How do you know how hot it's running. You say normal operating temp is 170 deg. You can't put you hand on 170 very long. I work in Hydraulics and I've got a lot of practice touching oil resovoirs and believe me you won't be holding your hand on 170 long because the metal contducts heat very efficiently.

When you read the whole thread it becomes obvious to me the problem seemed to start after the rebuild of the valve.(but then what do I know 
)The pump is working overtime to try and make it work. Did the power assist work after the valve rebuild? Have you had a chance to test it?

Just watching thread,so I went and ran my Vette(78) and checked powering steering pump temp after a drive around the block...(waited till engine got up to temp)
After a 1/2 mile drive,with engine still running in driveway,I got 154 degrees F on the forward pump casting...
Raytek Mini-temp MT-4...

When I first tried the PS after I had done my conversion to RHD the steering did a violent turn one way. Turned out the new hoses were blocked on one side where they were silver soldered. Check all your hoses for blockage before you change the valve and pump.
I have since converted to rack and pinion so I dont have any of the "standard" problems any more.

Thanks! (I guess you do know a lot...)

If you put the hoses on backwards the steering wheel ossolates back and forth really rapidly causing the frame around the steering box to flex badly.

Your pump should never get so hot that it "burns" the fluid off the outside of the reservoir or pump casting. You have blockage in the control valve, or you have a defective pump.
You might just try the following. Disconnect the pressure hose from the control valve. Now connect a 3/8 ID hose to that end. Take the other end of the 3/8 hose and connect it to the reservoir spout. You now have the pump set up to just recirculate fluid. Make sure the reservoir is full of power steering fluid to the FULL COLD mark. Now start your engine. If the pump is quiet and sounds normal. The problem (blockage) is in the control valve.

I'll check this - only one hose is new and I don't remember blowing through it to check.
Jim,
I'll try the recirc. trick tomorrow. I ordered a new valve. Thanks for all your help.
I'll report my findings tomorrow.
