Narrative:

Climbing through about 6;000 ft we got a left engine bld ovht EICAS message which caused a left engine bleed off and a left pack off to display. I accomplished the engine bld ovht checklist and was unable to correct it. Attempts to contact dispatch via satcom were unsuccessful because the call was 'unavailable' via ACARS the dispatcher provided an arinc frequency and we were eventually able to talk to dispatch and maintenance control; although it was very difficult to communicate because of the background noise and feedback on the frequency. (Satcom did eventually work but we were already on the frequency and just about done with our conversations) maintenance control did not have any additional information to correct the issue. Although the dispatcher stated that he did not find anything in the flight manual that would prohibit us from continuing to [our destination]; with the left pack off; the left engine bleed valve closed; and the bleed overheat condition; the crew determined that the safest course of action was to return to [departure airport]. We coordinated with dispatch and [operations]. The flight attendants were notified and the test was done; the cabin was not prepped; and we accomplished the diversion planning guide in the QRH. At this point we had used all of the center tank fuel so were unable to dump and determined that we would be accomplishing an overweight landing. An electronic log book entry for the bleed condition and the overweight landing was accomplished.
