Quite a huge concern for me & possibly the reason I ran the bearings on my motor to begin with. I have done a bit of research & to be honest, much of it is a bit beyond me. This only came up today when I was reading a few random threads. On my car, I am not even sure what pump was originally used before the rebuild, my 5M pump, or the 7M pump that came with the motor. All I know is the mechanic that did the rebuild told me that when he removed the oil pan (5M obviously), it seemed that the bottom end(the strainer portion?) of the pump had been touching the oil pan, because the pan was dented. Then it turned out that the pump itself was scored & needed replacing. I bought another pump, which the spares place called a Jap pump, & I think it was a 7M pump. When we tried to fit it, it was too long, so we took off the bottom half (once again the strainer portion?) of the old pump & fitted it to the new pump, because it was shorter. Problem solved..............or not!!! Looking at the threads I did today & I must confess that I have seen this before, printed it & gave it to the mechanic, it occured to me that this could be the reason for running the bearings!!! I don't know what I have in the car now, & is it absolutely neccessary to cut & rotate the pickup? URGENT feedback PLEASE!!!
