I just experienced an interesting situation that relates here. I feel like I keep a good eye on the
oil pressure, but I'm glad that I have the stronger driveshaft in my pump. I was driving and the car quit all of a sudden. What had happened is that the
oil pump had some debris enter the gerotor and create "tight" spots as it rotated. This caused extra load between the distributor gear and the pump which sheared the rollpin in the gear. All the pieces stayed in the gear, it just spun on the shaft. I feel lucky because if the driveshaft had twisted or sheared to the point that the
oil pump stopped, I might not have noticed no oil pressure before it was too late. I like the fact that the engine quit along with the oil pump.... A new pump and rollpin and I'm on my way.
