I just got my 84 Z running again after about a year and a half of it sitting and when i start it up it has this high pitch whine. I think it might be the turbo or maybe the intake but i have no clue. I dont know wether to buy a new turbo or not.
Help?

 

Pretty hard to help on such a vague description.

Maybe you could post a video, sound clip, or describe WHERE the sound is coming from?

 

im going to post a video up in a little while but the sound id coming mainly from the intake right infront of the engine.

Theres the link for the video of my engine. Sorry for the sound quality its not that great. also my engines pretty dirty. lol

 

Sounds like a vacuum leak to me.

 

Thats what my one friend said. he used to have a Z but he never had that problem. Just wanted to get a second opinion. Im going to take it to the shop near my house and have them check everything out on it to see whats wrong.
