Ok, nice to see things have branched off nicely, with the usual "I'd use airmanship and not follow the RFM" contributions. I like to think we did.
First thing: the oil loss was minor and only not a contributory factor - it was a consequence of superheated seals breaking down. The streaks were all vertical indicating post landing leakage. So no need to consider the 30 minute argument in this particular case.
Here's a scenario: you are presented with the following EICAS accompanied with that lovely burning paint/hot metal smell, and the cabin is full of white haze.
I'm glad it wasn't Cougar, CHC or BHL on a revenue flight.
