1976 300D Engine "Prime"

I recently installed a used 300D engine in my 1976 chassis(115/114 body). The engine, chassis and body have been under various stages of repairs & detailing (my first attempt at a complete ground-up restoration). I removed the injector pump assy for detailing of the engine block. I believe that I have installed it properly and performed a staic timing (as per the MB engine tech. book).

Would there be any damage to the engine if I filled the tank (empty for chassis detailing) and with all 5 injectors removed, cranked the engine over (say 10 seconds cranking then waited for a minute and repeated) to circulate oil back into the galleries/bearings prior to attempting to start the engine.

Would I need to worry about the new glow plugs installed if I am just trying to turn over the engine for oil circulation. I am thinking of disconnecting the wiring to the glow plugs, good/bad idea?

After I have filled the tank and "Manually Primed", up to the injector pump, could I leave off the supply pipes from the injector pump assembly to the injectors and place a simple splash guard and catch basin over the ports during the recirculation stage of engine cranking?

I don't see any need to disconnect the glow plugs, expect it will run the battery down quicker. If you do want to disconnect them, just unplug the connector at the relay, it's easier on the knuckles.
