Believe it or not...
There is a method to putting a transmission onto an engine. I know many of us just slap that sucker in there, bolt it up and go....but there is some centering and measuring.
Perhaps this case, something was pushing against the crank which caused some kind of wear or something was misaligned pulling the flywheel back, which pulled on the crank.
I still can't figure how you don't have oil pressure.

I would not rely on internet forums for advice, you will very rarely find professional mechanics with real experience taking the time to get involved with this kind of discussion. Conversely you will find many keyboard experts who in real terms know everything and nothing.
Odd that they (Turner) didn't catch the 3rd main bearing (thrust bearing) being out of the engine, while checking movement...being the experts and all.

Just goes to show you how little Brits understand about Americans...we live, breath this crap...and participate in plenty of boards...experts, gurus and novices alike. Like to see him say something like this over on Rennlist.
Anyhow, just about "played out" as expected. I'd pull the engine and go through it...or have someone that really knows something about these motors...like D&D fabricating in Almont, Michigan.
Good luck, with whatever direction you proceed.

Correct, installation procedures are critical. And this is the "gray" area of the discussion...none of us were there, are there or will be there, and are only looking at pictures. Personally, if the auto trans was mounted up incorrectly...I'd think/believe that there would have been issues with the trans performance also. But, that's just a notion.

Who knew?
I find it hard to belive an engine expert can know a transmission is to blame...yet know nothing about transmissions.

Hear, hear!
The trans ruined the engine, yet there's nothing wrong with the trans.
Apparently 2+2=5

In this case it may have just did some wear to the bearings...
Aside from operating properly..
Maybe there is something wrong with the trans. Just because it "shifts" supposedly normal to the feel, does NOT mean its not wearing prematurely or have leaking seals or on its way out.
It technically "could" be installs and binding.
and again, SHELF THAT ENGINE AND LOOK FOR SOMETHING DIFFERENT.

Yeah, that's me. Oil pressure light + diesel sounds + misfire, of course my first thought should have been an improperly installed transmission putting force on the crankshaft!

Which would tell me the torque converter is installed wrong. But, I've never seen or heard of one improperly installed that otherwise performed correctly.
I would take the engine apart and measure everything before I ever considered a transmission problem.
