this is why it is always a good idea to clean the INSIDE of the header out with gas or brake cleaner or whatever BEFORE you install it and run it

It looks more like the problem here is that the damn bung is placed in such a way that when the motor torques the sensor hits the crossmember and got bent.

I ran the car sans 02 for the first 100 miles so it definitely wasn't residual oil...
