Power steering control valve leaking again

Hello, I am have trouble with the pscv. It leaked from when I bought the 80 corvette a year ago. To pass the uk mot system and get it road legal I need it not to leak. So I bought a rebuild kit and rebuilt. All good for a week or so and now it's leaking again. It's seems the steering fluid is coming through the ball stud and washing the grease away which I'm sure this is not meant to happen. I really want to sort this out and not purchase a recon unit if I can help it. Any advise please.

did the kit come with instructions such as these and you saw no corrosion or marks inside the bores?

Ok, I may try and rebuild again and double check with this info. Thanks

Be careful greasing the valve as too much may damage the seals. I was told by a valve rebuilder to grease it sparingly and with the car running.

Here is a video we did on the rebuild, it may possibly help you.

Been there, done that. Either you had a poor quality kit, have a bad core, or you messed up. It is easier the second time. The above video helped me.

He may have cut the seal putting the two halves together, I know I've done it before. (probalby why I don't build the valves here, my guys do them all now).

If you go to the 8.15 mark in the video you'll see what I'm talking about.
