Next oil change I'll have the tech poke around and see if they can bend it. Oh if you have an intake and HFC you really need a tune.
I also have that rattle. Glad it's not something loose. It's pretty consistent and I only notice it when starting the car up cold... once it warms up, no more rattle.
