You must realize that you have two separate issues.

You have confirmed that it has oil pressure of 2.0 at idle.
Therefore, it is extremely unlikely that you damaged the bearings to a point where additional clearance is now present.

So, the issue is to get it started again. I have a suspicion that the WVO is playing a part in this. See if you can get a can of diesel fuel and attempt to prime the system with diesel fuel. Then get it running properly on diesel fuel.

You can't make any determination on the condition of the engine until it is running again. And, we already know that it will run.
