Whistleing engine...

[Kenny]

Could be the elbow on the air box intake. It makes a noise when pulling in lots of air.

I took mine off - made a deeper sounding intake - cool....

It might be your Intake Manifold Gaskets -- especially if you've also noticed any odd or irratic surging RPMs at idle.

I just replaced my intake manifold gasket to remedy the same symptom. My whistle could be heard even at idle, but became louder as the RPMs increased. I hope your whistle is from something easier to fix. Good luck.

I hope your whistle is from something easier to fix.

Agreed.

However, there is a 'Cheater's Trick' to doing the install that makes the job go a whole lot more quickly...

Instead of actually removing the Intake, if you have an extra pair of hands around to help-out, it is *possible* to lift the Intake up off of the studs just enough to remove to old Gaskets and slide the new ones into place.
