Re: 67 PS

First of all, check to be sure that you have the power steering lines correctly connected in the system. In this case, check to be sure that the extend and retract hoses are properly connected and not reversed. It's very easy to do this. Follow the diagram shown in the N-40 section of the AIM.
It's also possible that you have a defective valve. I understand that some reproduction valves, and even current GM valves, may suffer from a defect in manufacture which can cause symtoms like you are experiencing.In Appreciation of John Hinckley -
Re: 67 PS
Ron - one of two things.....the power steering control valve balance is WAY off, causing the violent turn (less likely as these are balanced when rebuilt, or second, the hoses between the control valve and the hydraulic cylinder are reversed. I have heard reversing the hoses causes this exact symptom. It is easy to flip them on installation if you are not careful...CraigComment

Re: 67 PS
I reversed these hoses and, for me, everything was OK with the steering wheel more or less 'on center' - not the valve, the wheels were centered. As soon as I started to turn the wheel one direction, it whipped all the way in that direction with a whole bunch of force. I had put a kit in it, had the hoses reversed, figured I screwed it up, took it to a local, reputable place for rebuild, then figured out I had the hoses wrong. I figured it out from staring at a picture in the Chassis Service Manual, I believe. Even then, the valve itself was non-centered enough to move all the way to one end, then squeal the P/S belt.

Re: 67 PS
Thanks to all responses. I'll check the hoses tomorrow. I thought I triple checked them on installation, but it never hurts to do it one more time. If the hoses are correct, I'll give the vender a call.
I'll let everyone know the final results.
Thanks again,

Re: blown control valve
if you cross the lines you will blow the seals in the control valve. hense the problem you have. only one cure and thats to install new seals or put another unit on. alot of people do not take the time to make sure they have everything plummed right and are unaware of what will happen.Comment

Re: blown control valve
Ron --
Bet you a dollar it's the control valve. I did this once many years ago and a friend did it just last month, about took his arm off! He reached into the car thru the steering wheel to start the car. Needless to say, the wheel began to spin, bruised his wrist and broke the turn signal lever. Both solutions were to adjust the control valve with the nut under the dust cover.

Re: blown control valve
Ditto on the control valve. I would think this would be awful touchy for the re-build vendor to successfully "final adjust" on the bench. I put one on six months ago and was handed the control valve in one hand and the dust cap in the other. Just for this reason. I was also warned not to stick my arm through the spokes in the steering wheel until I got the valve adjusted.
As for the fluid, you need to add just enough on initial start to get fluid to the valve to adjust it. Then slowly fill the system while turning the wheel from full left lock to right. Shut the engine off and let it set a minute. Give the steering wheel a quick quarter turn yank (engine off) to "burp" the system. You should now be able to top it off.
As far as your fluid boil overComment
