For some reason, whenever i push in the clutch... and after a small delay... i hear this weird noise. I don't know how to explain it properly, but it sounds as if something is spinning around rubbing against something. It only happens when the clutch is pushed in.

Anyone would know what that is?

TIA

Throw-out bearing possibly.
I had similar symptoms (my car did actually) several years ago, but I don't recall if there was a delay between depressing the pedal and commencement of the noise. -But I do recall parking it immediately, jacking and placing jackstands, and giving the TO bearing a few small carefully aimed shots of a dry lube PTFE product (it required the supplied extension tube plus another home-made extension)(def don't want to get any on the clutch's friction surfaces). With that (if not by coincidence), the noise went away and never returned. Still driving with the same TO bearing today.

Pilot/spigot bearing. It's the end of the torque tube flailing around. It'll get a lot worse and requires the gearbox, clutch and TT off.

+1 on the pilot bearing. The delay before the noise gives it away. When the clutch pedal is out the pilot bearing is doing no work, when you push the pedal in it releases the input shaft, or in this case drive shaft, and the shaft begins to slow down from the engine speed, as it slows down the pilot bearing begins to move, the more the shaft slows the faster the pilot bearing has to move, and if it is dry or wearing out, that is when it will begin to make noise. A throw out bearing typically makes noise whenever there is pressure on the pedal. Often a failing throw out can be detected by slight vibration felt through the pedal.

Starting to make the slightest noise. Any helpful pictures of how to make a guide to apply the slightest amount of grease. Angles,positions, easiest way.
Greatly appreciated.

This sounds like my problem, too.

Quiet apart from the long day to drop the transmission, are replacement bearings hard to find?
