Technically it was yesterday, but I did battle with this oxygen sensor in the Crown Vic (see it in its horribly mangled glory in my pics).
While I started work on it last weekend, it proved that I was in need of heavier duty extraction tools. I got them in this week and removed it yesterday morning.
If you can see, whoever installed this failed sensor cross-threaded it into the hole. Which explains the sensor’s battle to remain in the exhaust. Good thing I have a large size tap, and I recut the threads.
This was the only faulty sensor (Bank 2, Sensor 1) on the 4.6.. if this one was done this way, I wonder what the others are like? By the way, it did correct the issue and the car is back to normal operation.
In the process of getting this done, I did notice the engine is not original. The department that owned it at some point had a replacement engine installed, from the label on the valve cover. I saw a similar label on the replacement 5.4 V8 in my Ford van I sold a few years ago.
Too smoky for doing much beyond that, so I went inside.
