I am thinking I will just go ahead and tear the thing down and check it out, I have seen complete gasket sets on ebay for about $175? What about the piston/liner kits any good sources on those or should I just re-ring it if it is within spec? What else do I need to know, I noticed somewhere that there is a tool for removing the liners? Any help is appreciated. By the way, this is going into my 97 FZJ80. I am about to order the Isuzu diesel Swapper adapter, 700r4 transmission, and a Marks adapter to the transfer case unless someone can talk me into a better way, otherwise I will let everyone know how it goes.

"Old diesel" will not make an engine smoke. The oil it's made from is already several million years old. However if the engine has only been run at low load and not warmed up fully it can smoke until warmed up and the leftover carbon burnt out.
Use only genuine pistons and rings in these engines. The liners are available cheaper aftermarket and are identical IMO. Aftermarket pistons appear identical but my bus mechanic friends tell me they don't last (I"m running some, I'll let you know).
Aftermarket rings and gaskets are absolute crap, do not stray from genuine Isuzu for these.
Check out my comments in the "4BD1T reliability" thread on 4btswaps.com I have some experience in this matter.
I have made up a liner tool before that worked well, I can email you a PDF of the drawing. I would refine the design a little before making another one, but I don't have time to do that for another couple of weeks.
My tool is a profiled plate, it uses a large piece of pipe, 12mm threaded rod, a block of wood and some nuts to pull the liner out.
