I would take the valve off and flush it good in the sink. It may have dirt
in it and be in and be leaking. Or you may have a slight compression
leak putting pressure in the system for this try a bottle of Bars stop leak.

GM... I'm pretty sure (nearly positive) the radiator is plugged, not allowing 'free-flow'. And, yes, there is a good chance of contamination in the 3-lb valve. The valve has been there for a few 'seasons', and easily could have accumulated 'stuff'. I've done the usual tests for compression leaks - found nothing.
Thanks for the suggestions.
