okay i know i have seen this on here before and cant seem to find it, but how do i search the posts for manifold replacement exhaust leaks etc. i have a 97' 150 4.6 L 4x4 that i recently had to drill out the manifold studs to exhaust flanges due to rusting off of the studs, got that done at home had new magnaflow installed and now have another leak!!! i believe it is now the manifold to head studs on the pass. side rear port!!! i am pissed and want to know who has done this and what the project entailed. i picture major horrors getting at the studs and getting them out.
