Twenty bucks says the retaining nut that holds the EGR tube onto the driver's side manifold has rusted off. Take a flashlight and look carefully. You'll probably see a gap between the nipple on the manifold and the base of the tube where the nut used to be. It's not an easy fix. The correct way is to buy a complete new EGR tube and pray that the threads on the manifold are still good enough for the new tube/nut. We welded the tube to the manifold on mine, and so far so good almost 10 or 12 months later. That clicking drove me insane before I fixed it.

So you're saying a broken EGR tube on the driver's side will cause a ticking sound on the passenger side? Guess again.
