Ok, so recently my g35 has been making an odd chirping like noise when accelerating. I had changed the belts recently and thought it was just that, so I re checked tension etc.. All is good. So one morning on a cold start the noise started will at idle, so I pressed the clutch slightly and the noise is gone. Therefore I've narrowed it down to the clutch. Now it barely ever makes the noise at idle, but almost always occurs when accelerating in the 1-3k rpm range, and while accelerating hard at various rpms up to 4k rpms. It's a light chirping noise that sounds very similar to what a belt could make. The clutch is not sticking or slipping I have 57000 miles on my 04 6mt. Any ideas? Throwout bearing maybe??
