Nope, they mostly last forever, but some fail. Could be the internal chain tensioner,which I think has some externally serviceable parts.
If it was the chain, the frequency would be very high relative to the RPM's. Perhaps you are hearing sticking lifters or valves. The fact that the noise goes away when the engine warms up seems like a good sign.
If it is sticking lifters or valves, I suggest trying some oil additive that has solvents to free sticking valves and rings. I would also want to be using Mobil 1 10W30. The timing chain is major work, so I would be trying the chemical approach out of desperation in any case! Msybe the timing chain tensioner gets sticky? You might try a can of additive with your current oil, then drain and fill with Mobil 1 then add another can. But if you are using Mobil 1 already, that would be a different story...
Please post thoughts on frequency of noise VS RPM's.
I like your removal of the belt. A very defintative move!!!
