Last weekend I had 'clutch failure' with no warning, which was strange as the clutch operation felt good. Anyway, it turned out to be release bearing failure. Having taken the green gearbox end cap off, I found that the release bearing was completely broken up and burnt out, and the top of the bearing had friction welded itself to the release finger. Once I'd free'd it off I then found that pushrod would not come out, so figured the other end was damaged too.
So if the gearbox was coming out, I thought I'd better put a new clutch in it too. I replaced the clutch and release mechanism today, and changed the gear oil, a little worrying as less than a litre came out... and found one of the drive shaft cup plastic sealing caps was missing resulting in gear oil in the inner CV joint...hmm. The pushrod was indeed mushroomed and burnt, so had to be cut off.
I can only assume that at sometime in the past it has been driven with no free play in the clutch cable or by a driver that liked to rest their foot on the clutch pedal.
