TFV8 leakage (UPDATED)

Member For 4 Years
Ok so I recently got a smok alien and TFV8. Literally had it for a day and dropped the mod out of my pocket.

To my surprise the tank did not shatter. However the base popped off a bit due to the quad coil atomizer being crooked from the fall. Needless to say the coil was ruined.

When I dissembled everything I had to grab two vice grips to unscrew the coil from the base as it was sitting crooked and could not be undone with your fingers.

Since the coil was destroyed I decided to use the spare disposable that came with it. I cleaned up the tank, placed the new coil in and everything went together flush and perfect.

This is where my troubles started. For whatever reason I'm getting tiny leakage that is coming through the air slots. Every time I disassemble I find a bit of juice sitting in the base. So I clean and reinstall everything.

I decided to watch some YouTube clips and noticed a number of people complaining about leakage from the factory coils. This has to do with the black rubber o ring not sitting completely flush with the coil. Since the ground wires have to stick out a little.

My issue is this, prior to the drop the quad coil had no leakage, so I'm starting wonder is this a case by case incident depending on the coils or did I F¥€£ this thing up and need to buy a new tank? Do you guys have minor leakage that comes through the air vents and is this normal???

Are you certain it is juice or is it just condensation from the vapor?

I know my tanks will usually have a condensation that appears after vaping on that tank for a while. However, there are discussion threads about the manufactured coils having leak issues. This is 99.9% of the time due to the o'rings not seating correctly.

There are also issues with the RBA head (mine) that allow leaking. This however is due to the wicking method / amount of wick being setup in the coil. I'm still working on the exact amount to use in the RBA head to fix the "leaking" issue.

Seeing as you dropped it... you could also have a threading issue now and it is causing juice to weep and the o'ring not to seal correctly on the coil to base.

Here is one recent issue with the baby beast tank and o'rings -- http://vapingunderground.com/threads/big-baby-beast-help-needed.299156/

Thanks for the quick response phantom. I'm pretty sure it's juice as the consistency is the same and it's sticky like the juice I'm vaping.

I took a look at the coil and this could definitely doesn't sit flush. But one would think that if it's screwed down the o ring should seal. Then again when the juice gets hot enough the viscosity of it is quite thin allowing it to leak more easily.

I too am wondering if it's a threading issue but I am able to thread these new coils as easily as I was prior to the drop and the coil to my naked eye seems like it's fairly straight.

You think iits worth it to buy a new tank to test out?

How about the top o'ring and threading ... is it sealing correctly? Not only the bottom can cause the juice to flow out.
And yes, the viscosity on the juice is very thin when you really heat it up. And these coils will heat it up quickly.

:) Only you can answer that one. I know I love both of my BB tanks and my Big BB tank. I use the RBA however and not the manufactured coils.

Now that you bring it up it very well might be a leak from the top cap o ring. I'm vaping pretty heavy right now and my juice level is below the o ring and I have not seen any juice leak. Also every time I fill it seems like some juice leaks out.

Looking at the top cap with my naked eye it seems like it's flush but the drop could have done a. It or damage. You think I should swap out the o ring?

I would check the threading on the top cap and see if you can tell if there is any bent/messed up threads. And yes, I would try replacing the o'ring as well. I wouldn't throw away the old one, just in case it is not bad or damaged.

If replacing the o'ring does fix it, then there could be a split in the other one that was removed.

Just top filled and am noticing some slight leakage from one of the vents. I'm almost positive you're bang on with your diagnosis.

Once I drain the tank I'm gonna swap the ring. Thanks for all the help my friend!

Not a problem.

Yup, sure does.

Well quick update. Changed the o ring but I'm still getting a bit of leakage. Not as much as before but a tiny bit.

Talked with a buddy of mine who is running the same set up and all he uses is disposable coils. He mentioned it's pretty common for him too. Not sure if buying a new tank will fix this. Might just have to live with it

Well ... I have only used two of the disposable coils that came with by BB tanks (was curious how they tasted) and neither of them have leaked yet. However, I do primarily use my RBA coils with these tanks as I didn't want to get "hooked" on using the disposable coils. I prefer to build my own coils and save money.

Sounds like the fall bent something too far out of tolerance for the o-rings to seal. Might be time for a new tank.

most of the time when my tank leaks its because its not screwed on tight, check the o rings. once i did this i was leak free

Thanks for the tip Dbro! I think it's screwed down pretty tight.

I'm gonna try to post a pic of the leakage when it happens

try screwing the coil to the top cap first, nice and tight then the bottom, its not the proper way to install but doing so makes the coil tight to the o ring. worked for me

Very interesting! Ok gonna give it a shot on the next fill up.

Here is a pic of how the leakage looks. As you can see it's minor juice that sits in the air slots

if it leaks when you fill it to the top then its the top cap o ring if not then it could be the coil it self.

At first I was having issues when I was top filling. Then took phantoms advice and changed the o ring. And that made a difference.

I have watched a bunch of videos of other folks complaining that the rubber seal on the coils don't sit flush. And this coil that I have definitely does not sit flush. So at this point I'm inclined to blame the coil.

Had I never dropped it I could be 100% certain it's coil related. But since I did drop it I can't rule out other issues.

Ok Dbro just gave it a shot. Gonna see what happens. Will post results later tonight.

Hmm...If you put in new coil and it doesn't sit straight/flush, I would say the impact buggered the threads in the base. And if it leaks with the juice level below the joint between the coil top and the chimney( as in the pic), it's gotta be the rubber seal in the coil or the coil bottom o-ring. Also check the floating pin in the tank base. It should move in and out without a coil installed.(I had one get stuck once and it leaked out through the airflow holes. Had me cussin' for a minute. Lol)

Thanks for the response gakudzu. The coil itself actually sits straight its the black rubber ring around the ground wires that seems to be causing the issue. there is a tiny gap there due to the wires sticking out a little.

I took Dbros advice about screwing in the tank coil to top cap first and it seems to be working pretty good. Been vaping pretty hard on it for about an hour.

Edit - whats the floating pin?

That little base is just press-fit. You should be able to straighten it. Sometimes I get one that's a little crooked, too.

Hope you got it whooped :cheers:

Hey guys thanks to all of you that helped out and gave suggestions. Just wanted to post some updated results in case other members or google searchers find this helpful.

Today I did my own build with some .4 claptons and I am happy to report there is absolute no leakage. Looks like my issue was coil related.
