Had an oil pressure sensor snap in a Honda B18C block tonight while driving around. Possibly due to a bump on Interstate 64. It is a pretty standard aftermarket (brass?) fitting for an aftermarket gauge, not OEM piece. Broke right at the outer edge of the block. A thin metal ring clung to the brass also (pic attached). I certainly don't want this to happen again, anyone got a theory as to why it would snap? Pics might have clues:
