Hi all, Very much enjoying the Z experience but have a question...
I have a 6MT. It makes a whine/whistle noise that increases in pitch in line with engine revs.
Only audible when stationery or travelling slowly as it is quite quiet. Sounds very similar to turbo whistle. It doesn't sound to me like a vacuum leak, more a whizzy something rubbing slightly on something noise. I have checked the belts etc. and all looks good.
Don't think it's the clutch or release bearing as there is no difference to the sound whilst operating it. I have done a search on the forum for this but found no results- I'm hoping they all do it and it is part of the character!
