4 pirelli run flats on BMW X3. What fun those are to dismount and mount new ones.
I’m curious as to why anyone would shoot at anyone else in a vehicleWent over to a customers house to look at their 2008 Ford Edge.... someone shot at them last night with what looks like a .22. a hole in the grill, core support, radiator, and valve cover. Another hole in the left headlight. They were driving home and got fired on by an approaching truck when they met. I was so surprised I didn't think to take pictures, but they got plenty. If I end up fixing it I'll get some pictures.
No luck in budging the O2 sensor, or I should say, I don't want to break something else. But I don't think that's the issue--I thought I heard a leak yesterday, and so while it was up I fired up. Yep, right after the cat (but before the O2) I felt plenty of breeze. On the good side it felt like it plugged itself up while running? not sure if self sealing or coming off high idle.About to crawl under the car and loosen the O2 sensor. It decided to toss a P0420 code last night. BUT as it’s over 20 years old I don’t have to actually repair it. But… not sure I want to look at the CEL going forward, just in case it tosses a code for something else. So I’m thinking of trying out some spacers to see if that “fixes” the issue.
I'm skeptical that a leak after the cat would cause your efficiency code, but it'd be nice to fix the leak either way....No luck in budging the O2 sensor, or I should say, I don't want to break something else.

Wonder if exhaust cement will fix? Otherwise off to the shop I guess, I don't do exhaust work if I can avoid it (maybe this would not be too bad, just sawzall the bolts and replace everything after the cat?).

A bit bummed, as I think I replaced that O2 maybe 5 years ago? pretty sure I used the anti-seize on it. So it shouldn’t be stuck—shouldn’t be.I'm skeptical that a leak after the cat would cause your efficiency code, but it'd be nice to fix the leak either way....
Fake MAPP gas or an LP torch to the bung will almost surely allow you to get the sensor out if you're using the appropriate socket and enough leverage
edit: if you ever see old school bottles of MAPP circa '08 or earlier at that flea market, hoarde them!!
Got under it, and I grab the exhaust, give a wiggle, and it looks loose to me. I'm starting to wonder if something literally rotted away here, like the entire bracket that holds the work together.I thought about wrenching on it, as it should come out. Thing is, if I have an exhaust leak nearby, and i really torque on this, is there a chance I might open up that leak worse? Granted, the leak needs repair; a bubblegum repair is not going to last for very long. But would I rather not open up the crack (or whatever it is), try some cement, and go from there?
I hate run flats so much. First thing I did when I got my BMW was ditch the stupid run flats for some proper tires and it greatly improved the ride quality.4 pirelli run flats on BMW X3. What fun those are to dismount and mount new ones.
