I'm not sure about the 5.9 CR, but the 6.7 does burn crank gasses - it gets sucked through a big filter on the valve cover and then goes into the air intake before the turbo.
But that isn't going to cause a huge problem - maybe get a little oily residue on the compressor wheel and inside the intercooler.

EGR does cause problems...you get SOOT caked up in your intake and the only way to get it out is to boil and scrape it out...
My jetta had an EGR and all it was good for was clogging up my intake manifold with soot and costing $1500 to have it boiled out so I could get my 10mpg back that I lost form a clogged intake manifold.
EGRs should have NEVER been put on diesels due to soot. soot does not just go away on cold parts (intake side)...it builds up on things. and will only go away if you run it hot. (you can clear your turbine on your turbo by holding your EGTs at 1200* for several miles on a grade should burn it off)

hummm, maby the newest 6.7's might bun the gasses, but a friends 07 6.7 does not, i put an intake on it a while back, but none of the 5.9's do and like you said, it really isnt going to hurt anything anyway, and can always be rerouted anywhere you like if it was believed to be a problem
