What Power steering
So while replacing all 4 of my power steering hoses i went ahead rebuild the pump, 10$ you can't go wrong. I was "bleeding" the system of all the air and i thought i got all the air out, thankfully i decided to take it around the neighborhood first and quickly discovered it was extremely stiff. I followed the pictures from Ecklers and placed the hoses in the right spots. What could still cause this problem? After that drive i left the car running and was turning the wheel to the extreme right and left and still no bubbles or foam in the pump afterward......?

Line blockage somewhere? Check to see if you are getting fluid at all the line junctions. Next see if the pump is making any pressure. Can you see the fluid level changing any when you turn the steering wheel while the car is running?

What exactly did you do to rebuild the pump? Took off the reservoir and replaced the big o-ring? Took out the discharge fitting and replaced the o-ring on it? Replaced the driveshaft seal?

I haven't had a chance to check if its making pressure but a blocked line seems like the problem, the control valve was covered in dirt so some might have clogged the line. I replaced all the o rings and the shaft seal

You may have the flow control valve(pops out when the discharge fitting is removed) and spring in reverse order. Should be spring in first, then valve, then discharge fitting. Ask how I know about this....

I seriously doubt that your problem
is a plugged line. A restriction in the line will cause the pump to make a lot of noise before failing. I think it could be that you assembled the control valve incorrectly into the pump.
Make sure that the control valve goes back into the pump with the hex nut first.

I agree with Jim............................. a lot of those instruction sheets don't have clear pix about re-installing the control valve ! I installed it wrong -- with the valve asm control first and then the spring............. didn't work. Reversed them as in the good pic above and it worked like a charm !
It's nice having an asset like Jim on this forum to help keep us straightened out !!!

thanks guys your right those guides they sell are crap. I was following one by the letter well i ended up with the end plate not in yet and no where did it say put it back in. Amazingly it wasn't the control valve, it was a missed place o ring on the #24 on the picture the fitting asm. i had put it on a grove short of where i should have put it, and when i moved the o ring up one grove it revealed a tiny hole that allowed fluid through.
thanks everyone,

Have you seen this site?

I had the PS pump off this summer for a cam change, painted it and it leaked from the mounting bolts. Hope to use this tech sheet to fix the leaks this summer.

i remember a headlight diagram that was wrong at the switch. that thing floated around for a while and you could never narrow down the leak . just didnt make sense, until i think durangoboy redrew the diagram the CORRECT WAY then it all made sense. THE ONLY ONES I GO BUY ARE IN THE aim and sometimes those are (still after 30 years) "waiting for approvals"!! LOL!
