Power Steering Control Valve Rebuild Problems
I just drove it out of the garage for the first time since and it seems as if something is wrong.
When doing the adjustment in the last step, I got it to where my steering wheel was sitting right in the middle and not moving from side to side. Steering wheel was centered in position and looking good.
Now, when driving down the road, the steering wheel it not centered and about an 1/8 of a turn to the right. It also appears as if I only have power steering when turning left altho now that I think about it, my drive around the block was clockwise. when driving straight, it felt as if I had less resistance moving wheel left than I did right.
I felt as if I primed the pump right by removing belt and turning pump backwards. Fluid level seems to be good.
Any advice?
Thanks, Cody
Update: The only thing I can think of that I could have done wrong was prime the pump. I thought I knew which way was backwards. If facing the car from the front, the fan spins clockwise, so I figured all the others would be spinning clockwise as well. After removing belt, I primed it by turning it counter clockwise.

Lack of fluid isn't the issue I don't believe.
Thanks though

I think after that I would double check the balance of the valve.

You successfully balanced the control valve since you state that the car goes straight down the road without pulling left or right.
Your car does NOT need an alignment since changing the PSCV does NOT affect the alignment.
Bad choice of words in my first post, I should have said an alignment shop can 'Adjust the tie rod tubes to bring the steering wheel back on center'.
You said that the steering wheel is off center to the right so here is one way to correct that problem.
If your steering wheel needs to be rotated counterclockwise to bring it back to center, the left tie rod assembly will need to be lengthened and the right one shortened.
Turn both tubes an equal number of turns in the same direction.

The reason I suggested a re-balance was "when driving straight, it felt as if I had less resistance moving wheel left than I did right." That's usually a valve this either has an issue inside or one that is not balanced correctly.

I did it this way and found that it was the same as before. This way made sure I didn't have any misaligned or directed parts. I also cranked the wheels both ways and held it there to bleed out any air.
Still no difference. What the heck is going on?
Any more advice?
Thanks, Cody
Just my 2 cents

Give yourself an 'A' for effort. Since this was your first attempt at rebuilding the PSCV you did very well!
Someone like Willcox who rebuilds many of these could spot a worn part or an 'O' ring or seal that was not made properly.
One can read or watch youtube but having an expert guide you through a few rebuilds helps.
It was a good learning experience but it might just be time to order a rebuilt unit and get your Corvette back on the road.

I guess live and learn. Going to pick up rebuilt PSCV tomorrow and get this puppy on the road again. Its been too long and the weather is looking good.
Thanks everyone, Cody
