Hi, what signs did your engine give that told you the oil pump went out? On my car, a few times while driving at high speeds, the connector that goes on to the oil pressure sending gauge slipped off and the oil pressure went to zero on the gauge. When this happened, I thought the oil pump went out too, but it was just the wire to the sending unit. The problem is that the wire connector is plastic and the sending unit is very close to the headers. The plastic tends to get baked by the heat, which hardens it. This hard plastic combined with any oil made it difficult for it to stay on, especially at high speeds!
I raise this issue because it is pretty difficult to catch a broken pump before the engine lets you know in a big way that it is broken. I speak from experience, unfortunatly.
