Narrative:

Shortly after takeoff, the captain called for gear up, and upon completion, the smoke master warning panel went on, and the bell chimed. The so silenced the bell and declared that there was smoke in the left portion of the main cargo deck. Shortly after that, the captain and I argued that we smelled smoke. I switched over to departure control as the captain called for smoke on the flight deck, and we donned air masks and goggles and established communications. We then declared an emergency and began a right turn for a right downwind for runway 28R at sfo. While the captain flew the approach to a level off height, I gave the controller our souls on board and fuel, the so worked on the completion of the emergency checklist, and the smoke began to clear. We continued the traffic pattern and landed on runway 28R without further incident. We taxied to parking and were followed by local fire auths. No further events occurred. Callback conversation with reporter revealed the following information: the reporter stated the cause of the smoke was an internal and external engine oil leak, allowing oil to enter the engine bleed ducts direct to the air conditioning packs. The reporter stated the engine was a general electric CFM56-502C and was replaced. The reporter said the national transportation safety board requested and removed the cockpit voice recorder and flight data recorder.
