Garth;97272 wroteJust remove fan alternator belt and start the engine as you sad recoed alternator I'd be surprised if that's the source of the noise
After removing the belts for alternator and water pump/fan the screaming has gone away completely so I guess that has eliminated the PS and brought it down to one of those two aforementioned accessories, if it had anything to do with anything under the timing belt cover then it would still be there after taking the belts off the aforementioned accessories according to my powers of logic. It isn't the belts themselves as I've swapped them out for new and the sound didn't change (originals were cracked and on their last legs), I guess it could be slippage on the pulleys but the tension was correct and the pulleys were deglazed and aligned properly...

Everyone has been validly concentrating on anything to do with belt / bush alignment and Garth with the cam belt tensioner, but here is some more thoughts:
Since you have K-Jet mechanical fuel injection this opens up other possibilites.
1. tighten the 3 bolts that attach the throttle body to the manifold.
2. the airflow sensor plate / fuel distributor relationship to the injectors - as we know what a screech a crap injector can make. For people with k-jet a cheap stethescope is very revealing as fuel flows around the system, and the injectors themselves are a good listen, and in my experience extremely rare that all 4 injectors sing the same tune.
3. Hows the engine running - nice and smooth?
4. Is there an oil leak from the front crank seal?
Then its over to the wheel bearing and dragging brake depatment.
After a run do both brake discs have about the same temp emitting from them? (dont physically touch them).
Is there a brake pad hot resin smell from one disc?
Jack up the front - do both wheels rotate freely? Grabbing the wheel top and bottom and rock - is there any or excess side play in wheel bearings?
The list goes on.....
Manual gearbox/clutch or auto?
You mention (and please don't tell me my power steering pump is knackered....) usually they grumble and click more than screech.
Thanks for the detailed breakdown Anthony, I don't believe it can be related to fuel injection, brakes or wheel bearings etc as the sound has completely gone once the belts were removed (to alt and water pump) and the car emits the sound whilst stationary. I'm going to hook up a short run of v-belt (I've got one of those adjustable jobbies with segments) first from the alternator on its own and then the WP on its own and will report back tomorrow, cheers Porkchop
PS it's the manual version with electric OD
