I'd check and see if there is an exhaust some where before your o2. I had a pin hole leak, which I couldn't find do the mounted location, and I went through three o2 sensors before I found it. This was over a one year period.
Have a look just to make sure. The leak was between the header (y-pipe) gasket and engine block.
