You can inspect the condition using an endoscope without removing the intake plenum (see photos).

You will, however, eliminate the possibility of the “killer bolt” issue by removing it.

I live in Alaska, and if you get stationed here, you will want a functional grid heater.

I hope this information helps with your decision.
