Hahaha. This might be related to topic: I too started to have weird whistle sound coming from the engine. It usually starts about 1 min after start and it pitches very high and lasts for a while. I've replaced all the hoses.. How can i pinpoint the origin of that?

I'm with Gary in NJ it sounds like a vacuum leak. Check the lines while the car it running. You might want to replace these hoses soon little cracks can mess-up the vacuum system.

Check your oil the engine has a little raddled sound to it. Have you tuned the valves yet?
