I recently replaced the O2 sensor, and about a week ago I heard a rattle. The nuts holding the sensor had worked themselves loose. I went to tighten them again and bent one of the studs and broke the other.Soaked them in PB blaster for 2 days, then I tried an EZ out. Now I have an ez out broken off inside one of them and the other is broken off as well.

Think if I just run a sturdy hose clamp on either side of the flange where the studs used to be it would hold it in? Other suggestions?
