To confirm good , bad or going bad cam and lifters pull your valve covers , wipe the oil off of the tops of the push rods such that you can make a mark with white out on them.
Start the motor and look for the needed rotation of each push rod.
Every time a valve opens and closes the push rod should spin because the lifter spins.
If at any given rpm some of the push rods spin slower then the others or hardly at all, then you have a Lobe and or lifter going bad.
Nothing last forever, and once a certain level of ware takes place the self adjustment of a hydro lifter can no longer compensate, although you might find that the expansion of a warmed up motor might quite things down some.
