OK yesterdy I was fixing the niggly pribs with the car. Decided to take it to my m8s garage to get the work done instead of braking it myself using the wrong tools.

 

So I got him to do the tracking and I cleaned out the engine temp sensor. Next on the list Passenger o2 sensor. Everything removed and out of the way, managed to get the o2 sensor moving. When we got it out noticed a wee bit of the thread had ripped. Another mechanic in the garage said, "rushed it too much", I replied "3 hours to loosen a sensor, f**k off". But I knew it was true.

 

Anyway, the way it is fixed in is through an adaptor incase people like me get their hands on it :nono: , so I think I have the folloing options:

 

- Clean out thread and re-tap. Attempt fitting it then if unsuccesful, tap to larger size and use new adaptor.

- Remove existing adaptor and refit new one (assuming I can remove it, about a 32mm size and very thin).

- Buy new bigger turbos (it is the turbo that the adaptor is screwed into isnt it?) and head down to a specialist (I doubt I will do this but I am tempted).

 

What do you guys think. Any recommendations?

 

TIA,

Think the o2 sensors screw into the manifolds mate.

 

Alan......

02 sensor? Lambda sensors should never be cleaned out according to the manufacturers mate!

What do you mean cleaned out?

 

If its in the manifold, its not that big of a deal then. At worst I will just blank the hole off and get the mechanic to refit the o2/lambda sensor someplace else. I have the new one plugged in just now, but I doesnt like running although I managed to get it home. I imagine its cos the ECU thinks its constantly cold now as its just sitting near the battery.

 

Any suggestion?

they screw into a boss which you can get seperatly from nissan. done the same on mine!

The boss looks hard to remove though as it only has a small lip. Did you use any special tools for it. I was thinking of using one like for my road bike handlebars, ie a thin headed spanner, but I imagine as it is into the manifold. Hot, cold, hot, cold, hot, cold = stuck lol. SO I doubt the tool I am talking about would do the job.

 

Do you remember the part no?
