I'm fixing a power steering leak on a 96 Grand Prix. It was leaking pretty profusely before I parked the car, fast enough it would drain the reservoir in a trip or two. I had a hunch it was the power steering pressure hose, so I have that off the car and am going to replace it. But just to confirm this was the bad hose (and not the return) I tried pressure testing it with air by capping one end and using my air compressor @ the other. It holds a fair amount of pressure and isn't leaking.
I tried this on the return hose, and it too, is holding pressure... I don't know where else this fluid leak could be, there's nothing else on that side of the car where all the fluid dripped down onto except the two hoses.
Is it possible there is a leak in one of the hoses, but my crude way of pressure testing just isn't finding it? What is a surefire way of telling whether one or the other is bad?
