| well i understand that i went with him today and talked to the welder and he said that the aluminum weld would stick for a while but not permanently does that sound right or should we get another opinion i dont ever and have never welded with aluminum so i dont know much about it you said damaging the o2 sensors/cats im assuming this would happen from the coolant ? if thats the case i dont think it would hurt them other wise water/alky injection would be warned against also i know its not the right way nor is it the proper way but he brought up steel weld epoxy which is very similar to jb weld i personally say no the it but would it in theory work if he was forced to go that route til he can afford to have to heads reported and polished and matched ?
