As you can tell this noise could be many things. I making a few assumptions here. The a/c and fan motor are off, the vacumn pump and lines are fine, you have checked the noise Dean spoke and still not found the culprit, so with all that in mind, I would start to check items that contain bearings. If the sound was only when you started the engine, I would suspect the air-pump, the non-turbos have an air pump. The noise occurs when the car is running so thats not it. The alternator could be suspect, the A/C compressor could be suspect,(yes, even though its off), I don't know if the water pump would make that type of noise. I would check the belts and pulleys and also note any unusual smell emanating from the car, not from your friend BillyJoe. Seriously this is a tough one, I am just trying to think of all the things I would check. Good luck
regards,
Bryan C
