the suspect part for a power steering whine is the power steering pump, flush (very important) the system and replace the PS pump..

the power steering reservoir is under the altnator and idler pully on the bottom near the fire wall...this is by far the stupidest place every to put such a thing!!!!

I almost got this. Does the fluid level go down ever few days with no leaking hoses,no leaking cooler if you have one and nothing coming out of the steering rack boots. It has to go somewhere. if it just comes out the cap the pump is not pulling it and sending it to the rack so you should not have much in the way of power steering. Did you put a new belt on wrong if posible and turn the pump backwards. Only other possibility is a flow blockage. Pull the return line,disable the ignition and crank engine. You should eventually pump fluid completely through the system and out the return line like it was headed back to the resevoir.

Testimonial: "Thanks, I will definately try that. I think it is probably flow blockage"
did you overfill the fluid resovior? the cap is vented and provides no seal, so it the tank is overfilled it will bubble out the cap, if the tank is not overfilled you have a defective steering rack that is pulling in air through a defective seal and causing the fluid to foam and bubble out the cap vent.

Sounds like a difficult-to-replace hose has ruptured. Sorry, I don't have a diagram. The hoses (only 2- pressure line and return line) run from the pump's reservoir down to the steering unit behind the engine. It's a cramped place and difficult to get your wrench there to loosen and remove the hose. Sometimes you need to lower rear of engine cradle 2 or 3 inches to get to it.
I'm not trying to dissuade you from doing it-it can be done by a DIY-er, but wear protective ear equipment if you are curse-prone like me(lol).
Put a half-pint or so of fluid in reservoir, start car, get underneath (Be safety conscious!), and wiggle the two lines. You will likely spot the break-careful it doesn't get all over you. With that big a leak, anything other than a line break would be easy to spot on the pump or on the rack and pinion unit in back of engine mounted on a cross member. Good luck.
