Hey ya'll, as the topic states, my '92 runner 4x4 with 293.5k miles on it, is making a very loud noise like if someone was murdering the flute (switches from low-high pitch flute-like noise) located in the area of the middle-back to the bottom bottom of the engine., mostly around the back bottom-ish, with quite a bit of noise in the middle-back top area as well.

If anyone has an answer before I take it in tomorrow, it'd be greatly appreciated.

Thanks ya'll!
