Took the car to work today, and from first start up there was a terrible screeching noise.
Initially I thought it might have been the drive belt as I had washed it the night before with zip wax and there was a chance some would have gone on
to the engine.
However, it appears to be coming from the bell housing, my initial though is spigot bearing, but it has only done 600miles and the one fitted is
supposed to be heavy duty, anyone familiar with the noise that can confirm?...

Does it go/change if you dip the clutch? If so the release bearing would be prime suspect!
The slightest weight on the clutch pedal and it stops.
I'm pretty confident I can get the bell housing back far enough to apply some grease to it, can the bearing be re-greased or is it engine out
and fit a new one?

Spigot bearing is the one in the end of the crank.
Touch the clutch, you now push the release bearing into the clutch and the bearing takes load, so it could be making the noise because the release
bearing is just touching the cover plate, if it has a cable clutch loosen the cable a touch to provide a touch more slack. If hydraulic then shortern
the push rod a touch in the master cylinder.

The release bearing is always lightly touching the fingers in most installations. It does sound like a duff release bearing to me, and they are not
usually very easy to dismantle and re-grease.
It does sound like a bearing, not clutch release, but one at the front end, an idler perhaps. Can you run the engine for a few seconds with the belt
off at the front? That would eliminate waterpump, alternator, idlers and anything else that end.
Pity it stops if you press the clutch pedal!

I does sound like the release bearing, engine and box out time, it is'nt as hard as it looks, the secret is to use a good engine crane. While
they are out, you must check the gearbox mounting rubber.
Thanks folks, got the car on axle stands with the engine running this evening. The noise happens when the release bearing is just touching the
pressure plate fingers and rotating at a slower speed; I have increased the clearance between them by 1-2mm I have applied a small amount of copper
grease to the front of the bearing and in the side of it using a bit of plastic and the noise seems to have stopped, test drive to work tomorrow will
tell all...
