Most likely your wallet. :mrgreen:

Have you actually listened under the hood to see where it is coming from? Have you checked your power steering fluid?

Power steering fluid is ok. but the noise is so difficult to locate as it seems its coming from all parts of the engine

Check tensioner pulley or idler pulley for bearing wear.

Check water pump, if the pump is original and its worn it too will squel happily away as the impellar is made of a kind of plastic and is designed to squel as it starts toucjing the timing cover.

You could use a length of pipe to locate noise source but be careful it dont get caught in the belt

How bad is the whine? Mine whined a little... During the winter I put 5w-30 in it :naughty: . This caused a slight whine, but nothing to go cry about.

The originals were plastic!?

Mine was metal... (MY 2000) - and leaking from the small hole in the middle of the axle....

The Squeling is either the missus, SATNAV, whatever animal or person you just ran over..... - No seriously - I'm guessing tensioner pulley or idler pulley for bearing wear as well - have changed the tensioner on mine - made it quiet again :shhh: Or maybe the alternator - the can also produce terrible noises - but bearing can be changes for a small cost at a local hardware store.

Try to take the drivebelt of - that way you can establish whether it's from inside or outside the engine - try to take the cover of the EAS as well - to rule out the compressor for the airsuspension.

The belt is loosened by taking a 15 mm socket and a wrench (clockwise when seen from the front of the car)

You get a Piece of Pipe, Screwdriver or the likes off or even the proper tool for the job which you can buy, and stick one end if your Earhole and the other end on say the body of the Alternator and you should be able to determine if the noise is coming from that component or not.
However please do not stick it on any revolving as this could be quite painful to both your Earhole and Wallet. : :cry:

Original Water pump impellar is plastic, when the bearings wear it starts to touch on the aluminium timing cover, when it touch its whines instead of eating awy the aluminium like the steal impellar would do.

Many manufacturers water pumps are constructed this way and aids as a warning

The steel impellars on Aftermarket pumps are because of costs

Hi All, did the pipe test to determine the source of the noise.found the noise coming from two sources. The Power Steering pump and the other item close to the power steering pump(that lies between the Power Steering pump and the Alternator). dont know the name.So what is the next step. is it possible that these two items are faulty?

It's British - anything is possible!

If you haven't heard of Murphy's law - buy a British car!

I wasn't aware that 5w30 was a bad choice?

Last time I experienced a mystery whine it ended up being my water pump.
A couple summers back, I start the engine and hear a funny whine. Hrmm. Pop the hood, start nosing around with the engine still running...then all of a sudden I'm covered in a mist of what appears to be really thin oil! IU was baffled, but it turns out my water pump insides had grenaded and was spraying water and picking up grime and crud from the engine bits on the way to my face so it looked dark in color. I stopped the engine and grabbed the fan and wiggled it, when I would pull it one way water would gush out from around the water pump shaft, when I would let go it would almost stop.

Also, for pinpointing mystery noises, I picked up a mechanics stethoscope, its basically similar to a medical one except the pickup is a long metal rod so you can touch it against various engine bits and really nail where a noise is coming from. I think I got it at Harbor Freight or some other cheapo tool store for peanuts, probably was only a few bucks at the most.
