I changed my head gaskets about a month and a half ago. The car runs awesome. Unfotunately about two weeks ago a whisling noise started coming from the engine whenever Iam at idle or not under boost. It is so loud you can hear it with the hood closed, 100 feet away. Iam assuming it is a vacuum leak somewhere. but I sprayed carb cleaner everywhere on the motor and I/C tubes and it makes no difference. I also diconnected the vacuum hoses one by one with no change. The car drives fine, idles well and is getting full boost. What could it be? Help please!!! Thanks!!!
