Directional Power Steering Issue

[Dizzymole]

I have an astra h electric pump supplying a 92 Camaro steering box. The issue i have is that turning right, the pump changes note and I have assisted steering, but turning left, the pump tone doesn't change note or give ANY assistance. Been messaging people and googling but all i get are conflicting answers....or none. Logic tells me that the pump either works to supply the demand or not. But with limited knowledge of these boxes, I would guess there is a directional valve or similar that could be contaminated and blocked?? The box is smooth to rotate and very little play so doesn't seem badly worn and the hoses are new.

Guesswork on my part but it sounds like the pump is OK, it either works or it doesn't. I think I'd be rethinking the question, ignoring the pump, and look at it that you have assistance in one direction only, and see what you find.

Cheers for the link Chris. Certainly follows my logic of thinking that the issue most likely lies within the box area.

I won't go into great detail but you had new hoses made? was the old unions used and were any of fitted with valving of any sort ?

No, all new unions and no valving
