My 2008 Nissan Titan has almost 148k miles on it. I have read online that these trucks are known for developing exhaust manifold leaks.
The very slight ticking sound is right after first start up and last maybe 5 seconds/8 seconds tops. It has been doing this for the past 3 yrs I have owned it.
I am wondering if this is a manifold leak or something else?
Below you will read a statement that I just read online regarding this topic.

A leaking exhaust manifold will almost always create a ticking or tapping noise. Often, the sound is more pronounced upon startup when the engine and the manifold are both cold. The noise may diminish or disappear once the engine warms up and the manifold expands, closing off the leak.
