How about removing the glowplugs and then attempt to rotate the crank. That will tell you instantly if it is truly a hydrostatic lock situation. Also it should then turn quite easily, no need to apply a lot of turning force and compound any damage.

Why not do a blow down test? One at a time, put each cylinder at TDC, feed in some compressed air and see what happens. Is there a reason this should not be done on a diesel?
