the oil separators in these cars do not like short trips in cold climates that last under 20 minutes. if you continually drive the car without fully warming it up and ridding the separator of all condensation, it will freeze when the car cools down and block the tubing. if it remains wet it will also corrode the inner tubing and narrow the passage causing blockage as well.

I bet it was this

I bet the reason was frozen breather tube. When it freezes, the engine always injects the oil out. Before it happens, a lot of white smoke comes out and after few seconds, the failure happens. Usually there's a nasty "burned oil" smell.

I had it happening 2 times this winter. Especially with older engines, they start "breathing" more. When it happens, the moisture comes to the tube and when it is cold it starts to freeze.

After the second failure, I installed a specific electrical warmer around the tube which should keep it always open.
