Check the O-ring slot for porosity and/or rough spots. Any deep scoring, etc in the slot can keep the O-ring from sealing. Some wheel bearing grease won't hurt, either, to fill any shallow irregularities.

Make sure the O-ring protrudes sufficiently from the slot when installed, too. If it doesn't crush enough, you won't get a good seal.
