I had pretty much the same problem with my 51. It turned out to be the wrong radiator cap. The right one has about a 1" drop (Distance from the top surface of the filler neck to the bottom surface where the rubber gasket is supposed to seal. Check that. The cap you have may be only about 3/4" which does not seal at all.
