    Check the nuts on the exhaust flange. Brass nuts are used so that they don't corrode and get impossible to remove. They work so well that the engine vibration can loosen them easily as the pipe moves sideways against the manifold. Be sure you have two nuts on each stud and lock the outer one against the other to keep them from unwinding. Vibration will always loosen a nut, never tighten it!

    Also, for a minor warpage issue, a little high heat silicone on both sides of the gasket will help. There is no issue with sensors being damaged, so don't be afraid of a little "glue". Used it for many, many years while working in the trade.

    Sometimes using more than one gasket on the flange solves the problem.

    I agree too, that the car should use a flat gasket, not the donut type.

    ask for one for a '67 Caddy.

    I had to replace a manifold on my car because that mating surface was so far out of true that the gasket wouldn't work. If you can pull the studs without breaking them you might want to have this surfaced, or just buy a NOS manifold from SASCO.

    Well, I can envision a "Donut" style gasket working to a degree, but it's not what is supposed to be there. Besides, the way I envision it, that donut would effectively reduce the diameter of the outlet. Not something that would help performance.[}]

    Miscreant at large.

    exhaust leak

    I developed a leak in my silver hawk at the flange. Took it to the shop where the gasket was replaced by a donut type thing. Ten days later the leak is back! Any ideas on why this would reoccur?
