Thanks Blue, I appreciate your help.
That is strange. Also, the fact that I never noticed it before, and that it was not painted in the process makes me think there was at least a plug or screw in the hole. If this is where oil cooler line entered the engine, doesn't that mean that the hole will allow debris into the engine if not plugged?
