I'm starting to think I really made a mistake buying this truck. I'd love to get everything running well, but stuff keeps coming up. I heard a whining noise when steering yesterday. Went and looked at my ps pump, no fluid. So I filled it up, and ran it, only to find a nice leak. After searching all over for the source, I finally found it. Right where the master cylinder bolts to the hydroboost, uh thing. You know the thing that the hoses from the ps pump run to. I took the master cylinder off, and there's no gasket, none of the parts stores carry a gasket for that. Local GM dealer looked it up and they showed me a 'spacer' that I needed. Anybody have any experience with this system? 92 Sub 3/4ton, 454. Thanks a million in advance.
