This sounds like an oil pressure problem. The lifters need oil pressure to work properly (and quietly). Check to see what weight of oil is in the car. Heavier oil will exaggerate the problem. I think your car calls for 5W-30. Also stay away from Pennsylvania oil (i.e. Quaker State), they have a lot of perafin (wax) in them that tends to clog up the engine.

Slight tapping noise from engine when accelerating when engine is warm.Started about 3 days ago but hasnt got any worse.Doesnt do it when cold.


tap usually associated with lifters when vehicle warms up oil thins out and a bad or worn lifter will make a tapping noise --other oil level low --oil needs changing --low level will starve rockers/push rods/and lifters which will also cause tap ---damaged /dirty{sludge oil can cause same problems

Rebuilt engine 3800 and getting a tapping/ticking sound at cold start. Brand new lifters rocker arms are not new.


Here are 3 causes for lifter tick!
Bad Lifter, Dirty Oil Deposits, Bent Push Rod, The rocker arms will make a noise if push rod clearance is not adjusted right. God-Bless! and hope this helps you!or the rocker arms may be worn.

1996 vortec 5.7. how do I adjust rocker arms when the motor is cold?


these are adjusted the same way 5.7 litre motors have been adjusted since GM started making this size of motor. with every thing in place tighten rocker nuts down until about 1/16" threads is protruding above nut. once the car starts allow the engine pressure to build and oil is squirting around rockers. then with engine running tighten down rockers that are noisy until the noise has just gone. then back off nut until it starts to clatter then tighten 3/4 of a turn. repeat to all the other rockers and your done.

Hello, I have a 2001 chevy tracker with a 2.0 engine. It has a ticking noise after it warms up. during up shift at RPM's about 3000 it rattles like lifters, but go away after the shift. Some times


when oil is cold it is thicker and stays [on]coats metal as oil warms up it thins out and flows better[makes it thinner will hear ticking] sounds like a bad lifter or even camshaft lobe problem ,could also have a problem with a loose or out of adjustment rocker arm

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 .

2001 jimmy makes a knocking noise when cold. as it warms up the noise gets quieter then stops. It sounds like the rocker arms are tapping?


Most likely it is the rockers tapping the lifters. the crankcase has only leftover oil in it at the start, and has to wait for the oil pump to get it there.
I would add a stablizer to your oil...like LUCAS. It may help a bit with a cold engine.
If the knocking is in the piston, then you should see some indication on the spark plugs...like oil or blow-by build up.

98 dodge caravan 3 liter ticks on cold start,


SOUNDS LIKE YOU HAVE STICKY LASH ADJUSTER(LIFTER)..MANY MILES ON IT?HAVE YOU BEEN GOOD TO CHANGE OIL AND FILTER?TRY CHANGING THE OIL AND FILTER AND ADDING AN OIL SUPPLEMENT ..IF THIS DOESN'T WORK,YOU WILL HAVE TO ISOLATE WHICH BANK OF ENGINE NOISE IS COMING FROM,REMOVE VALVE COVER AND YOU CAN TO SEE WHICH ONE(S) ARE MAKING NOISE..PUSH DOWN ON EACH ROCKER ARM..A BAD ONE WILL BE SOFT..A GOOD ONE WILL BE HARD..NO LASH..TO REPLACE..YOU REMOVE ROCKER SHAFT BOLTS AND ROCKER SHAFTS..YOU CAN PURCHASE ONLY THE ONE(S) YOU NEED..BE CAREFUL WHEN YOU REMOVE ROCKER SHAFTS..THE LIFTERS CAN FALL OUT..GET A STICKY GREASE TO HOLD THEM IN ROCKER ARMS DURING REASSEMBLY..I HOPE THIS HELPS

1994 mitsubishi mighty max valve tapping noise(occationally) when warm or cold. i took the valve cover off to try to adjust the rocker arms but it is non adjustable, what could it be? Bad oil pump?


How many miles?
Could be a bent pushrod.
Could be just a high mile engine that needs overhauld.
Could be you engine needs higher octane fuel...as engines get older and worn they will benifit from higher octane.

TAPPING IN VALVES


ENGINE CLICKING NOISES
A clicking or tapping noise that gets louder when you rev the engine is probably "tappet" or upper valvetrain noise caused by one of several things: low oil pressure, excessive valve lash, or worn or damaged parts.
First, check the engine dipstick to see if the oil level is low. If low, add oil to bring it back up to the full mark. Is the engine still noisy? Check your oil pressure. A low gauge reading (or oil warning light) would indicate a serious internal engine problem that is preventing normal oil pressure from reaching the upper valvetrain components. The cause might be a worn or damaged oil pump, a clogged oil pump pickup screen or a plugged up oil filter. Using too thick a viscosity of motor oil during cold weather can also slow down the flow of oil to the upper valvetrain, causing noise and wear.
COLLAPSED LIFTER NOISE
Worn, leaky or dirty lifters can also cause valvetrain noise. If oil delivery is restricted to the lifters (plugged oil galley or low oil pressure), the lifters won't "pump up" to take up the normal slack in the valvetrain. A "collapsed" lifter will then allow excessive valve lash and noise.
VALVE LASH NOISE
If you can rule out lubrication-related problems as a cause, the next step would be to remove the valve cover(s) and check valve lash. On older import engines, mechanical lifters require periodic valve lash adjustments (typically every 30,000 miles). Too much space between the tips of the rocker arms and valve stems can make the valvetrain noisy -- and possibly cause accelerated wear of both parts.
To measure (and adjust) valve lash, you need a feeler gauge. The gauge is slid between the tip of the valve stem and rocker arm (or the cam follower or the cam itself on overhead cam engines) when the piston is at top dead center (valve fully closed). Refer to a manual for the specified lash and adjustment procedure. Also, note whether the lash spec is for a hot or cold engine (this makes a big difference!).
On engines with hydraulic lifters, oil pressure pumps up the lifters when the engine is running to maintain zero lash in the valvetrain. This results in quiet operation. So if the rocker arms are clattering, it tells you something is amiss (bad lifter or worn or damaged parts) or the rocker arms need adjusting.

Let me know if you have any other questions.  Thanks for rating my response and for using FixYa!
