Oxygen sensor replacement?

1990, GMC, K1500, 4.3L, 151,000 miles. The oxygen sensor is in the tail of the crossover pipe. When I went to change it the sensor was broke off at the above the nut. I let the truck run to heat up the pipe and I couldn't move the sensor. I then heated the thread area and got it good and red hot still it wouldn't turn. I did this two or three more times until the nipple started to break out of the pipe. The thing I would like to know can I get another nipple to weld in or do I have to get a new crossover pipe? If I take the nipple out I don't think it will be possible to get the sensor out.

Once they are corroded in like that, they get fused to the pipe and then there is no saving it. I'm afraid replacing the pipe is going to be the only savior now. Be sure to put anti seize on the sensor threads to avoid this happening again.

Generous Motors at its best! We had the audacity to bail them out with borrowed money at that!

Don't blame GM. It happens to all of them. The combination of corrosion and heat just welds the 2 parts together.

Agree. Especially if the joker before you didn't use anti-sieze. I've been pretty sucessful using a 3/8 impact. Not strong enough to break it, but the hammering (no pun intended) effect usually works.

USA put a man on the moon in 1969 and can't deal with an o2 sensor! Right. GM designed the lunar landing module the was wire mesh wheeled and it's four wheel drive failed! Nice flicking company! 100 bazillion bucks to do that and their equipment fails!
No sympathy for GM from me!

Last I heard, I think they said the lunar rover should still be operable. May have to call in AAA to get it hauled in 4 repair but it's supposed to run- still. I have been pro G M products since the 60's, when it still belonged to G M, and they had design, every year. Not the cookie cutter cars they evolved into. I went to the tech center for many classes, very good training, hands on with newest cars. These days my yard has a diversified collection, albeit still mostly G M, I do/have had many Fords & Chrysler products. Some of the best Fords IMO are still the Model A's. Had many, want another. Basic car- points, condensor, one of the first to employ ignition systems that lasted decades. And how old are YOU??

CH; I can't tell you how old Tom G is, but he was involved in the think tank inventing dirt.

Thinking about it, if T was on the panel to invent dirt, was he standing on water then?

There should be no "ouch" to it, all meant in good humor.
