My 60 also makes a very mechanical sounding ticking noise I can only hear from inside the cabin. I tracked it down to a leaking EGR J-pipe. It goes away when I disconnect the EGR valve vacuum line, as well. Exhaust leaks can sound very much like metal on metal.
I should check around the egr delete plate. Mine has the full desmog. I didn't expect a noise from there since there should not be positive pressure inside the intake manifold.
Very well could still be coming from the cat where I have a known leak.
