First, I don't want to hijack the thread, but my question is highly related to the subject.
-------------
I did have the "low oil pressure" in question. I just did the oil sump O-Rings replacement. The weird thing is that the first thing my wife notice afterward was some sort of fan noise. Then I realized that it was valve noise which sounds like fan noise as you accelerate.
So, why do I get the valve noise after the O-rings replacement? The low oil pressure light went away though.
This is what I think. I know my Oil Trap is due to replacement due to oil leaking in the area. Could it be that now all the o-rings are replaced, there's no way for the trapped engine pressure to escaped (due to oil trap clogged) that somehow cause the valve to knock?
In addition, it seems the car doesn't accelerate (losing power) as good as before my oil sump o-rings replacement.
Or could it be that when I drop the sub-frame (left hanging), I could had accidentally unplugged some wiring and/or vacuum hoses to cause this high pitch valve noise and lack of power?
Please advise, thx!

Since you dropped the sub-frame you might have worked the collar out of the boot in the floor board. It will make it sound like lifter noise inside the cabin while driving. Look where the column goes through the floor board see if a metal collar on the shaft is loose. If it is use spray silicone on the boot and press the collar down into the boot. Sometimes you have to stretch the boot some with a screw driver while pressing the collar in.
The other clue is that when I turn left or right, there's like a rubbing noise of some kind. I check and add the steering fluid already, but the noise is still there. I have a feeling when I dropped the sub-frame, the steering boot/rubber or something like that came off/stretched from the connection that goes to the steering wheel column. ((Is this the area you are referring me to investigate?))

This is a very low mileage 2000 S80 non-turbo, only 67K miles. I suspect something happened (came loose) when I drop the sub-frame to do the o-rings. I highly doubted that the engine just turned completely bad just because I did the oil sump o-rings. I understand that would happened if I did something wrong when replacing the timing belt. (which is my next project)

"collar out of the boot in the floor board" Tech, what exactly are you talking about, please be specific in the direction where to look. Like, driver side (left) around gas pedal or right side looking from top down near something.... etc.
