My power steering pump has been whining ever since I swapped reservoirs, increased pressure, and opened up he orifice. Im not sure if its an inlet line size issue causing cavitation, or the pump ran dry a few too many times with all the component swapping or what.
It still builds pressure and acts 100% normal, it just whines especially when I hit the brakes. I am wondering if the hydroboost is causing a back pressure issue.
I am going to try an external relief and a flow control valve to bump the pressure down and reduce flow. If that helps, then I will look into a bigger inlet hose and maybe porting the pump inlet.
It acts like air in the system, but it just never clears up. I put 12 hours of run time on it, and it hasnt cleared up.lol
