You can use spyder cup seals, just thread them onto the pin/stem, probably need to use pliers to get the old one off. But it sounds more like the seat on the valve has a scratch on it, take it out and sand it with a fine stone, lapping compound, sandpaper on a block, however you do it just make sure to keep it good and flat, then polish it up nice, should take care of your leak. The leak might also be causing the pressure to not stay steady if the leak is bad enough.
Thanks, I will give that a try this weekend.
