Well I snagged a couple of these sensors off of ebay, looks like they are used factory takeout's. GM had a recall on these and swapped them out, I'm betting the ones being sold off of ebay are takeouts off of brand new trucks on the lot. Mine have a small amount off soot inside one, antiseize on the threads, and appear like they were tightened at once.
Maybe GM read this thread and realized that they were going to fail in the Duramaxs too lol. At least they got out in front of the problem unlike AC.
