Re: Goose #5

From 1100 miles away this is pure speculation, but.... Here 'ya go. Worth what you're paying for it.

Pulling air into an air intake, especially one that might have a little frost on the filter, creates a restriction/venturi that can absorb some heat as it goes across the restriction. If the humidity is right, you'll get frost in the restriction. I suspect that hour you ran the engine, the air filter was accumulating frost and perhaps accumulated a thick coating of it. Next day in Durango, that frost had thawed and dropped into the filter base. Now it's on the low pressure side of the filter and going straight into the engine.

I've got a high efficiency furnace that, in the right damp weather, will freeze the screen on the air intake full of frost crystals to the point the furnace will shut off. It's 1/2" hardware cloth, but I've cleared a thick coating of frost off that thing multiple times. It takes just the right combination of humidity, ambient temperature and furnace draft.
