My power steering setup is as follows:
1.) 1969 GM power steering box
2.) Braided stainless hoses (new)
3.) GM Type II power steering pump
4.) ZOOPs remote resivoir
My problem is this- It continually pushes fluid out of the weep hole on top of the resivoir, and the fluid foams up like crazy.
Seems like an easy problem- it's not bled, right? Well, bear with me.
The first time I bled it, I spun the wheel 10 or so times, topped off the fluid level, and then had the engine running while I turned the wheel back and forth a lot. Pressure built, it took some fluid, and I got power assist, so I removed the cap and let the foam subside. Started it up a few hours later and it was still fine. I took the car out for a drive and it slowly lost power steering, and pushed a lot more fluid back out.
Thinking I bled it wrong and still had air, I called up ZOOPs and asked what they said to do. They said to put the wheels in the air, leave the engine off, and spin the wheel 50 times from lock to lock. This kind of sucked (try it sometime
) but I did it, and the assist returned and works fine.
BUT, the fluid is still foaming, and it's still pushing out of the weep hole. It's not overfilled as the resi is at 2/3 exactly. I triple checked the hose routing, including making sure the diverter is on the right port in the resivoir.
My question is this- how much air is IN a system like this. Once you get constant assist, isn't it pretty much done being bled?
