So yes, something could go through the turbine as well.

That's not the case with Madwi's unit. The inlet impeller has no FOD marks on it. It's clean. The impeller has rub marks on the sides from contact with the volute. The shaft shows high heat almost to the inlet side bearings. The grease that was on the turbine end has changed to a waxy ash. The grease that was in the inlet side bearings is still good. The turbine side bearings failed from a break down of the grease caused by the high heat generated from the turbine end.
