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.
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.
