Start the engine, grab a hose and lightly start spraying water on and around all belts/pullies and see if noise changes/stops.

Finally managed to do this the other day - noise stops for a second then continues.

Quick q - does the cas on a series 2 require the cas seal?

kind of, in the seal are 3 brass standoffs, they space the cas out the correct distance to stop you loading up the thing and breaking it

When the noise stopped for a second, where were you squirting the water ?

With engine off see if you can twist a A/C, PS or Alt belt more than 90degress with one hand. If you can, tighten it up. It May also be too tight and back off a touch if necessary.

Can you isolate it to a single belt perhaps ? Using a glass of water just slowly dribble it onto 1 belt and listen for change. If no change, move to next belt.

So, took it to the mechanic - needed brakes done - and they said the noise may be power steering needing a flush, either that or its the pump. Tightened belts a little but noise still there. Now to research how to DIY power steer flush...

Have you tried yet what I mentioned earlier about narrowing down which belt made the noise ? Get a plastic drink bottle and drill a small hole in the lid. Just do one belt/ pulley at a time and wait 20 seconds before trying next belt. You know the sound went away when you hosed the belts. How can this then be caused by PS fluid ? ones internal, the other is external.

Did you twist the belts and see how far they twisted ?

    • Thanks for the update I truly appreciate it. I was trying to figure out the sensors. 
    • My son recently purchased a 93 Skyline GTS25 (NA), I am hoping to get some insight as to what potential this car has.  I have auto mechanical experience, and I am capable of working on this vehicle, but I know nothing about it.  Where's the best site to purchase parts (maintenance, repair, upgrades)? What kind of upgrades are available?  Thanks again and I look forward to any information that you all have to offer!   Darrick
    • This is a pump I have used in the past; no oil ever leaks or gets past the regulator plug.I was trying to understand what caused Nissan to not only mention it in their manuals but to also state it's a replacement part yet the part cannot be found on my pump or on any new pumps and there doesn't seem to have ever been a replacement part#.  First time I've noticed something strange like this from NIssan.     
    • yeah I have brown peeking out from in between some metal sheets close to the hood hinges. Strut towers look fine, even around the edges. some images https://imgur.com/a/brGt3Tu the one that looks the worst is the panel(s) going away right near the firewall on the passenger side, from underneath. Driver side does not look that bad.
