I recently replaced the two O ring seals on my Vickers power steering pump as the pump was leaking badly. The front seal was in good condition so I left it alone. Unfortunately the pump still leaks but to a much lesser degree. I tightened the pump bolts without a torque wrench so it is possible that they are not tightened evenly. Would this be the primary cause of the leak? I look forward to some advice.
