Hi Art,
could be the copper gasket under the cap is squashed out into the plug thread relief area and the asbestos insert in the copper ring has adhered to the top face of the filler neck.
Check and see if there is a gap between the cap under-face and the gasket. Springiness will be the cap threads trying to cut a thread thru the distorted gasket and/or lifting/jacking the gasket from the neck face.
Cheers,
Eddie B.
