Jeff,

can't tell for sure. If it is the whistling sound, it could be coming from the air intake somewhere. Other than that I can't help.

By the way, your van does shine very well. Nice detail work!

did you check your vaccume brake booster ? it kind of sounds like a reed blowing in the wind, medium pitched. do you have any vaccume lines toward the drivers side? one time i heard a simular noise and it ended up being some sort of leaf stuck in the heater intake trap but it would change pitch when you changed the fan speed. if it's mechanical, then i'm leaning towards the a/c area. that noise seems like it is eminating... not making noise right in front. i would take the dog house of and see if you hear it better. i couldn't hear if it changed with the rpm cause as soon as you opened the door i couldn't hear it anymore.

Your van now sounds like a train. Thought maybe a pulley bearing, but no, is something stuck in the throat of the tb.

I'll have to let it sit over night and then pull the dog house off because to make this problem even weirder is it'll only do it after it sits all night and only does it until it warms up for the first time of the day its cranked. also it has hydroboost so it doesn't have vac booster
