Did you PRESSURE check the converter? Mine had no visible cracks but 25 - 30psi in the snout and some water around the weld showed a crack that was over 1/2 way around right in the middle of the weld. The firast time I checked I was so sure it was fine that I put a new pump seal and bushing in, moved the vent to the rear, put it all together, tested it, and had to tear it back out again.
