i found a high pitch whine coming from my engine when i start it up and run it. it gets higher pitched the higher i rev. i cant quite tell where the sound is coming from but i'm not sure if its a belt or something worse. any help would be greatly appreciated thanks. i have a 95 f22b2 btw

 

Alternator diode bridge getting flaky? If so, it would change when you turn on every blower, headlight, defogger, etc...

Recent/new timing belt? Too tight?

 

i havent had the timing belt changed since i bought the car. The car didnt start doing this until my transmission was going out. if i start driving it it will make the noise along with the speed of the engine. high rpms high pitch. you get the point. sounds like a belt to me but i honestly have no idea

 

Can you get someone to rev the engine while you look under the hood and try to pinoint the noise?

 

i was trying to do it myself by reving it from under the hood but it was hard to focus on where the sound was actually coming from. ill try to do it when i get home later.
