85Sub4WD Posted March 6, 2005 Share Posted March 6, 2005 I am in a bit of a pickle - I went to replace my O2 sensor (was running very rich - and seemed the reason for the problem) - had to remove Y-pipe anyway (exhaust leak downstream from sensor) - and I discovered to my disgust that it was rusted to the point of being fused in place (WD40 and 3-in-one had no effect) I actually broke my O2 sensor socket on it :cool: (yes, with my 2' breaking bar - must have been a bad cast) Anyway - I had to use an impact wrench to get it out - and there is not much left of the threads - found that out after I stripped my new O2 sensor on it I looked up the price of a HeliCoil O2 sensor kit - around $100 I don't have any way to get another Y-pipe (save a 4-hour drive). Should I just drag the Y-pipe over to a shop and have them do the HeliCoiling? Any other advice? - it would be appreciated Quote Link to comment Share on other sites More sharing options...
Skip Posted March 6, 2005 Share Posted March 6, 2005 Many places sell the 02 sensor bung. I buy them from NAPA and then weld it onto the turbo down pipes I make. You could grind or with a large drill bit get the old one off and have the new one welded on I think it would be cheaper than a c-note. Just a thought Quote Link to comment Share on other sites More sharing options...
