Still having issues with my GN
I have checked the exhaust headers and have seen that they have been welded up at one time or another, but dont see any new leaks, maybe i should do the gm top clean treatment and see if there are any new leaks?? I can see having to add more fuel to compensate for the exhaust leak.- turbodiesel6_6
