Your post either doesn't really get what's going on with the engine thing, or is misrepresenting it. If you're an airline and you want a 787 from Boeing, they'll offer you a choice of engines: you can get either the Rolls-Royce Trent 1000, or the General Electric GEnx. The current issue is corrosion and fatigue in the blades of RR Trent 1000 engines, which has nothing to do with the bleed-air versus bleedless thing. And isn't the first time Rolls-Royce engines have had problems in recent years. The Qantas incident in 2010 involved an uncontained engine failure of a RR Trent 900 on an Airbus A380, and similarly triggered a massive surprise maintenance burden for A380s fitted with Rolls-Royce engines. That's what 787 operators who chose Rolls-Royce are facing now, though the majority of 787s delivered have had GE engines.
