Re: 97 expedition exhaust leak
Yeah, the manifold definately isn't coming off... all of the top studs have the nuts rounded off. They are rusted on so bad the nut became part of the manifold itself.
The lower nuts, i'm not even gonna talk about them. There is no way in hell to get on them, even with a universal, the frame of the truck sits literally right in front of the nuts.
Whatever he did, when he broke the original flanges nuts, instead of drilling them out, he just took this compression type round thing that locks into itself on both sides, and he put a u bolt on one side, and a bolt through into the y-pipe flange on the other side. It was only tightening down on one side, leaving the other side able to be opened. Now I have to find a way to get the original bolts OFF, since the manifold isn't going to come off, obv... this is aggravating as hell, a simple job that has taken me 6 hours and i've made NO progress other than getting the tire off.
EDIT: After looking, I can't drill out the manifold. On the right side, there is a thick lip on the bottom stud that prevents you from drilling it from the other side.. looks like I am going to have to find a way to get the nuts out from the manifold itself and put new studs in there... do they just screw in with a nut on the other side?
