    Default olds 455 crank slinger rubbing

    olds 455 crank slinger seems to be rubbing and wearing on timing cover. I pulled the oil pan and timing cover to fix oil leak and slinger seems to have worn a groove on bottom 120deg of timing cover. Cover was brand new on rebuild. I loosely reassembles without Hardin front mount and slinger does not rub. when hardin mount is re-installed it slightly pushes in on timing cover ad slinger rubs. Original gasket was 0.030, now I have a 0.020 so I believe the slinger will wear another 0.010 into cover. Anyone have this problem with the Hardin engine mounts? It does not appeat bent. Should I grind the rear to relieve pressure off the timing cover?
