I quote from the May 2011 issue of Diesel World Magazine.
"Special care is needed to preserve the turbo on that first startup. The little bit of oil you applied on assembly isn't enough for operation, even for a short time at idle. The best procedure is to leave the oil line off to prevent the engine from starting, but crank it over until you get oil from the line. Then, hook up the oil line and crank the engine in 15-second increments three times giving the starter time to cool down in between. That ensures that the unit has received a good amount of oil. At the least, use an oil gun to pump a good amount of motor oil in through the oil inlet before you start."
