Ticking sounds from engine compartment

Looking for some help.

2004 V8 with around 125k miles

A couple thousand miles ago it started making a fairly loud ticking sound (maybe 2 "ticks" per second at idle). It does speed up as the RPM's go up and doesn't seem to go away at an level RPM. It does randomly go away sometimes; doesn't seem to be correlated with anything, though. It's loud enough people ask if it's a diesel.

The dealer looked at it, felt/listened around; they didn't have any ideas and told me it'd be a minimum of $400 to go in and try to find it.

Wondering if anyone has had this happen or have any ideas on what the culprit may be. It sounds like valve "ticking" my old Hondas used to get...

Thanks!!

-Jake

I should also note that performance doesn't seem to be affected. Still getting relatively normal fuel mileage. Pick up seems decent. Thanks!

Or the exhaust manifolds.

Thanks! Would that cause a sound from the engine compartment? Are you thinking something in the exhaust manifold?
