I'm chasing a whistle and can't seem to find the source. It only manifests itself in 2nd, 3rd or 4th gear under light load. As soon as the turbo starts to spool into boost, the only whistle is the turbo. I've traced all the vacuum hoses, intake gaskets, I still can't find it there. I do have a header leak that is in the process of being fixed. When the headers were put on the new motor, regular felpro sandwich type gaskets were used and when the header bolts became loose, the leak burned though the gasket. It is possible that the metal remnants of the gasket are responsible for the whistle? It does ssem to coincide with the "spit and tick" from the header leak. I'm at a loss for the whistle.......
Thanks.
