While driving, starting at about 25 mph. It sounds like a helecopter and gets louder with speed. There is no vibration. When sitting still you can race the engine but no noise. I have put the van on jack stands and put the engine in gear at about 2000 rpm still no noise?

Do you
have the same problem?
