Blew off steering hose
Ok, so I know that my idle valve was on the way out, so... 
I disconnect the vacuum lines and cap them off. As well, I looped the hoses coming from the idle valve on the PS pump. This morning I notice lots of fluid in the garage, check under the hood, and see that one of the hoses coming from the idle valve is pushed off, allowing fluid to spew from the valve itself. Im thinking that this should not occur, as there should be no pressure thru the valve itself, then again, maybe the valve is so shot that its allowing fluid from the high pressure side of the pump through.
Any thoughts guys?? By the way, when I remove the pump to replace the valve, how does the reservoir remove? Is it just a press fit with an o-ring? Cheers & happy new year to all.

I don't know why the hose would be blown off. Your conclusion that it may be related to high pressure sounds logical.
You shouldn't have to remove the power steering pump to replace the air control valve. The valve screws into the bottom of the reservoir. You can replace it from underneath the car.

I don't know how others block off or loop those vacuum hoses without blowing them off. High pressure fluid leaks got to have a way out somewhere. Replace the valve and fix the problem for good!

Aquired parts today (from TOYOTA dealership), and will fix this gremlin on the weekend for good. But, I have to say that I really considered removing the valve and plugging the hole, looks like a M10 or so thread to me.

part number for the valve is 17630-16040 and it was $140 (Canadian) at the toyota dealership. I have to update my sig, but my car is a 90 LS400 with 200k miles (US imported car). I bought the car knowing that it had a PS leak, and that the fix was fairly easy. Should have parts installed later today or early Saturday morning.
