Ned, sounds like a good rumour!!
At the moment one machine in Namibia is out in the wops for a week flying around, and the other one is sitting in the hangar with nothing to do. What the guys you were talking to probably meant to say is that, a while back, there were some problems with the engines that P&W addressed through service bulletins (Fuel cooled oil cooler, Power Turbine). The only issue now that I am aware of, is sand injestion (funny that, flying round in the desert!!). At least one of the Namibia machines is trialling a Bleed Air Particle Sep, which will be a welcome addition when its certification is completed
