A lot of ppl put too much thought into bellhousing run out. Never thinking of the flex plate and converter run out. Or flywheel/ clutch runout. Just tightening the converter to the flex plate can pull it outa whack so the converter rubs on the pump bushing. Lots that ppl never think about. Kim
It didn't have a front seal leak, but the pump bushing was scuffed halfway around, enough to catch a fingernail. Oddly the tc didn't have any visible wear. Hadn't considered looking at the flexplate other than for cracks.
I was guessing that the bushing was probably worn due to gravity and the heavy converter and geartrain resting on it during cold starts, plus my valve body doesn't charge the converter in park.
