Of course you can always diagnose the most likely one bad lifter and
replace it. A lifter and collapsible push rod tube is that big a deal to
replace.
The only way that oil level can affect a noisy lifter is if the level is
high enough that when parked, the lifter is submerged. If the lifters are
submerged, than the oil is also covering the cam. Lots of pump and foaming
action here.
The 1.9 is not as sensitive to oil level as the 2.1 but it still can make
a difference. The excess oil level is evident if you are topping it off
and this is also detrimental to the catalytic converter.

Mike, somehow I never saw that but even if it exists and I am not aware of
it I am willing to top it up and trade it off for the benefit of avoiding
the weekly annoying lifter issue. I simply feel the lifter problem can
cause
more damage to my old engine than whatever can hurt it by topping it up
to the max point.
I think you have a set of very healthy (young) lifters in your engine.
When they get old and you hear the noise once every week or more you will
want a remedy to cure it. You will want it badly. You will probably not
care
if topping oil up will do anything otherwise to your engine.
Yes, it is a remedy for old and tired engine, not a suggestion for
everyone.
