I was thinking about that but looking at it today, it seems that it goes away with alittle higher rpm. When i press the clutch the rpms go up slightly. You can still here it but not as loud. Its driving me nuts.

Sound from engine I Bought this skyline about a year ago and recently it has started making this noise that i can not pin point. Its driving me nuts and nobody else seems to know ethier. Was hoping someone here could help. Its like a really high pitch whine and it will go away when i depress the clutch pedal. Any help is appreciated! 20170416_171355.mp4
