It could be a lot of things. I get plenty of gear noise from my drivetrain that can only be heard at certain times. Sherical bearings and solid bushings help to amplify it. What kind of suspension do you have? Where is the sound coming from? You gotta be more descriptive if your going to get any help.

it sounds like the sound is coming from the right front and it sounds like someone is in a tunnel and they whistel real loud it only happens in first gear. above 3000 rpm

Maybe it's a cracked vacuum line.

all the vaccum lines seem ok..
so i doubt its that could it be the alternator perhaps because i noticed some corosion on the positive battery terminal..
