high pitch engine whine..

[1NonlyAccord]

My car has just started to make a decently high pitch engine whine while in upper RPMs 2000-shifting..(stops during shifting and when let off the gas/under certain throttle possession)
Thought it was my turbo at 1st,but its sounds like when you have a cheap system hooked up and having that electrical feed back.(i dont have a system just radio,so i turned the power off and it still does it)

sounds like the whine i got when i installed a torque damper,If yall are know with that sounds like..but its been off for months months..

i have changed my clutch,and oil recently.
Starter last year and battery twice this year.
I believe the alt. is stock
has 135,xxx miles on it 99 accord 4cyl.

is it something serious or just another 6thgen noise?

Alternators make a whining sound when the bearing goes bad. Park your car and rev to 2000 to try and mimic the sound

and doing this will tell me what? the bearing is bad?

this maybe totally unrelated, but on my J engine, it used to make whine noise with AC on.

then i recently got timing belt changed, along with water pump, and also, hydraulic tensioner was bad.

after this, no whine at all under all situation.

well i read on google that something in the tranny could whine also,and me just getting my clutch replaced 2 weeks ago got me worried.

my volts are staying at 13.5 and goes no lower than 12.
