You basically poor it into cylinder through glow plug hole and let it sit a little and try to move the crankshaft back and forth a little to make sure the liquid makes it way deeper into the piston rings. If you are lucky you will unstuck it and will be able to turn the engine freely. But probably the best way to approach the situation is to get the glow plugs out and check the front belt timing marks. If the marks are ok then great. I would get a cheap borescope to look inside the cylinders and you will understand better what is going on there. You can rent it from autozone or advance I think even. But my guess is rust. "

What do you think about this statement?
What do I think about this statement? Your buddy might be a good mechanic but his statement shows he does not know much about the important particulars of this engine: "...the best way to approach the situation is to get the glow plugs out and check the front belt timing marks. If the marks are ok then great."
Except-- there are no front belt timing marks.

That is why I patiently took the time to recommend a simple first step you could perform to help identify what might be going on with the engine internals. Do you have a reason why you do not want to do that?

Here it is again: You could do an easy test to see if the engine might be intact inside. Put a 27mm socket on the crankshaft pulley bolt and with a long ratchet or breaker bar rotate it a few rotations, feeling for valve-piston interferences.

Do that and report back the results.
