The radiator cap on my 1930 A gets loose from engine vibrations/driving.
There are no unnormal vibrations, the cap is just very easy to open by hand too, you barely have to touch it and it opens.

Any ideas on how to fix this problem?
Radiator cap is a new one, same one that is sold through Snyder's.
Maybe I need to try and find an original instead?

a nice thick gasket should snug it up or try bending the "ears" up a bit.

I gave the ears a few taps with the hammer, seems to have tighten things up a bit.

Will do a test drive when it stops raining.

i will go with what ronn said. You can make a gasket out of an old inner tube or other material with a pair of scissors. You can also glue it on with silicone adhesive if you never or rarely have to add coolant.
