Trickflow Upper intake manifold whisteling

[ajaffer]

Has anyone had this problem where it makes a squeaky whisteling noise only at idle which sounds like its coming from inside the manifold? It just started this week and i thought it was a bad vacum line but i replaced them and its still making the noise.

maybe is not the intake, do you have a BBK throttle body, because usually they make a whisteling noise.

The BBK is notorious for the whistle.

Get used to it like I did, or buy an accufab, or motorsport. Supposedly they don't whistle near as bad

check to make sure all the hoses are connected underneith the upper intake. one of mine was cracked and it made a horrible whistle.

I took off the upper intake manifold and found a cracked gasket which was causing the annoying noise, case closed. And the BBK was never whisteling before so getting used that noise was not an option.
