front-end noise

my 02 venture ls with 42k is making a very annoying noise upon startup and up to 10 minutes afterwards. the noise is best described as a buzz/rattle. is seems to be coming from under the front end, under the radiator. it gets louder as the engine is reved and goes away upon warmup. the dealer has attempted to fix it 4 times now. they have tightened all heat shields. does anyone have any ideas?

I would be curious to find out the answer to that one too!!! mine is doing the same thing, kinda like a rattle..

I had a problem like that on my '99. It turns out the prop rod for the hood was not tied down properly. The plastic clip was partially broken, and caused the rod to vibrate against the frame. A few dollars later, no more buzz. But, my problem was more constant than yours appears to be.
