I agree with Brock on this one. While it is extremely rare for frost plugs to leak, they can occasionally.
I would try the O-rings first, it's much more likely to be the culprit.
Typical frost plug leaks happen on old vehicles where the chemical content is not properly maintained and they rot out, which takes quite some time.
