I'm feeling abit paranoid. So I wanted to share my thoughts. From the first day i bought my evo, it always had a bit of whinning sound. After searching i've concluded that a little whine is normal and a bit of noise from the engine bay is normal. The car never gave me any problems. Over the course of a year I've slapped on an intake, tbe, engine damper, fuel pump, and a mail in flash. The whine has always lingered in the back of my mind, thinking maybe my tc is the cause of whine. What i dont understand is if the whining is caused by the tc, why is it that when im parked in neutral and i rev my engine the whining noise gets louder with the rpms. I've always kept up with all the maintenance and the car drives like a champ, but paranoia is a pain in the ***. Anyones input on this would be greatly appreciated.

 

throwout bearing..completely normal guaranteed- you will get used to it..
when you upgrade your clutch it gets even louder

 

never thought it could be the tob. Ill search into that. thanks for the heads up.

 

Probably a tensioner pulley or pulley of some sort. If the noise goes away with the clutch in its your TOB, if not it could likely be a pulley. Take your accessory belt off and start your engine.
