As I suspected, the Plenum gasket has been sucked into the runner, leaving a gap between the IH and Plenum. You can see in the photo...
What a horrible thought to have a piece of solid brittle gasket be sucked in and break loose. What would a valve do with such a piece?

Since I didn't, I guess it became loose and managed to suck itself inwards over time.

If this happens a third time - I think I will give up on gaskets and go with Scotts rubber gaskets.
A solid rubber gasket on the plenum stays flexible and puts pressure
on both surfaces, hot or cold. I just checked my bolts, nice and tight.
A rubber gasket on the plenum works well because the temp there does not get so frigging hot.
Other locations would not fare so well.
