Lately when I start my 67 up in the morning, I can turn the steering wheel to the left with no problem, but when I try to turn it to the right, I have no power assist. If I force the wheel to the right, eventually I begin to get power intermitantly. Within a few minutes of that, I have normal power steering throughout the day, but the next morning it starts all over again. Fluid level is fine, but it is an old pump so I replaced it. The problem did not go away with the new pump. Could the problem be in the steering gear?
