Question Possible exhuast leak

I hear a ticking sound coming from under the cab of my 04 Screw 5.4L. Sounds to me like a leaking exhuast manifold gasket, or pipe gasket. Has anyone had any issues or problems with the 5.4L leaking manifold gaskets, and do the exhuast pipes have gaskets in them where they connect at the manifold, or does Ford still use the old ball/socket method like my Mustang does??

BTW, its not the cam-phaser knock...my engine does that too, but very very slightly anymore, thank god. Thanks guys

Do you hear the noises after the engine is off?

No, I dont. And the noise after its shut off, is just the typical noise that exahust systems make when they are cooling off. This is a distinct ticking noise. It sounds EXACTLY like my Mustang does when its leaking a header gasket. It sounds like it is coming from almost right under my driver's door under the truck. Funny thing is....after the truck gets up to operating temperature..the noise suddendly almost completely dissappears. Usually an exhuast leak will leak all the time. Unless, like I am thinking, my manifold gasket is leaking on the drivers side...and when the engine gets up to temperature, the gasket is expanding, and covering its own leak. What do you think??
