The "hose" is the crankcase breather.
Any compression or combustion gases that get past the piston rings into the crankcase are vented to the atmosphere thru that pipe or hose.
The grey smoke that you see coming out of there is called "blow by".
If there is a large amount of blow by, that means the piston rings are worn out or broken and the engine needs an overhaul.
I have also seen blow by caused by worn exhaust valve guides allowing exhaust gases to flow past the exhaust valve stems.
In any case, if you have an extreme amount of smoke or vapors coming from the crankcase breather tube, then the engine has problems.
White smoke from antifreeze entering the combustion chambers would also be seen coming from the exhaust, not just the crankcase breather.
