    stripped threads in exhaust manifold for O2 sensor

    The O2 sensor for my wideband went bad couple weeks ago. went to replace it today and found the sensor loose. figured it had just back out. got a replacement sensor and discovered the threads in the mani are striped. sensor goes in all the way to the washer with no bite. going to start pulling the manifold now. anyone got any ideas on how to possibly save the manifold? 08+ style manifold

    Take the washer off...probably buy you some time. Just don't wrench it till it strips again. My threads weren't great when I did mine. In retro spec I would've had a machine shop do it. They have the equipment to not have the bit wobble. Also the threads just aren't that deep on the sensor. When I take my manifold off again I'll have it milled in that spot and I'll probably be fine.

    I had one do this before and I just took a file and filed it down so it would have new threads to bite.

    what do you guys think about removing the washer to get the first thread to bite and epoxy/jb weld the rest of the threads in? think that will hold?

    I thought about this. but didn't know if the sensor had to be so far away from the stream.

    Yikes not sure I'd about expoxy it in. Mine was popping out...took washer off....now carry a modified crescent wrench...never popped out since I took washer off. Just snug it in should be fine..unless your threads are real loose

    Seen people take some metal off the top of the manifold.
    If you take off 1/8" maybe you can get into some good threads.
