I did a couple of flights on the same aircraft last year with CF-6 engines that had encountered some sort of bowed rotor start. I suppose they have sensors that send the info to maintenance. Anyways, both days during the turnaround at the outstation, maintenance came on board and did a motoring procedure for about a minute or so at the gate.
