Narrative:

Immediately after takeoff we experienced a very strong acrid smell in the cockpit. Confirmed similar smell in cabin. Followed smoke from unknown source procedure. Declared an emergency and returned uneventfully to dfw. Landed overweight but very smooth touchdown. ATC a little slow in allowing us to descend due to traffic. Would rate their performance a 5 out of 10. Flight attendant during emergency and after was outstanding. First officer's performance and attention to detail outstanding. Callback conversation with reporter revealed the following information: reporter stated an engine seal failure had caused the fumes and smoke problem. He said the problem was noticed at approximately 1000 ft. Both captain and first officer donned their oxygen masks and continued climb to 8000 ft. After they completed their emergency checklist, they were given vectors back to dfw for a landing on runway 17C. He said dfw had a lot of traffic at the time but handling by the controllers was satisfactory.
