So with this socket I've tried to rock the engine to no availability. Got comfy under the car and dropped first and last rod nuts. Last (closest to the firewall) dropped right away and first took some persistence to come off. Obviously the first one is the problem and why the engine was seized.

Engine is turning freely now. I took a closer look at the bearing in the first cylinder as it looks like it has spun half way through. I was unable to take this bearing off or disconnect two half
What are my next steps? How do you take off the bearing and is it possible just to replace the bearing (probably on all 4) and put everything back together? I suspect the answer is no as the crankshaft probably needs to be machined.

I'm wondering too.
Maybe someone mistakenly filled the tank with petrol instead of diesel?
And all the glow plugs I've ever bought have had rounded tips so those flat-ended tips look odd to me too.
I've drained the diesel (full tank) that was in it and already burn it fine in my other cruiser. As for glow plugs, they are rounded, just look like flat from the picture

On the second thought I took a closer look at the last bearing and it has lots of scars.
I believe there should be a hole in each half of the bearing and on one of them it is filled with metal. Probably the stuff that came off.
This gets me thinking that this could only happen there were problems in the oil system, read no oil pressure.
This points me to the oil pump.
Thoughts?

Hey great youre getting foreward !
For now i can t help you because my actual knowlege doesnt alow me but im gonna follow this interesting thread !!
I hope you can make the engine run nice again with not to many costs !

At least we're now seeing clear evidence of the "engine seizure" that the PO advised.
In these circumstances I think it would be a waste of money to simply replace the big-end bearings and hope it'll run fine again.
What do the big end journals on the crank look like? Are there any scratches deep enough to catch your fingernail or does it look like it'll just polish up? (From the look of the caps it probably needs grinding and undersize bearings now.)
Whatever the case, the whole shebang really needs to be stripped fully now and every part inspected/measured (and replaced if necessary) before the engine should be used again in my opinion.
I'd lift the head and see what it looks like from above before deciding what to do with it. (ie. Before deciding whether to keep it, whether to sell it as rebuildable, whether to sell it for spare parts, or whatever.)
Furthermore, it would be best to uncover a reason for the lack of lubrication too ... So a look at the cam bearings might be in order because they've been known to disintegrate to cause poor oil pressure.
(I haven't heard of 3B engine seizures caused by oil pump failures but cam bearing failures are documented not infrequently.)
BTW - That socket looks rather small for a crank pulley bolt? Mine requires a larger standard socket with no need for long-reach.

My crank pulley bolt is 24 in good uncomplicated european size.

Thanks guys. My natural curiosity has subsided now since we know why it has seized. I am gong to switch to taking out the suspension fit now and then will get back to the engine.
The crank bolt is 24 mm but I got the deep socket set as I will need those for the suspension wrenching

alright bro keep us posted up if you get into the engine again
