i have a 95 gst i was driving it home approx. 4 miles i wasnt runnin the shit out of it or racing. the turbo started to howl like a ghost, well it did that for about 2 miles then the turbo completley stopped working, and now smoke is pouring out of the exhaust and somewhere in the engine compartment, the motor isnt knocking and it isnt idling funny therefore i dont think the motor is blown. if the turbo goes out will smoke bellow out of the motor??? please give me some advise on this

thanx trae
