Trust Modern Machining and building practices? Just a few years ago, Subaru/Fuji skipped a crank drill cleaning post machining and had hundreds of failed EJ255 motors in the states on their turbo wagons and cars.
This. Unless you have some fancy factory fill (Subaru and some other manufacturers do), I would dump it at 1K for cheap insurance. Just to be clear, insurance is (on average) a waste of money. But when you need it, you really need it. I just did this last night on my 1100 mile 2014 Ford Focus SE.
