Just put my #1 TO30 back together, had the inner thrust bearing decide to come apart. Minimal wear on the bearings themselves, but I have always had a low oil pressure issue with this motor. Rebuilt the pump again and still same problem. Above idle hold just over 10 psi and drops to near 0 at idle. Checked with my pressure test gauge and reads a little higher but that's it. I read in the archives that the pump itself may be worn and have found one on fleabay to rebuild and try. Just looking for any other direction to go besides this. Other pumps that I have rebuilt all hold good pressure. Thanks
