czakky Posted August 14, 2016 Share Posted August 14, 2016 Does anybody know the size of the bung in the header pipes on an 02? Looking to use a gas analyzer looks like the standard O2 probe is 12mm... Link to comment Share on other sites More sharing options...
Kiwi_Roy Posted August 14, 2016 Share Posted August 14, 2016 I think the bung you are talking about is too small. I had mine welded into the crossover, when not in use I replace it with a sensor from an auto wrecker. Link to comment Share on other sites More sharing options...
docc Posted August 14, 2016 Share Posted August 14, 2016 You can't just take it out and measure it? Link to comment Share on other sites More sharing options...
czakky Posted August 14, 2016 Author Share Posted August 14, 2016 I gave it a half-hearted try and i couldn't get it to budge so I thought I'd ask the experts over here before getting a little bit more serious. Link to comment Share on other sites More sharing options...
docc Posted August 14, 2016 Share Posted August 14, 2016 When Andy York went to test my Exhaust gas, I freaked because the dealer had told me he wouldn't take those out because they strip the header threads. Andy said, "not likely," and just unscrewed them. The Sport had almost 58,000 miles on it then. That said, I would be inclined to use a little heat around them and maybe some penetrating oil (ATF and acteone mix/ "Ed's Red") Link to comment Share on other sites More sharing options...
