My little brothers car,
Any of you guys know what could be the cause of this?
The car runs quite nice, but for some reason this happened and now this is the only thing it can do..

You can hear a knocking noise, don't mind the slipping belt.

That noise doesn't sound good but might be unrelated or have a less serious cause.

You are sure the squealing noise is from a belt? Is something seized causing drag on the engine and causing the stall?

Oil level and pressure normal, no other symptoms? Did the noise and the stalling issues begin at the same time? Did they begin suddenly or did it get worse gradually?
