Funny noise from gb/clutch
After driving a while (i.e. when the car is at operating temp) and you depress the clutch to change gears it makes a screetching noise that seems
linked to the engine speed - i.e. the tempo of the noise fall as the enige speed drops back to idle. As soon as you take your foot of the clutch
(either in gear or neutral) the noise goes away)
Even when you just slightly depress the clutch while driving (not enough to disengage it) it will make the noise.
It does not always do this, and I haven't been able to establish a real pattern other than the engine + gb must be warm.
any ideas?
BTW 1600 xflow & 4spd escort GB.

Worn/damage spigot bearing -- check one is actually fitted as they are often removed if the crank is reground and not replaced.

My vote is also for the clutch release bearing...
You'll have to separate the engine & gearbox to get at the clutch, so you can check/change both anyway.
Both parts are cheap as chips...

Clutch release bearing shouldn't screach though... more of a grumble.
I'm going with BT!

As I said, both can be changed fairly cheaply once the clutch is stripped...
... mind you, getting the bearing out is a real PITA!

Nope peice of cake. Two methods.
1). Get an old gearbox input shaft, then pack the spigot bearing centre completetly with grease. Push/hammer old input shaft into grease filled hole
and bearing hydrualics out. Easy.
2). Visit friendly neighbour-hood hardware store and purchase RAWLBOLT of appropriate size (8.0 - 10.0 mm I think. Should take either 6.0 or 8.0 mm
bolt). Then you will need a suitable long bolt to fit and a very stout suitably large diameter washer. Fit bolt and washer loosely to rawlbolt, insert
into spigot bearing and tighten till bolt starts to grip. apply equal leverage to either side of washer and out pops old spigot bearing. cost of
puller - a couple of pounds. Job Done.
Hope this helps. Enjoy.

Wouldn't have thought that slightly depressing clutch would have caused spigot bearing to screetch . If engine has to come out to replace clutch
it would be a good idea to replace it , as David says cheap as chips
