Ticking noises have been reported before that we're coming from the intake manifold. I believe the problem was caused by the VVT actuator and something about the butterfly valves inside the intake manifold.

Hopefully someone who has had this problem can provide you with more information about it. You can also search it, there should be lots of info about it.
