What gasket would more likely need replacement if it is causing loudness? on 1999 Ford F-150

The noise problem is always; however, is at its loudest when the engine is cold.

more than likely it's an exhaust manifold gasket, the reason it gets quieter when warm is because heat expands the metal and closes the gap. Normaly they sound like a ticking. The exhaust manifold can be cracked also, or the bolts loose. good luck

Thank you for your help. It sounds like the problem except I don't hear the ticking. It is just really, really loud! I have put it off for a long time, but it is so loud I will have to take to have repaired. Just hope it's not too expensive. Have a great day, and I appreciate your time. Sincerely, Christine
