When was the last time you thoroughly cleaned the mvp's 510 connection?
Qtip rubbing alcohol really get in there & scrub it, all threading too, dry with paper towel/napkin.
Is the bvc head tight in the base?
Are you over tightening the tank to base, just tight enough to prevent leaking, don't crank the tank down flush to the base.
When new base/tank gasket isn't broken in, over tightening tank can cause wicking problems.
Is this a colored, overly flavored, overly sweet or NET e liquid?
I prime a BVC by dripping drops on top of screen, allow time for each to soak in, keep adding drops until the wicking material visible in the body wicking holes turns translucent & starts to seep out.
This ensures the cotton is fully saturated.
I don't count drops, probably 8-10.
