Rmoving oil inside objective

Does anyone know of methods for removing immersion oil from inside an
objective? I have a high quality Nikon PlanApo 60/1.4 that has
accumulated internal oil after years of use on an inverted scope.
After determining the cost and schedule of repair by Nikon, we opted to
replace the original objective with a used one. I still have the
contaminated objective, and would like to try cleaning it in-house if
there's a reasonable approach. It seems to me that if oil can get in,
so can a much lower vicosity solvent. I'm considering cycling solvent
in and out by the alternate appilaction of positive and negative
pressure, followed by drying in a warm oven. Does this seem
reasonable? Ant other Ideas? I haven't seriously considered
disassembly, since I have know idea how to do it and I'm afraid
accurate reassembly would be extremely dificult.

Thanks!

Jon
