Flange Cover/Crank Shaft Question

After replacing the flange cover on a LEV120 shouldn't I be able to hand turn the crank shaft? This is my first time doing this, so I have no idea what's expected.
 
Before reassembly I applied a light coat of engine oil to the cylinder wall and other internal parts including the oil seal on the flange cover. Without the flange cover on I can hand turn the crankshaft. I am aligning the camshaft and oil pump/slinger in their slots as I place the flange cover back on and with a little jiggling the flange cover seats fully. But once in place, without even fully tightening the flange cover bolts, I cannot hand turn the crankshaft. Is that normal, and if not, what might I be missing? 
 
Thanks
