the condensation will drip back into the center tube... so it's better to cut a bit, test it out, then cut some more if you're not satisfied.

I left it out last night, confident... but it leaked the last 1/2mL all through the connector. On the other hand, I've been using the same cap with a different cart all day and only a tiny leak. I'm guessing it still leaks a bit, but continual use sucks the leak back up into the atomizer.
So, it's great for daytime vaping... not so good to leave out overnight. I've only tested this on one cap with two carts. I'm very happy with the results, even if it still means having to leave it empty when not in use.
I have some suspicion that the bottom connector may be responsible for the overnight leak. Tightening it up and then adjusting the 901->eGo adapter might help.
Now, I just wish I would stop burning my lips on the hot mouthpiece. Maybe if I stopped enjoying the amazing flavor so much...
