I have a 68 c code coupe equiped with power steering. The pump has bad seals and is completely dry, so of course its not working. I have been driving it anyway just using arm strength. Only problem is there is a large dead spot, or play, in the steering. I have heard that this is because the p/s valve isnt operating. Will replacing the pump solve the problem, or will I have to repair more of the p/s system? Any advice would be greatly appreciated, thanks.
