so just looking at it really fast, you have the seal on the bottom of the coil, so thats seals anything from the AFC from the coil, there's the seal on the top of the coil that seals the chimney
you have the 2 main seals for the glass
then you have one seal at the base of the glass
for it to be leaking at the AFC or into the AFC one of the coil seals has to be messed up or not seating right...... or its flooding somehow
i still think it needs to be completely broken down and washed/clean out, then dried really well to make sure all the seal points are not dirty, or have juice in them. i think once thats done it will be ok
For me, it was the base of the glass and the lower tank seals that were leaking and causing it to come out of the AFC. Once I replaced all three, I haven't had any problems with either tank leaking. I posted a pic of the leak around 20-30 pages back when I was looking for a fix.
