So im sure most of you (pre 1997) are familiar with exhaust leaks. Ive been told that Ford didnt put manifold gaskets on from factory and that is the main reason I have the leak. I am looking for the cheapest way to get rid of this problem. Manifolds being $150 a piece I am just wondering if i cold take off my original manifolds and put new copper gaskets in? Let me know if this has worked for you or not? Thanks. 1992 302.
