2011 coupe with v6/6sp manual. At apx 1200 miles I noticed a "woodpecker" noise from idle up to about 1500 rpms. This is at operating temp, not at startup. Local Ford mech could not hear what I heard. Now at apx.1600 miles the woodpecker has turned into a small ball peen hammer. The noise can now be heard up to 2000 rpm. The frequency of the unfriendly noise leads me to belive it is bottom end and not valve train. Once again this is on a normal operating temp motor with good oil pressure. Am I the first to have one of these new engines go sour????
