you have to click on the video and it takes you to photobucket, but its the circular saw almost sounding noise. its actually around 3500 to 3800 rpm, i dont think it is mount related at all, it sounds internal

Yup sounds like something rattling to me. Jack the car up and crawl underneath and check the heat shields, I bet there loose.

It does t really sound like a rattle and it's the exact same rpm every time it's consistent. It's almost as if it has to do with vct or imrc activating but it only last for a a few hundred rpm then it's gone and returns as roms drop back down through that little window where it occurs. I'm like 100% it's not heat shields or mounts or anything.

I'm not that familiar with IMRC action but for sure VCT activates all over the place rpm wise, it does not come on at any one point, ergo, not that.

Until you get down and pin point where the noise is coming from then we're all just guessing here.

Mine has the same rattle but only when the gas is gently pressed down. Once I press down a little harder the noise fades... Mechanic couldn't explain it... :-p
