2002 Disco, about 3 weeks ago noticed a small weeping PS problem. It was the adjustment nut. Sealed that up, then it started coming out of the connection to the high pressure line. I replaced with the best oring I could match locally, and it didn't help. Worse, even...

I figured that the power steering pump pressure relief valve was going, since nothing else would suddenly force the fluid out of random places. Replace the power steering pump, got some official o-rings, and guess what? Still leaking.

I have both o-rings on both pipes. The metal plate seems flat. Any other ideas?

I've seen a few other threads like this, and everyone seems to say replace the hose, but it isn't the hose bits that are leaking, it is the connection. Unless the metal has gotten 'used up' or something supernatural, I can't imagine replacing it.

I replaced steering box, low pressure hose, all o-rings, and new pump gasket (pump and bearings looked new)
Used high quality, high temp sealer (Yamabond).
Truck sat over a month before starting.
Next day, ps pump leak.
Had blown out gasket on top side of pump, wtf.
I have yet to do anything else with it, too many other things to fix on it right now.
