I believe you are right! I have a torn intake boot and I get the whistle and I also have the same problem as the threadstarter. Cool air when stationary and hot air when moving. I just had my water pump replaced with a metal one about lesd than a year ago! Im gonna replace my intake boot within the next week. I included a pic down below. Sorry if you guys get offended by the dusty engine. I definitely want to clean it but im new to this!
