Sounds like opening the pig, draining some oil into a bucket, and removing the terminal if possable would be a good idea, then sealing it with some hv caulking (for members of the list,would standard clear silicon do?) would help, I would'nt be suprised if the terminals are designed to be under oil on the inside of the transformer and draining them below that point in operation might cause arcover
(Put the oil from the bucket back once your done sealing)

Many I have seen have those bolt on vents. They are usually red or some other odd color to indicate they are there. It would be near to top lip where the air space is. Often they are on a chain with a sold plug to prevent leaking during shipping. One takes out the shipping plug and puts the vent plug it its place.

A lot depends on your particular pig and its maker. Sounds like you need a tiny air vent.

Folks-

I haven't used my pig much, but I finally figured out where it's been leaking from - the top of the bushings!
Oil actually DRIPS off the terminals at the top of bushings, runs over the top, and makes a mess on the floor. I've seen it, but I can't figure out why. Granted, it's getting colder out here in Virginia Beach, but the thing came from Wisconsin and leaked all over the pallet on the way here. I wouldn't think the oil level could still be high enough that thermal effects would squeeze it out.
Can transformer oil creep UP and over a surface? Or is there some capillary action up the internal terminal wiring? Is there some sort of venting/pressure equalization system on the pig that needs to be checked?
