Hello SupraManiaks!<br><br>I just rebuilt an engine for a '90 NA Supra. The old engine had a rod knocking... However drove fine. Now, after I dropped the new engine in (Which runs great), My power steering pump whines and I cannot steer easily.. The fluid level is full and I never disconnected any of the lines... What happened to my PS Pump??? It was fine before! I'm probably going to order a new PS Pump from Toyota, but it bugs me that mine just quit like that!!!<br><br>Any Ideas???<br><br>Thanks,<br>Tim

That could be a couple of things as well. First, it could be the pump just finally wore out, it happens. It may also be that when you moved the pump around while you were working on it, the motion dislodged some old gunk in the resevoir and that's what made the pump go TU. But before you go replacing it try these options. <br><br>First check and see if you pinched one of the steering hoses when you changed the engine, if you kinked any of the metal parts, or what have you.<br><br>Second try to see if you have some air down in one of the lines. (and that could have happened when you moved the pump around -still attached to the lines- and put it in a position that air enetered the system) Crank the wheel all the way to the left and hold it on that position, you know so the pump makes that noise that lets you know it's hit the stops, keep letting it make that noise for a minute or so. That will keep the hydraulic shuttle vavle in the open position and cause fluid to run through the system purging any air. Then crank the wheel all the way to the right and do the same thing again. If there is air in the lines somewhere or down in the vlalve, that will cure the problem.<br><br>Those are the simple, quick and dirty, alternatives.

To GTman. I do know it takes time to bleed the power steer system if it has air in it(I r+r,d press hose) There is a process to bleed system-you have to be persistant. don
