Rebuild was $1800 delivered to my door, no core required. I put about 100 miles on the new engine yesterday without issue, of course I checked compulsively and didn't see any smoke (except from the transmission fluid I managed to spill all over the exhaust). FWIW, the rebuilder said to ignore the oil cap and run 5w-30, so that's what I put in.

lots ot toyotas around that year had similar issue with oil consumption.
No core required, the old engine is sitting in my garage as I'm not sure what to do with it. If curiosity does get the better of me and I end up taking it apart, it won't be for a while, as I have lots of other things lined up that need doing first.

Try some high mileage oil if you haven't already. My Mustang would leak a few drops on the ground every time it sat, I switched to the cheap high mileage Supertech and within 1,000 miles there were no more drops. Been that way for months now.
Either way, beyond using a HM oil I wouldn't worry about a quart per 5k especially on a car that old.

Hopefully the OP's replacement engine goes the distance.
At least the issues with this engine are well known at this point, and there are revised pistons and head bolts that are supposed to correct the flaws (which I confirmed the rebuilder used). It was still driveable with the old motor, but getting to the point where I was adding about half a quart of oil every time I filled the tank, and it's due for smog next month which it absolutely would not pass while emitting visible smoke
