Noises problem
1997 BMW M3 6 cyl Two Wheel Drive Automatic 130000 miles

not sure what happened...just bought the car and realized it was bone dry on oil after it started smoking, but then when i filled it with oil, it started making a screeching noise when i start it up?

Hi there,
remove the drive belt(s) and feel the bearings on all the pulleys for tightness and notchy rotation, the A/C idler is often the best place to start.
