easy noise from the engine compartment but ONLY when i accelerate

[daniel72]

Even from 2005 (date of aquisition) i have an easy noise from the front side (engine compartment) but ONLY when i accelerate, no matter in what gear. Pls help me with an advice to detect the source of that noise.
PS: Sry for my english

What do you mean by easy?
A noise cannot be easy. (simple) (not difficult)

Do you mean a hissing noise like air escaping?

Thanks for your attention! About the noise - ->No, it is not like air, is more like a bearing or a roll!
