It can still mean varnish or dirt. It can mean other things as well.
Easy enough to try. Pick up your favorite additive, use it according
to instructions. (Right now, I would normally lean to Mystery Marvel Oil,
but am openminded about it. )
If it stops the problem, think about improving the quality of oil you
are using, and perhaps change more often if you are one of those
long interval maintenance types.
I agree that todays oils are excellent, however, it's going to take more
than that knowledge to clean the dirt or varnish out of his lifters.
I like Rislone for this particular problem. It isn't so much an 'additive'
as it is a light viscosity, high detergent motor oil, that can be left in
from oil change to oil change.
Some additives are a waste of money, but this is not his potential issue.
If he has used certain oils which tend to gum, and if he has not changed his
regularly, he may have fouled his lifters, etc...
In such a case you don't need lubrication additives, viscosity modifiers,
You need something to help you de varnish the engine and clean it up.
THEN AND THEREAFER, use a good oil, and change regularly.
Shaler Rislone has a long history, as does Mystery Marvel Oil.. There are
as well. They will either help disperse the gum and varnish and cure his
or they wont...
I'm also not a big fan of oil additives, but in this case it's the
easiest thing to try first.
It seems rather unusual to be having noisy lifters in a car that new,
Are you positive that's what you're hearing?

a click-click-click in the morning
when I first start the car.
Gradually goes away as the engine warms up.
A friend suggests it's just oil draining out of the lifters overnite.
His advice; "Ignore it"....
