   That problem with the oil swelling up the poly has turned out to be a
minor one compared to a new situation that has cropped up. The plastic
casing has developed a leak! Now I'll have to retank the cap. I'm in the
process of building a wooden tank to put the whole thing into plastic
tank, cap and all. The wooden tank will be coated inside with epoxy
resin to prevent leaks. 
  This has been the most problem prone capacitor I have ever built!
Anything that could go wrong did! Thank you, and all of the list members
for your help. This cap has been pure Hell.
