hey ive got a 93 civic with a b20z/b16 tranny and in the morning or after my car sits all day when im at work i get this whining noise out of it, its priety loud and hight pitched but goes away after you drive it for a minute. cant figure it out almost sounds like a bearing but the only one i could think of that would do it would be the altenator (dont have p.s) but its not louse. could this sound be transmision bearings ? i know my release bearing is bad and i need one of those. but eaven when the car is just ideling in neutral it sounds like a dry bearing noise cant figure it out

 

Does the noise persist even with the clutch depressed? If the noise is still there with the clutch pressed sounds like a drive belt bearing, or something to that effect. (IE pilot bearing, P/S pump)

 

pilot bearing is a good guese, but yes it does. could a transmision bearing do that ?

 

pilot bearing is the problem

 

Take off the alternator belt and start it in the morning when it usually makes noise.. My guess is timing belt tensioner and if it is fix it asap..
