There are additives for the oil that frees sticking lifters. Try putting some in the oil first. If that doesn't work then you'll have to replace all the lifters . Never just replace just one.

Your lifters have become clogged over the years. Its only after the oil warms up and thins out does it allow oil to "pump up" the lifters. That's why it goes quiet after 5 min. There are several different brands of additives on the market that can fix this problem ,unless you have a more serious mechanical problem, which I doubt.Check your local auto parts store for the additive. Just add it to your oil and "wham!" problem solved. Good Luck!

Does it do it when cold or every time you start it? if it does it every time then I would pull the valve cover off of that side and see if there is a loose rocker nut, if notthen you have a lifter going bad, or has carbon sticking in it.

SOURCE: ticking when cold
It could also be the infamous "Piston Slap" common in 1999-2002's.
GM "standardized" pistons or something like that and they did not fit the cylinders tight enough. The pistons "slap" the cylinder walls and make a tapping sound for the first few minutes until the pistons expand to fit. GM would not fix it and says it does not hurt the longevity of the motor ( yeah ri--ght! ) Do a google search for piston slap.
Oil level would help if it is a lifter ticking but will do nothing if it is the pistons slapping the walls. My 02 silverado has been doing this since almost new and the above description is straight from GM and a few visits to the dealership while under warranty.
