help! Ticking noise!

[Snakes]

I own a 2004 Titan KC, when the truck is cold and i start it up, a real dominent ticking noise occurs, it will last until the truck warms up. I was thinking its a worn out bushing in the exuast somewhere, but it sounds like its coming out of the oil pan, has anyone had this same problem? I dont want to take it into nissan and get charged out of the yingyang for a problem that i can fix myself! any suggestions?

manifold leak maybe

Titans are known to have noisy fuel injectors, mine are definitely pretty noisy when the engine and ambient temps are cold. Quite noticeable inside while idling at a stop light or pulling out of the garage.

I posted up an audio clip a while back of the noise, let me see if I can find it and you can see if it's the same sound you hear.

Could also be a leak in the exhaust manifold, these are also common and get less noisy once warmed up.

Could be exhaust manifold crack, as it quits when warmed up.
Injector tick keeps on ticking after warm up.

FWIW, my injectors quiet down once the engine warms up and they are definitely noisier with a cold engine in "cold" weather. Inside the cab it sounds like a lame PowerStroke diesel common-rail injection without the diesel knock.

Mine does it to...so annoying.i took mine to the dealer to have them look at it cause i thought it was manifold crack and all they told me was normal injector noise,if ya ask me they dont want to spend the money on replacing the manifolds.

I have cracked manifolds and they are way louder than the injector ticking. To me, the injector ticking sounds more precise and defined, whereas the exhaust ticking has a "mushier" ticking sound and is particularly obtrusive if you drive with the window open alongside a concrete barrier or through a tunnel.

you guys find anything that helps quite down the ticking of the injectors? any fuel additives?
