Hi,

After 3 years the cap (black plug with X) started leaking again and a
whack with a hammer doesn't help anymore.
Does anyone know if this is screwed in, pressed it, glued in? Does it
have a seal? Has anyone taken it apart?
Is there a flange on the inside like a rivet or is it just pressed in
(tapered).
I can make another plug at work, but can't drive to work to make it if I
take it apart.

Any help would be great.

Thanks
