Leaking Radiator??

[crispy]

My radiator is leaking, now the thing is, its not cracked and the drain plug is in nice and tight, yet it still leaks

I have traced where it is coming from and i found this. The part circled in red is where the leak seems to be coming from, so my question is, is there something missing? or do i need to change the actual radiator drain plug??

PICS:

when you take off the radiator plug there is a little rubber seal thats on there..

you need to change that

i realise that, but the thing is the plug isnt leaking, its that little hole

hms.. work doesn't allow me to view pics, but there could be a crack at the bottom? when did you realise? did tyou do anythign before hand?
how sure are you that it's not the seal?
most of the time, it isn't the seal, i've resued my plenty of times, no probbers.

ive had this problem twice (2 different radiators) and both times ive fixed it by changing the seal

what does the seal look like? Cos that may be my problem, although i am still curious what that little hole is for?

its a little circle rubber thing that goes around the plug
