The catalytic converter will burn excess oil – to a point.
Does it smoke at all when started cold?
What is the oil consumption?
What do the sparkplugs look like?
I would do both a cranking compression test and a cylinder leak test.
This will give you a better idea of what is inside.
Please report back.

Valves are properly adjusted.
Oil is Castrol 20w-50
Engine temp on a really hot day will run 230 degrees approx.
Engine does not smoke at all when starting.
Oil consumption is about a qt every 1500 miles or so.
Plugs are white...i.e. on the lean side.
50k miles ago the compression was 171 / 170 across the board.
