When I increase the heat, I have 1 radiator that spits a bit above packing nut , can I reseal it?

    Yes, easily. You could first try just tightening the packing nut a little. Sometimes that's all that's needed. If not, back the packing nut off all the way, clean the old packing out, put in new and reinstall.

    While you're at it, wander down to the basement and check your cutin and cutout pressures. For a "normal" one pipe or two pipe system in a home, the cutout should not be more than 1.7 psi and the cutin around 0.7.

    No need for it -- it's for sealing threads, not for packing. But even the big box stores have usable packing thread... The packing seals the shaft of the valve to the valve body; the threads of the packing nut aren't part of the seal at all.
