Is it possible to select a face in the UV editor and find it in the 3D View? I have a mesh which i have Smart UV projected , and i have many loose UV faces . I would like to know if i am able to select a face in the UV/Image editor , And make it select the face on the 3D mesh. Is this possible? 

I cannot select every face on my 3D mesh to find the correct face in the UV , That is very time consuming and confusing. Thank you.
In the header of the UV editor window there's a button named "keep UV and edit mode mesh selection in sync", an icon with an arrow pointing to a cube mesh.

That resolve your problem.
Consider that also in the UV window you can choose if to work with vertices, edges or faces!
Notealso: if this button is selected, you can't edit the UV islands.
