95 Disco I. The power steering pump has been making a rattling noise for a week. Yesterday it starting belching fluid from the pump outlet on the "pump to box" pipe. I tightened the hose and the leak held -- for about 30 minutes. I notice now that the leaking is not coming from the hose coupling -- but from what looks like a lock nut or something on the outside of the hole. The hose is a brass pipe with a O-ring that fits into the hole. The hose has a brass nut that tightens. The leak is not there. The hole on the bottom of the pump has a much larger (at least 23 mm) nut around it which I never noticed before (and can't get a wrench to without tearing it apart more than I want to).
Opinions? Any chance that tightening the larger nut might solve the problem. I also wondered if the O-ring could have gone bad but it looked okay and the leak is not coming down the pipe -- it is seeping out the side of the above described larger nut. This pipe is less than 6 mos. old but was not a Rover part (Atlantic British).
Or is the rattle noise the "death rattle" of the pump?
