Why does my 04 6MT make a cricket-like sound when I'm taking off in 1st? It only happens when it slightly goes below idle. I've heard of this problem before and don't know if it's normal, or is there a solution.

I get a new engine through Nissan soon, under warranty, however just curious as to what this is.

Could it be bearings? Alternator?

 

Belts?

 

Clutch???

 

Not the clutch, it can be slightly heard with the clutch in , or out @ idle.

I was thinking the belts too, or the tensioner.
