First of all - is the oil pressure gauge flickering at warm idle (stoplights)?
Mine has that ticking because of low idle oil pressure, but it goes away with increasing rpm's. And Shell Rotella 5W40 took care of pressure.

It might be also a spark plug (booth) striking outside, to the block. Check at night time in a dark area to see if there are any lights/sparks under the hood. That is more likely because will not go away with increasing rpm's, it will just get "faster".

can you tell where the tick is coming from?
it's possible it's caused by a crack in the EGR valve.

My truck has had the ticket caused by a crack in the EGR valve since I bought the thing 7-8 years ago.
