Hi, On my 06 ody with just 100k miles I'm starting to hear astrange engine sound, it sounds like it's coming from the front engine bank under the plastic cover, It sounds a little metallic and goes away very quickly, under hear when i step on gas from idle and then it goes away fast. Kinda sounds like when one of the brake dust shields rubs the rotor but this happens when car is not moving also, it seems it's RPM dependent
