If there were secondary flashovers, there would be no way to know it short
of removing the coil from the oil bath, and being so messy, one would never
do this.  So a sealed coil that did arc internally would be
indistinguishable from a poor performing coil.

Hi,
After reading the latest thread concerning methods to insulate secondary
windings, I was wondering the feasibility of obtaining a piece of  PVC with
an i.d. slightly larger than the o.d. of the secondary winding, slipping the
coil in and filling the gap with mineral or transformer oil, after proper
sealing measures have been taken.  Seems to me that this would eliminate
insulating difficulties and protect the secondary from flashovers.  Thoughts
would be appreciated.
