  I am hopeful that the engine will be free and that tools will not be needed to roll the engine over as you state. I have been able to break engines that were only lightly seized by gently rocking the crank back and forth using a socket wrench and wanted to be prepared if that turned out to be the case. If it doesn't free up easily then I agree pulling the head should be the next step. Thanks for the advice. James

You do not need a socket, or a wrench.

You said you were going to remove glow-plugs or injectors. With either removed you can turn the crankshaft by hand using the belt to the alternator. If it does not turn by hand, rust has probably set in between rings and cylinder walls. If this has happened, forcing things with a socket could break rings and/or score cylinder walls. If it will not turn by hand with injectors removed, I suggest stripping the head off. I was lucky once a long time ago using penetrating oil to free rings from cylinder walls, but I was very lucky to do it without damage.
