sounds like your throwout bearing or a pilot bearing. It's one of those things that can start at any time. They tend to just get noisier and noisier. I think I left mine in bad shape for about 6 months befor eI did anything about it. If you've had your clutch done recently, then it's either the pilot bearing (sometimes they don't replace that) or it's a bearing inside the tranny, and it's going to be a pain to take care of. But most likely the throw out bearing or pilot bearing...
