Both O2 sensors crossthreaded from factory

    I was working on installing an atp downpipe and it was really the second worst thing I've ever done while working on a car took me 5 fucking hours to remove the stock downpipe. I digress neither of the two o2 sensors wanted to come loose and I eventually coaxed them by tightening a little the loosening more and on both the threads were badly damaged. My car only has 30k miles and the sensors have never been removed prior. Can I warranty the sensors with ford? Also I need two o2 sensors so if anyone has some let me know.

    I guess no one can help.

    lol.

    I decided to order some o2 sensors from Rock Auto since for $95 I got both shipped to my door compared to $100 for each from the dealer. Still though I feel like Ford did me dirty and it seems I wasn't the only one with this issue.

    Lol at the meme but no, I don't think Ford would ever warranty the removal of a previously good part.

    If you had an O2 sensor problem that they diagnosed and then had a problem removing is one thing but you removing it for upgrading the DP is completely different.

    And fwiw, I had the same issue on mine and had to replace the front as well. Out-of-pocket cost on my end as well. *Use anti-seize!!!*

    Please check with me on parts next time, I could have sold you both sensors for $67.52 for the pair and no more than $10.00 for UPS ground. Assuming you're in the continental U.S.

    And yes, as we discussed the only way to get those sensors warrantied would have been to have it at a dealership but even then they wouldn't have been removing them unless the part had actually failed and it could be a sticky issue trying to explain why you were removing them yourself.

    I paid $30 for overnight shipping included in that $95 that I said. I got a great deal, but I will remember to ask you first next time I need parts!

    Yeah that is what I figured. I will be using anti-seize, then installing it finger tight before using a torque wrench I am not about to buy 2 more when I go BT. I am not hopeful Ford will warranty their labor.

    These probably weren't cross threaded from the factory. Generally, these come out like that due to the heat cycling. At the dealer, I would always heat the bung with a torch or inductive heater until red hot and sometimes even then (<10%), they would strip the threads on the way out. You've got to be sure to run a tap through the bung to clear out any rough spots before reinstalling in the oem pipe.

    The bungs on the original pipe are damaged and will need to be replaced if I ever put it back on. I have never had o2 sensors on the 20+ year old Hondas I used to work on with 130k+ miles come out this way.
