ever round out the nut on the oxygen sensor?

I did.

Can't get it off now, borrowed some super duper penetrant and see if that will make it an easy out.......but it's completely rounded off.......****.

Vice grips? I dunno..

Get a pipe wrench on it.

use a torch, then with a pair of large vise grips or channel locks you might be able to turn it.

Yeah he used a pair of vice grips, and that's what rounded it off in the first place.

Dave, if you need a propane torch, I have one if you don't.

propane torch is like drinking "light" beer. Won't do shit. need something hotter or OA torch. then with channel locks or pipe wrench or vise grips reef on it!! should twist out no problem.

hmm, thanks guys

Yeah Jay thanks man I might take you up on the torch, it it doesn't do shit then I'll get something hotter I guess.

Oxy torch and vise grips. Probably won't come off any other way, but don't use it after you heat it up with the torch, it's useless afterwards.

don't use the oxygen sensor after I heat it up? Is that what you meant?

06-17-2009, 06:28 PM
yes, don't re-use the 02 sensor, and don't use a propane torch, it won't do shit. Propane won't get it hot enough. If it's in there really badly, just cut the wire and leave it. put a new hole in the pipe, weld in a new threaded insert and use anti-sieze (the kind that is safe for 02 sensors) and install a new 02.

Heat up the o2 sensor with a torch,propane will work,its not about the heat its actually the cooling that breaks them free. Heat it up and purge right away with really cold water,lock the grips down and get her out. it'll work. Mister

just dont use regular anti sieze on it, it will make it worse, you need the coppercrap.

Pipe wrench wins, everytime. Some call them monkey wrenches. There is no way it won't get it out. ;) Just use more leverage.

06-18-2009, 01:05 PM
+1 for pipe wrench

06-18-2009, 08:08 PM
okay, propane torch, cold water and pipe wrench wins, I'm gonna try that

Thanks Guys

I had the exact same problem, wound up having to take it to my mechanic. I tried heat, pipe wrench (both good ideas, but didn't work for me), vice grips, channel locks, and swearing. Even at the mechanics, it wouldn't come off without (most likely) damaging the manifold, so we left it. Now I'm either looking at replacing the whole manifold, or just that section of pipe, getting the same from a donor car, having a shop flare the pipe on both ends, and then strapping it...

Have them bore a new hole and weld a new bung in beside the old one and call it a day.
