1982 FJ 60 ..... I had an exhaust leak on my manifold and a really bad one on the EGR . I decided to DeSmog when I changed the exhaust gaskets. Bottom line ....... the DeSmog came out good but I still have a exhaust leak. All new gaskets . Everything torqued to specs. Should I pull the manifolds and have them trued at a machine shop or can I just double the gaskets ??

I would have the manifolds planed/ trued up versus double gasket
did you re-torque several times after heat/cool cycles?

If you get the manifold machined flat, it won’t leak anymore. If you try the thicker gasket idea, it won’t leak for a little bit — but then will leak again.
Trying to fix a leaky manifold with thicker gaskets isn’t the answer.
