Narrative:
After normal takeoff performance, engine ran rough and vibrated at approximately 400 ft. Immediate turn to downwind and simultaneous call to tower declaring emergency. Power was reduced to maintain altitude and further reduced when landing was assured. #3 cylinder was identified on the downwind leg as faulty (cht out of range). #3 cylinder had been reworked at annual the prior week (logbook notes were later mailed to me because FBO ZZZ computer was down when annual was completed. Flts from ZZZ direct WWW direct XXX direct YYY all normal engine performance). Touchdown and rollout were normal. After shutdown fresh oil was pooling under the engine. When cowling removed, #3 cylinder was visibly cracked.

Narrative: AFTER NORMAL TKOF PERFORMANCE, ENG RAN ROUGH AND VIBRATED AT APPROX 400 FT. IMMEDIATE TURN TO DOWNWIND AND SIMULTANEOUS CALL TO TWR DECLARING EMER. PWR WAS REDUCED TO MAINTAIN ALT AND FURTHER REDUCED WHEN LNDG WAS ASSURED. #3 CYLINDER WAS IDENTIFIED ON THE DOWNWIND LEG AS FAULTY (CHT OUT OF RANGE). #3 CYLINDER HAD BEEN REWORKED AT ANNUAL THE PRIOR WK (LOGBOOK NOTES WERE LATER MAILED TO ME BECAUSE FBO ZZZ COMPUTER WAS DOWN WHEN ANNUAL WAS COMPLETED.
