I have a '88 coupe that has a recurring issue of leaking out all of the power steering fluid. This seems to only happen after it sits for a long period of time (several weeks) in the garage. As soon as I move it, it starts dripping. I can't find the source of the leak, no oil on belt or anywhere else that I can see. The rack is dry with no visible leaks either. Once I drive it, it stops leaking until the next time it sits for a while again and then starts all over after the first drive. Any ideas?

 

I have the same problem. No one on the forum has the answer so far. One friend of mine who owns a Mustang had a simular problem and it was a worm PS pump bearing. Once he took the belt off the fluid poured out.Its to cold to work on it now but that is my next try.If it works for you let us know.
