You could try introducing some leak sealer into the system - all you need is
access to the headertank (remove some water first) or any radiator that you
can ratially drain enough to get stuff in the top vent. That should seal it
fine.

Hi,

Just put up a new radiator, a hulking great vertical thing that was a
bugger, mainly through being so heavy. Now I've just noticed that
there is a teensy leak where one of the tails goes into the rad. I
guess I didn't tighten it enough (it's got PTFE tape on it). The only
way to fix it would be to drain the rad, get it back off the wall and
take an allen key to it. It's dripping at the rate of about one drip
every two minutes (probably even slower). What are the chances of it
healing itself? Maybe I should encourage a little sludge build up!

Cheers,

Martin
