I don't think so, the only thing with a diesel is that you're dealing with much more volume of blow-by because of the high compression ratio. Be sure Not to restrict the flow in any way.
There's basically two ways to do it.
One, is to simply vent to the atmosphere and live with the vapors & smell. If you run the tube up over the booster (so the oil carried by the vapors drain back into the engine) you shouldn't have much oil to catch and, since you're living with the smell and all, you could just let it drip a bit. My truck, with very low miles, has never dripped a drop of oil...
Second, you bring the vapors back where they belong (minus any oil using the catch can) and into the turbo. This also makes you "smog legal"
as well as eliminates the orders & steams.
