Ticking sound ...
#44
Hello;
Hydraulic lifters have to "pump up" with oil or there will be clatter. The advantage to hydraulic lifters is no regular adjustment is needed when all works properly. They are really pretty straight forward in operation. Typically, a hydraulic lifter won't lose oil when sitting for a brief period.
I come from the days of solid lifters (still used in high performance engines) and know well what lifter noise sounds like. Also, a collapsed lifter usually stays collapsed. I read:
Ecotech Engines
Most often the noise is heard at all engine temperatures. These engines use an oil feed restrictor to the cylinder head oiling system and a restriction to that orifice may limit the amount of oil to the sixteen hydraulic lifters.
Not precisely to the point, but sort of. The clicking I hear is pretty faint and takes about five miles of easy driving to cease. Doesn't sound like lifters to me. But then, I don't know what it is.
I appreciate your suggestion and will take it under advisement. Maybe try an oil additive although I don't have much faith in additives.. I really don't want to change lifters if I don't have to.
If I ever find the cause I will be sure to notify. In the meantime, I'll turn on the radio... Or just sing along to the clicking.

If it’s faint and about 4-5 clicks per second, then changes to about 1/sec, it’s the high-pressure fuel pump. Much louder if the dense black foam-rubber sound-deadening cap is gone.
But that’s only for 2.0 turbo. Don’t even remember what motor you have but this comment is in case someone with an LNF reads the thread.
