I will be interested in the feedback on this one... I have the same problem with my Champs pan. Its a welded on nut and the sealing surface was not machined after welding. Heat from welding caused distortion in the sealing surface? Who knows... I have tried three types of gaskets (copper, rubber, nylon) and none of them fix the problem.

Agreed that at the price of these pans I was also left disappointed in the quality and attention to detail in their construction.
