that's what I first thought when the oil started spreading across the surface. But far more oil dripped from it than could fit in those tapped holes even if they were full of oil. it wasn't at all oily to the touch before I started heating it.

I doubt it, for one it really isn't a bearing surface. It's a loose fit until the set screws are tightened. there's no reason for this to be an oilite material.
It could be a sintered metal, maybe soaked up so much oil as a side effect of that process, but then why are there such big corner reliefs on the inside, if the whole part was sintered they wouldn't need to mill the inside.

Maybe tomorrow I'll keep heating it and see how much oil comes out.
