I've done the EHM, and was wondering why is there so much smoke vapor comming from this vent? Looks pretty bad at night. Is this top-end pressurized from piston ring blow-by? I would only expect this from an engine with significant wear.

It is pretty normal...high compression ect.

Mine does it too. At night you can see vapor rising up through the headlights. It's more water vapor and oil mist than smoke, so not much to worry about.
