Is the inflow of air/water caused by the rapid chilling of the diffs?

A clogged or seized-shut breather will cause the seals to leak due to heat expanded and contraction of the air, the seals blow out, or suck air or water in. The breather cannot do it's equalization job.
Heat is caused by how hard and fast the diff is working taking in consideration of +/- outdoor temps. I've had Ice buildup on my diff, the pressure will build before the ice on the housing would melt so the breather is frozen, not doing the job.
Gravity dictates regardless of diff temps, there simply isn't much air in diffs and axle tubes, to have hot diff air "blow" out, and rapid cooling, sucking more water in, than gravity, maybe a little bit, but I doubt it.
I could be wrong.
I say we send this to the Myth Busters and have Kari do an experiment.. :coffeedrink:

That 2nd gen silver pickup that went through: Where is his air intake located? If it is in the stock location, I am surprised that he made it through. I thought the water over his hood would surely stop his engine with the stock intake right behind the grill on the driver side.

The air intake on a Gen2 Tacoma is inside the wheel fender, behind some louvers, and with the intake pointing backwards so water does not splash in.

Stock location. I'm surprised too. I though he would drink the muck water for sure.

This is my rear axle breather bling.. LOL
I know, I know, overkill, but heck why not. I have a pile of pneumatic parts in a box laying around and decided to slap them together. Overkill for sure, but after inspecting it a few weeks ago there is some moisture in the separator... Very little but made me wonder. I changed the diff oil, didn't see any water mixed in, so maaaaybe the separator actually works?

O ok, i figured it would be the same as my 4runner but i guess not! That design sounds preferable to mine which sucks in air from behind the grill next to the driver side headlight. I will look into the truck setupfor sure!
