the nut on the pipe that goes from the manifold to the egr valve nicely hidden round back of engine as come loose(egr end of pipe, round back of engine, no access etc) obviously its blowing running crap and emitting carbon monoxide into car! ive had it done up from underneath twice but keeps coming loose, mainly cause you cant torque it up properly because of access. anyone had same prob, whats least labour intensive way to get access to it to do the job properly and would it be a good idea to weld the little ******* on lol?

remove all egr systym,might be easier with engine out :D

 

how about a bit of threadlock on the nut once that stuff sets its almost as strong as the metal if you can reach,would be a good temp fix,until you have the oportunaty to remove egr completly,another systym nissan didnt need :xxx:

have been told to remove valve completly but this will make car run 5% richer, its easy to remove just stick a bolt in the manifold and take the connector off the solenoid for the valve. however i want to keep it as was intended cause dont wanna mess bout with fueling. will try some thread lock as you say, if can get to it lol, if i had gearbox removed should be able to get to it properly?
