Good choice on going with Rosewood Diesel, they are a great company.

Prior to pulling your injectors, you did remove the oil rail drain plugs, right? This will drain most of your oil down out of each bank of the motor. After this you need to take a suction device and suck out whatever got down into your cylinders.(Also I prefer to start on the drivers side since there is more room. I remove the rear most injector so that most of the rest of the residual will be contained to that one cylinder.)

Upon installation make sure you leave your glowplugs out so that you can bump the engine over for 2, 20 second sessions to purge any more oil/fuel out through the glowplug holes. During this either unplug the IDM, or remove the IPR wire from the IPR to ensure the truck doesn't try and start on you. Make sure to allow sufficient time for your starter to cool.

Make sure you put the valve covers back on with a couple bolts before you purge the cylinders by turning the engine over. If you don't, you'll have oil sprayed all over everything! LOL!

No I did not where are the drain plugs and quite a bit of oil did make its way down will turning the motor over by hand get it all out the motor is out of the truck and on a stand cause I'm swapping frames and if I don't get it all out will it be bad for the motor I don't know how much it takes to hydro lock the motor or if there are any other conserns

I pull the injectors and let it all run into the cylinders, then I use a Mity Vac to suck out as much as I can, then purge it by cranking the engine over. With all the GPs and injectors out, and the engine on a stand, you may be able to turn it fast enough by hand to clear it. I've never tried that before, so I don't know for sure.
