exhaust pressure sensing tube
Hi guys, I am changing exhaust manifold gaskets and run into a problem. I was not able to unscrew exhaust pressure sensing tube from both manifold and exhaust pressure sensing housing. After heating tube unscrewed from the housing but not from manifold. I left it hanging there. So , I changed gaskets, bolts , etc and now I think I have damaged threads in the housing. Anybody knows what to do? Maybe you know what kind of thread it is? I do not know for sure but it looks to me metric M12 1.0 . Thanks!

When I changed mine ,I ended up having to cut the type to put a socket on it .
Then I just bought a new one .

When they are stuck like that, cut the pipe part off it then take your time heating it up until the whole fitting is glowing a nice dull red on its own... use a 6-point socket on it, work it back and fourth a little at a time until it comes out.

RE: exhaust pressure sensing tube
same here. mine was so rusted in place that it was bending my open ended wrench trying to turn it. eventually ordered a new pipe then cut the old one and threw a socket on there. didn't need heat, just broke it free and it came right out.

Line wrenches are handy for this.
