Did you ever verify what the oil pressure is at hot idle when the noise starts. Could be the pressure goes low after things warm up and the oil thins. If one or two of the lifters are on the low end of tolerance they would see the low pressure and start acting up. Specs say 40 psi at driving speed but nothing on idle pressure. I suspect lower than 10 could start giving some issues particularly if the bearings are worn or the metering valve into the timing chain compartment is sticking and letting any extra oil dump into there..
