Your symptoms sound very much like a clogged crankcase breather system. Get that checked out, at a minimum it will cause an increase in oil consumption and damage your CAT converter, at the other extreme we've seen complete and engine failure.

| | I took the car to the dealer and they said it is a valve on the intake that lets in and out air and thats why it sounds like that and that its totally normal is this bs. And if so what can i do to make them fix if they say its normal.By the way thanks for replying and for your help. |

| Its hard for me to diagnose this over the web.
I would suggest a second opinion as the whistling sound you speak of isn't normal and you might want to find out what it is.
Try another dealer, check out an independent at http://bimrs.org/, or give us a call if you're close by. You can drive it in & we'll give it a listen to right on the spot.
Good Luck!

Sorry for the late reply, but I'd have that evaluated as well.
