Anyway thoughts on why all of a sudden he’d end up with .010 clearance ?

I think some signals got crossed here. Nothing is .010 clearance.

When I assembled the engine the #5 crank journal clearance measured .0035 while #1-#4 bearing clearances were .0024-.0025. I used a different bearing shell to get #5 to .0025. As far as I know, none of the clearances have changed.

I was pointing this out because it could indicate a problem with the line bore that I band aided with a different bearing.

I honestly have never seen a rear main seal do that. Was the drag on the crank excessive? After you dropped the crank in etc, did you check how much drag there was?
.

I used red assembly lube on the seal when I installed it, as the instructions say. Nothing seemed out of the ordinary with crank drag.

I may send a few pics to Best Gasket and see if they have anything to say. I'm sure they've seen it before. I'll still get the crank checked just in case.
