That's a load of rubbish, either it was seated (fitted correctly), or it wasn't.
That does NOT happen gradually, that is a sudden catastrophic failure.
And if you don't find the cause, the next pushrod will also jump out.
For 1 out 16 to do that, I would still be looking at everything to do with how that valve operates. And during that, you may find more things wrong.
