3.3l engine noise

I have a 2005 grand caravan 3.3l. when driving it seems to have a
slight rattle in the engine, once we hit around 43mph it turns to a
slight whistle or similar to a high pitched frequency sound. the faster
we drive the more profound it gets. It only does this while giving it
gas.
I brought it back to the dealer (still under warranty) they say it is
just normal drivetrain noise. I find this hard to believe. we love
the van but this sound is too annoying.

 

Keep taking it back to the dealer!

Why not get a second opinion?

My 2003 T&C, with the 3.3l, had an alternator that started to make
noise last year when it had about 40000 miles. I don't remember the
exact noise, but I used a 'mechanics ear' to locate it to the
alternator. I think the noise was probably coming from the pulley
damper that is attached to the alternator pulley. I went ahead and
replaced the alternator, which came with the pulley and damper, and the
noise went away.
