It could also be leaking from there but there was a large visible split in the header just before the flange on the passenger side. I could see it through the wheel well haha. There's a local guy selling another one with a little more miles but in leagues better shape for the same price. Only thing making me hesitate is what I would do with the carcass of the truck once I've picked through it. I unfortunately don't have the space to let it sit and I don't want in in the garage longer than it needs to be there.If youre lucky, it could just be the manifold studs in the rear of the heads holding the exhaust manifolds to the heads are just broken. Its SUPER common. When you go to put your new manifolds on definitely use the ARP bolts
