What does the oil do to damage the coils?

Some people say the oil shorts the coil and damages it. I found that the coil I had bad was a dry one, even though I had plug wells that had oil in them also. The oil could produce lower resistance to ground, shorting the coil out, I suppose. I think most people are just in the habit of saying that the oil destroys the coils. I personally believe that they are a bad design and go bad on their own also.

yeah it could go either way.

Oil does not conduct electricity, it can't "short out " anything. Oil is used as an insulator in high voltage transformers.

Correct, and one reason I go the route of the coils being a bad design, but you never know what else might be in that engine oil. :) I used to play with Tesla coils years ago and it is amazing at what insulators become conductors at high voltage also.
