Unless the oil was over 240F for extended periods (you probably haven't had
that opportunity yet), you are probably fine.  As best I recall, the damage
is somewhat dependent on how hot and long the rotor stays hot.  The first
causality is generally those hard "rubber" inserts that go in the corner
seals - they actually disappear.  The lack of them generally make starting
harder.  Then I think the apex seal starts to "chatter" against the housing
apparently due to deterioration of the oil film due to heat.

But, unless you are noticing hard to start or a power loss you are probably
OK
