Specific TV engine question
My van is burning oil because of rings. It is slowly getting worse. I am now burning 1qt per two tanks of gas. It is too big a job and too expensive and not worth it to me to fix it at this point. Wha...

It only smokes when I first start it. After just a minute or two it stops. No residue on the fender or exhaust. Does that she'd more light?
I suspect the issue is bad valve guide seals not rings. Here is one way to check.
with the car in park give the throttle a good blip and raise the rev's to 3000 rpm or so. then foot off the throttle quick. If you see smoke when you back off the throttle, that indicates valve guides/seals. if you see smoke as you hit the throttle and it continues, and none when you back off the throttle, then rings.
if you see it under both, well, then it is likely rings and valve guides.
it sounds like it's valve guide(s) especiall one cylinder.
Good news is that usually is relatively easy and inexpensive to fix if it is just the seal. if the guide is gone, then more expensive needing to likely remove the head.
A good mechanic can figure out exactly what it is
BTW, chevy small blocks at least through the early 90's were known for having the valve guide seals get brittle and allow some smoking, usually not anywhere near what yours is. but it could be one cylinder is the culprint and has a seal that has gotten brittle enough to crack and allow lots of oil in.
