I don't think I've ever had lifters that were noisy on cold start that
quieted as it armed up that weren't helped or completely cured by Mike's
filter idea plus a good stiff detergent treatment.  I almost always start
with a quart of ATF in the crankcase (drain/siphon some oil out first)
about 100 miles or so before an oil change. Drive it for that 100 miles, 
change oil and filter and drive until the next oil change is due.  Repeat
as necessary, but unless it's really gummed up one shot is usually enough
although my current one took about three rounds to finally quiet down.  It
had 110k on the clock then and at 185k it's still quiet.
