jackso11 Posted August 5, 2011 Share Posted August 5, 2011 Is there a special way this needs to be removed? I can't get mine out as all. The nut seems to undo a few turns then just gets impossible to turn. Anyone in London want to change mine for me Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted August 5, 2011 Share Posted August 5, 2011 (edited) The threads on the studs often gall with the stainless Aerotight nuts Toyota use. I often end up taking the turbo elbow off to drill out studs that are *uggered and still seized in the casting as a double annoyance, after trying to remove seized nuts.

Well.....that sounds like a lot more work than I was expecting to do Might just take it somewhere to get it changed in that case. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted August 6, 2011 Share Posted August 6, 2011 If the nut is locked up on the stud you COULD try a Torx socket on the end of the afflicted stud and see if the whole mess will unscrew from the turbo elbow, and just pop in a new stud with a new nut. You could even use a short (so it doesn't bottom out) M8 bolt, or make a stud from a longer M8 bolt. Quote Link to comment Share on other sites More sharing options...
jackso11 Posted August 17, 2011 Author Share Posted August 17, 2011 I can't get this damn thing out. It turns about 2 turns and then becomes imposible to move. Have they got threadlock on them? I guess not as the heat would just melt it. Don't suppose you know what torx size it is chris? if you do I might be able to get a torx socket on the way home. Anyone around east london want to change it for me? Quote Link to comment Share on other sites More sharing options...
jackso11 Posted August 17, 2011 Author Share Posted August 17, 2011 Just to check, the lambda sensor is located on under the turbos at the back, driver side, on the small elbow that links to where the first cat would be if I had one, right? Only reason I ask is I have been reading posts of people getting them out with long 12mm sockets and I can hardly heven get a ring spanner in there with room to move it around let alone a long socket!

mellonman Posted August 17, 2011 Share Posted August 17, 2011 that is where it is and i used a socket with a wobbly and extention to do mine, try and wire brush the thread to clean it up then soak with wd4o over night,if that fails try taking it out for a good drive and get it really hot and try again with it still being hot(wear gloves) lol Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted August 17, 2011 Share Posted August 17, 2011 As I think I said before, they gall and lock solid. You will almost certainly need to get the whole stud and nut out of the elbow and replace both. Often the only way is to take the elbow off. If you think the nuts for the O2 sensor are hard to get at, just wait until you see, or rather *FEEL* where one of the elbow nuts are Quote Link to comment Share on other sites More sharing options...

Scott Posted August 17, 2011 Share Posted August 17, 2011 Just so that you know, there are 2 that you need to remove If they are "stopping" then you aren't pulling hard enough. You will easily shear the stud before being stopped, unless you have arms of spaghetti Get some plus gas on it, leave it overnight then go for it in the morning. Make sure the spanner you are using is of decent quality so that you don't round it off. Taking off the heatshield should give you much better access. I actually can't think of much being in the way TBH. A little torch will work wonders to see where you are working. I must have been lucky as mine came out no bother. The tubby nuts on the other hand brought just about every stud with them lol. Quote Link to comment Share on other sites More sharing options...

Haha, its my arms that are the problem, by the time I get in there and get hold of the spanner there is no room left to move! I can only hold it and move it about 2 inches before there is no space left. I am going to take all the turbo pipes off and replace with polished ones so maybe I will just wait until I do that, hopefully that will make more room. Plus gas = penetration spray?

p3te Posted August 17, 2011 Share Posted August 17, 2011 i went to change my o2 sensor not long ago and found that the nut was cross threaded on the stud and would only unscrew so far before seizing solid, i hit lucky and the stud actually unscrewed with the nut on it in the end.
