OK..

No, I'm not sure about if the transformer is designed for 
being filled all up. But I know for sure that some of the 
'substance' has had it's way out.

This because of oil on the paper that I wrapped around 
the beast!

I'm not sure on how much. It could be just a fraction missing
but also could be more than that. Hard to tell..

It's so dark inside that darn thing!! Just a 4 mm drain pipe
(exhaust pipe if boiling starts?)
