I've never had any problem with "oil" coming out my vent tube, but I've read the stories about it happening.  In those cases, I'd always assumed it was actually a very oil-rich vapor that was being blown out, rather than solid liquid oil.  I've also heard of oil foaming from crank impact, as was mentioned above, and figured it must be something like that causing the dense vapor to be expelled.  But this is all conjecture on my part.

Oil rich vapor
 "blow by" in my language and caused by compression getting past the rings, or holes in pistons.
