Hi, I was just wondering what could be wrong with my car as there is a grinding sort of noise when I do slightly high revs and a lot of black smoke comes out of the exhaust at the same time.. I have a feeling it could be something to do with the clutch but I'm not sure which part of the clutch it could be. If anyone has experienced the same problem can you please let me know as I don't want to be spending a lot of money on a complete clutch kit. Thanks in advance.
