Prevention
After work over an exhaust system check, that in connections there was no preliminary tightness and there was a sufficient interval between system and a body. If necessary weaken fixing clips and adjust position of the exhaust silencer and an exhaust pipe, turning and moving them in the longitudinal direction to receive a sufficient interval and evenly to load fixing rings. Always replace everything самоконтрящиеся nuts.

Prevention
The carving of the oxygen sensor is covered with protivozadirochny structure. Do not allow structure to get to sensor cuts.
After work over an exhaust system check, that in connections there was no preliminary tightness and there was a sufficient interval between system and a body. If necessary weaken fixing clips and adjust position of the exhaust silencer and an exhaust pipe, turning and moving them in the longitudinal direction to receive a sufficient interval and evenly to load fixing rings. Always replace everything самоконтрящиеся nuts.
