I did shave down a three wire CTS to fit into an oil pan drain plug. Then someone else did it and ran out of metal? Look up the Oil Temp Sensor in drain plug thread...
If it fails just plug the hole and add an IAT...

From now on if I intend to try and rethread sensors, I'm going to have a junkyard spare to practice on first. As Mark mentioned, the three wire (brass) sensor in question was too thin ABOVE the threads. I tried the same on a two wire CTS, and it turned out to be steel with a brass core, and solid all the way through. I have another CTS, same application, and it is brass. But I had that one turned on a lathe and it didn't snap like the three wire. Just be careful.
If I wasn't worried about leakage/sealing (pipe thread) then I'd ONLY cut the sensor down where there are threads, no further up the body. Still won't guarantee it doesn't twist off, but the portion of the body where there are threads on the one that broke, was thicker than the portion above the threads.
"Frankentruck" is a "1985" K5, TPI 350 '165/6E (Vortec Heads, SDPC2000 base, roller cam, headers), 32 Spline SM465, 205 w/VSS, 10b/14SF, 3.42's and 33" tires. Soon to be boxed frame, '87 sheetmetal, and TPI w/ '727
I will be running $8D, witch is set up for a intake mounted MAT.
I remember the thread about the oil temp sensors. This one I only need the threaded part re threaded. I just wanted to know if there was any already avalable with the correct thread size before I have one machined. I will drop this one off at the machine shop and see what they can do. If it gets distroyed, then I'm only out $18 for another sensor.
I will only swap to a IAT if there is no other options, as the ecm/bin will be expecting a MAT, not a IAT. Like you said, different temps between the two.

Just chuck up the sensor end in drill mounted in vise and spin it, use a file to shave it, get close to diameter and thread it with die. I did that one in 20 minutes or so and never done it before.

i may be a machinist, but if i can avoid potentially scrapping good parts, i avoid it.
as long as you could hold the two sensors in identical conditions(let's say throw them in a pot of water of something?), then just need to get the sensors around to a calibration point(there are 17), see what temperature the GM sensor is showing, then switch to the Jeep sensor and move the value at that portion of the table around until it matches what the GM sensor was showing. maybe switch back and forth again to confirm it's still the same.
obviously, this is done much easier with an emulator or at least a bank switch.
Why has no one suggested drilling the intake for the larger thread? That's what I do in a situation like this.
The man who says something is impossible, is usually interrupted by the man doing it.
Wow, that can be done?
I would have no clue how to do it. Only problem I see, is finding a controlled environment to put the sensors in to get proper readings from them. Would the ADX also have to be changed?
I would also rather mod a $18 sensor than the intake on my jeep. So no drilling it. I might give what mark said a try, though I dont have any type of drill that will hold this thing.
