@ Motorgeek--Keeping in mind I know nothing about this bottom end--that is, why it ended up in boxes--top end one box, bottom in another, I'm assuming you too would recommend tearing down the bottom end. (If you can't tell, this is something I'd prefer to avoid, but am willing to tackle it) Assuming that's the case, besides for looking for debris, are there any other things in general you'd inspect? Finally, as for the boring and resleeving. It seems you do that. If you'd like to shoot me a price via PM, I'd be glad to have a look. I prefer to use someone from the LT brotherhood rather than leave this to chance! Thanks.
I would recommend tearing it down. Inspect the cases carefully in the region next to the outside of the crank. There is not much clearance between the cases and crank and the cases are easily damaged when pieces of sleeve or piston skirts pass through this tight area. It is not uncommon for the cases to crack or distort enough to cause an air leak or suck oil from the transmission.
