I have a 1990 rover Mini check mate 998 that has started screeching really loudly wether i'm in gear or in neutral, the harder i rev the louder and more persistent it gets. I've checked the belt from the alternator and it seems to be pretty tight, it's also in pretty good condition as far as wear is concerned. There's no leaks from the radiator etc everything is pretty spot on. Any suggestions on anything else it could be? It stops screeching when the clutch is pressed in but starts again as soon as you let the clutch out.
Thanks in advance
