Check/have check valves adjustment...
Nothing to worry unless it's way to loose.

Lasy lifter will do that... do that when the engine is cold...remove valve
cover and push on the rocker (where the pushrod sit)..
Follow those procedure:

Make sure you are at least 1 turn in... i did some test lately...from 0 lash
to 2 turns in...no difference in compression...

Cheers, Ben

My 1990 Carat, with 85,000 miles, has a noisy lifter after sitting for a few
days without being started.  The oil and filter are changed every 3,000
miles and the oil looks very clean at 3,000. It takes about 8-10 minutes
before the lifter quiets down. Is this something I should be concerned about?
