Oil Filler Tube

[joltesvig]

My oil filler tube has baffles in it.
I take it those are to keep oil from splashing up and out of the breather cap.
I notice that a LOT of smoky oil fumes normally come out of the breather.
The fumes are normally HEAVY to the point where they come up through the floor boards and can be seen on a sunny day inside while I'm driving.
Is it normal for Model A's to give off a lot of fumes out of the oil filler / engine breather tube?
