My jeep had run a few time in 15 years and I had concerns, also. I pulled the engine/transmission-transfer case assemblies out. I rebuilt the transfer case & transmission because they needed it. I removed the head, oil pan, water pump and distributor from the engine block for a visual inspection. The pistons and head had a lot of carbon which was removed with brake clean fluid. I cleaned the head gasket sealing surfaces looking for dings and cracks and also used a straight edge and feeler gage to get an idea of trueness of the head to block sealing surfaces. I also looked into the coolant passage ways to see how much rust had built up over the years of sitting in the shed. There was a lot. In crankshaft area, I used brake clean again to remove the years of carbon built up from the inside of the motor block. I inspected all crankshaft bearings and connecting rod bearings looking for babbit wear points. I also disassembled and cleaned the distributor, reassembled with new points, cap, and wires. Put it all back together, timed it, and started it. Of course this took alot of time. Go slow and be systematic. The jeep is very basic.
I used 6 bottles of O'Reilly best radiator cleaner over 2 month period. The block should have been boiled out.
