Hmm, blue smoke at idle would mean the valve stem seals were shot, not unusual on a turbo engine. More common on a modified turbo engine, since the exhaust valves get a lot hotter as boost goes up. In fact, if you could peek inside your valve cover after a hard run on high boost you'd see the exhaust valve stems glowing just a bit. Not as much as the turbo's themselves, though......
