There is a pop coming for the steering buy only when I turn to the passager side. I can feel the pop in the steering wheel it is so bad. I have traced it back to the control valave because with the car off it is fine when I turn to the drivers side but when I turn to the passager I can hear gurgling from the control valve and I little fluid comes out where the valve screws onto the tie rod (the car is a 68 302). I just rebuild the valve around christmas time and have only put about 1,000 mile on it since. Any ideas what I may have messed up?
