Narrative:

After landing in ZZZ; we parked the jet at gate and accomplished the engine shutdown and associated checklist. Since I was receiving a line check; I accomplished the walkaround inspection. There was a small amount of exhaust smoke coming from the rear of the #1 engine; and the fire department had been called. I told them to get a ground fire extinguisher; and went to visually get a look. Upon inspection; I did find flames on the rear turbine blades of the #1 engine from the 10-12 O'clock position; however; it looked to me as if some residue (oil or fuel) was burning; not a fire that was being continually fed. The flames quickly died out on their own approximately 15 seconds later. The fire department call-out was canceled before they could respond. I called maintenance control and they contacted contract maintenance. Upon his inspection; no damage was found; and per maintenance control's request; the flight crew performed an idle engine run at the gate. All engine indications were normal; and there were no egt exceedances. The return flight to ZZZ1 was uneventful; with all normal engine indications.

THERE WAS A SMALL AMOUNT OF EXHAUST SMOKE COMING FROM THE REAR OF THE #1 ENG; AND THE FIRE DEPT HAD BEEN CALLED. I TOLD THEM TO GET A GND FIRE EXTINGUISHER; AND WENT TO VISUALLY GET A LOOK.
