Noise go's when I press the clutch, also iv been feeling a little bit of vibration though the clutch pedal, from some looking up on the matter seems to be a common problem yeah it knocked twice, very strange if you ask me ,iv seen other cars doing the same on the net , I'm going to do a valve adjustment tomorrow but I only have feeler gages in mm ,and only 015 mm and 020 mm that is the closest to 006 008.
