I know the oil smell (OH BOY, do I know it!!!!!) and it was very different this time. Think 1970's British car wiring loom short-circuit smell and you'd be about right. Acrid PVC smell, no 'blue haze' as you get when the RB211 oils the bleed system and it hurt the eyes and throat, which the oil doesn't immediately do.
I suffered a massive oil-out some years ago where the haze was so thick that it remained IMC in the flightdeck for 25 mins after chocks.
So.....how hot is bleed air when it exits the engine? I'd assumed that the eng info was correct and that the bleed air was overheating something since the punkalouvre (sp?) ducts above the front galley were pushing out hot air instead of the normal cooling blast.
PS Ground tested. Satis
