You obviously haven't had to remove a lambda probe that's welded itself into the exhaust system before.

 

Snip the wire, use a deep 22mm impact socket on a long bar and replace the sensor, tightening it into place with a ring spanner or a split socket.

 

You can't successfully clean the old one because the heater element has usually failed rendering the old probe useless.

You know what you were saying about probes welding themselves on guess what 😒

really struggling with this n02 sensor it did about half a turn now its gone solid im worried its going to snap the thread off and tips please ???

Heat it with a blowtorch, then try. Back and forth, back and forth.

Got you will try that ive stripped all the inlet manifold etc off to get decent access to it as its in such a chit place you cant get leverage on it.

Ok so this is the latest about a month after I swapped the 02 sensor I had a complete new exhaust system put on now ive finally got the 02 sensor off to reveal that when the exhaust was installed they must have cross threaded and butchered the 02 sensor on.

Its come off now with the blow torch and there is no thread on the old 02 sensor but it had also damaged the thread on the exhaust pipe at the start so I cannot thread the new 02 sensor back on.

Is there anyway this can be tapped to restart the thread and if so what size tap would be needed please or is it a case of a new section of exhaust needed which I dont want to do as its a big section with the flexi piece and cat as well 😞

M18 x 1.5mm usually, I think. Put a vernier across the new one's thread to check the OD is about 18.

 

Cheers wino will check that now thanks

If for some reason you can't recut the thread all is not lost as you can buy a new nut boss.

 

On installing the new sensor make sure it has anti-seize on the threads, many come with it applied and clean the socket the electric connector is to go into and apply your choice of protective "grease" to both sides of the connection (I favour Contralube 770 applied with a small cheap artist's brush).  Make sure any cable supports that were there from new are used or replaced if missing.

 

There are many specialist exhaust places that take more care than the usual bash merchants so are worth seeking out.

 

M18 x 1.5 is what comes up, so I think Wino has it again but as he's put always check.

Yes you are indeed correct wino as always lol  and thanks nta worst part is the garage that did the exhaust has now shut so I cant even go and have a pop lol but live and learn hence why I tend to do everything myself now but at the time I did not have the free time to do it live and learn I guess.

And just to totally kick me in the happy sack they have sent the wrong 02 sensor 👿

I only started redoing stuff on my car because of so many ****-ups by the professionals and "specialist experts" I thought if I'm going to employ an idiot it might as well be me but I really l - o - a - t - h -e working on our cars.  I don't have a garage or many of the tools and certainly not the will, attitude, aptitude, patience, enough physical strength or condition. 

 

Made me laugh when Wino put check with a Vernier, plastic ruler and magnifying glass more like.  😄

 

A crowsfoot type sensor socket might help with removal next time but just use a spanner for installation this time as that way you're less likely to overtighten (short lever to tighten, long to loosen).

 

Do check which part is wrong, fitted or new and that you ordered the correct part, we all make mistakes, I've just got the refund from ordering a set of road springs to discover at delivery I'd ordered a single spring - who fits a single spring!  (most it would appear).

 

Lol like me when I did the front suspension a while back and they had sent the incorrect front springs I should have checked did not and rebuilt it all only for the front end to look like it was a swamp buggy off roader lol :P

Very kind but I'd never be able to trust that even if it was fine.  ETA: I'd no idea you could get them that cheap though.

 

I was lent a Mitutoyo digital but it didn't reset as it should so I checked the manufacturer's website and had already tried the fix they showed and wondered about replacing the battery for a/the(?) specified make but didn't as I didn't think the act would be appreciated.  A person that sells them suggested that it might have been a fake which I doubt.  I doubled it up by using an old manual one a neighbour lent but the drop bar probe thing was bent and despite cleaning and lubing and gentle bending it still had a slight kink.  If my eyes were better I could have just used a bit of wire and measured it. 😉

Not sure what you mean by a new nut boss. The threaded bit is welded to the frontpipe, so if cutting the thread doesn't work, surely a new front pipe is needed? Unless you mean weld a new nut boss in?

Yeah I wondered that as well what was meant.

Boss I think that's the word, nut to get where I mean.

 

Imagine if you went in to a proper exhaust place where they custom make and fit an exhaust to your car, not as expensive as you might think, especially if you're keeping the car a long time, in stainless steel perhaps.

 

But in this case you replace the existing boss with a new one in mild steel (stainless takes more expertise).

 

Below is just an example. - https://www.ebay.co.uk/itm/251317510602

Mate by the time you've taken exhaust off and cut out the old thread the exhaust would be trashed that's beyond feasible to cut it out and replace.

I must be unfeasible then as its the sort of job I have done without a second thought all of my life.

Yeah that's fine if you have a welder etc but no garage is going to want to strip off a 2 year old mild steel exhaust pipe to cut out an 02 thread and weld in a new one I guarantee they will say its not feasible that would be a home job with a welder etc which I don't possess or have the skill set to do.

For (proper?) exhaust places and people like J.R. it's standard fare.

 

I was going to put a post (one of my stock usual's) about using a good penetrating/ releasing fluid (like PluGas, not WD-40 Multi-use) plus patience, time and technique but I thought you were had a time constraint and it might not have worked if the fitting was previously buggered (yes I know some technical terms).

 

This video covers what's gone on and possibly needed here, and the mention the time and patience method, which he didn't do to his regret, if you watch it through you'll see all this is is well worn paths. The title is a bit of a misnomer but not totally. -
