Change the oil and filter. Add some RISLONE to the oil. It has been around as long a hyd lifters. It should clean the sludge/varnish from the lifter and the noise will go away.

SOURCE: Lifter ticking when I start my 1999 Chevy Tahoe

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!

There is a possibility that the A/C compressor clutch burned up or got disconnected. Try investigating the wiring for the clutch.

Engine ticking on cold startup


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.

Iratic tick over when warm


Could be many things. Sometimes Exhaust flange joints will get a gap in them and tick. You could be hearing the Injectors, or hydraulic lifters.

The exhaust tick and lifter tick both are temperature sensitive as opposed to the injectors.

What you could do is run the engine and drain the oil and put in fresh cold oil. The first few seconds the cold oil will be thicker and if it is a lifter problem, the oil will cushion the noise temporarily until it warms. The exhaust will already be hot, so you will notice a noise on startup. If the noise generates later, its an oil related problem.

The exhaust flange problem can sometimes be heard when backing up and reversing direction. The Torque puts a strain on the pipe joint as the Torque changes from Reverse to Forward.

I hope my Solution is helpful.

Knocks after you start for a couple mins then stops


Its hard to say for sure .But the most likely thing would be a lifter sticking .It rides on the cam shaft and the push rod sits on top of it and in turn pushse the rocker arm up and thatopens the valve. The lifter is filled with oil but also has a spring inside of it .If the spring hangs up when the engine is cold you will hear a knocking noise until the engine warms up and things expand. It may go away on its owen but make sure you change the oil regulary dirty oil cause this

Will intake gasket leak make the lifters tic when first starting


I dont think and intake gasket will cause lifter noise. It may cause a rough idle and or a miss at idle on cold start up . as the engine warms up the miss or rough idle will decrease . As for the lifter noise this could be cause by the lifter bleeding down or poor oil presure . On your model of engine there is no adjustment on the rocker arms for lifter noise . They are a 0 lash type .

As far as I know all hydraulic lifters can go bad, collapes or stick. And yours are definately hydraulic lifters, rollered yes, which will make them more durable, but they can go bad. The machine shop should have down a leak-down test on the lifters. That is the only way to determine if the lifters are good. I would check that you have proper oil pressure, I'm sure you do. I bought a "rebuilt head" for a Saturn DOHC engine, and the machine shop never did a leak down test on the lifters, and I had the samething happening.
