help identify this noise
 

alright well i bought a car off a friend as a project car and it has turned into a longer story then i wanted. i did a lot work just to get it started and rolling but now i have an engine light and the engine makes a loud squealing noise. i think i can probably figure the light out but the noise i cannot figure out.

here is video of the noise.
