Narrative:
At gate with APU running for 30 mins, packs on for 20 mins. At 10 mins before push, cabin and cockpit started filling with heavy smoke through eyeball vents. All pack, APU, electrical indications were normal with no EICAS messages. Captain made PA announcement to deplane through jetway door right(2L). Called ramp to coordinate emergency equipment. Reviewed qrc. Packs and APU bleed were closed. Shortly after APU shutdown, maintenance suspected seal or bearing failure in APU. Maintenance confirmed later a seal failed allowing oil to enter the pneumatic duct causing smoke.
