I changed out the o2 sensor on my 04 ram yesterday and it took all the strength I could muster to get it out. When it came out it brought most of the bung threads with it. So I was able to get the new o2 sensor threaded in but the damaged bung threads damaged the new o2 sensor threads. Then i went to the part store and they recommended this stuff

So I used it and everything's seems fine. There are 2 unknowns left however, at least that I can think of. 1. I've got the 5.7 hemi in my truck. Can this stuff take the heat from a v8. And 2. From what Ive read about these types of products they're not always as permanent as they claim to be. And I dont want to be out there fixing it all the time. So any one know if it will last holding the o2 sensor in? Thanks
