ththanks to the previous replies on my noise....

how can i tell the difference between a worn clutch noise and worn idling gear noise?

998 mini special 1989 lhd

If the noise comes on when you depress the clutch then you should suspect the clutch release bearing. If the noise goes off when you depress the clutch then suspect idler gears or gearbox bearings. idler gear noise will be there all the time when you are driving, if the noise goes off in 4th gear it is probably a gearbox bearing. Hope this helps and if someone has already replied with similar, Sorry I am slow typist

The noise goes off when I press the clutch on my Mini, so is it something to worry about?

thanks tommy,

the noise stops when clutch pedal depressed, the sound gradually stops....is this gear box bearings or worse?

noise is there in 2,3,4 gears whilst driving

cheers

When the idler starts to go it's first a rumble, then changes to a rattle, then a whine... when you get to the whine stage, it's likely that both the transfer case and gearbox case will need replacing..

After a whine, comes a bang, and that the idler gear letting go and time for a complete strip of engine and box.

Mine only rattles in neutral, but the noise goes when I press the clutch.

There's no noise whilst driving.

thanks for this, I think!!

so it should not be driven until sorted....this means engine out and replace these bits....no other solution?

do I need any special knowledge to fix this....I live in France so mini specialists are a little scarce.

any idea what sort of cost am I looking at for the parts, best economic way!

Yours will be a clutch release bearing I reckon.
Shouldn't worry about it too much. Don't sit with the cluch depressed at lights or rest your foot on whilst driving.

Okay thanks.

I don't think there's anything up with Taffy's car. When the car's in neutral the transfer gears can chatter as they're free wheeling with no load keeping them pressed together. If the clutch is correctly adjusted the release bearing only spins when the clutch is pressed enough to bring it in to contact with the clutch pressure plate. Another test is to coast in gear with the engine turned off and the clutch held in, the only bit of clutch turning will be the friction plate.

if it was the diff it is less serious but it would be in all gears.

 

engine out time and full rebuild over winter.

My Mayfair had a rumble but I left it alone. Then it suddenly started sounding like it had straight-cut drops. I didn't check the shimming of the idler gear when I changed the gearbox. When I split the hosing apart the idler gear looked like this:

 

 

There were also bits of teeth everywhere. Incredibly the engine was ok. It's probably a good idea to check things.
