First,check to make sure that you have enough oil in the engine.second,that oil is pumping up to the lifters. and last, if everything is ok, you might want to add some type of oil additive to see if that quiets them

My engine is making clicking noises when I start it. This lasts for about 10 minutes.


Sounds like a lifter hasn't pumped up . Put an additive in the engine oil that quiets noisy lifters. Any auto parts store or even walmart has it.

What does a loud clicking noise indicate that seems to quiet as the engine warms when cold starting a fuel injected dodge pickup indicate


The oil may be to thick or a partially blocked pick up (check the sump for a big dent) Lack of oil changes will also cause it as the oil starts turning to sludge & partially blocking things. As the oil warms it gets thinner allowing it to pass around the motor easier. I DON'T recomend the oil flushes. The motor may have to be partially disasembled eg: sump off to clean pickup or tappet cover off to replace lifters etc... Start by changeing the oil & filter with the recomended grade.

2001 Buick Lesabre lifters noisy


Have you tried flushing the engine crank case? You may have sludge clogging the valve lifter oil pressure ports. Get a can of Berrymans brand Chemtool, add it to a cold engine crankcase oil and run it for 5 miles or so, then change the oil and see if the noise level improves. Some tapping noise on cold start is normal and not a sign of any problem. If the noise goes away in my opinion I'd just do the flush of the system and then leave it alone.

I have a 2004 Toyota Tacoma. During the last 2 months when I start the truck in the morning I hear a "tac, tac, tac, tac ...." noise for 30s to 1 min than it stops when I drive away. This...


This is most likely a noisy lifter (or valve tappet). In cold weather, the clearances in the valve train open up because metal contracts due to the cold. Once the oil pressure comes up after start the noise goes away because the larger clearance fills with oil and the lifter becomes "cushioned" with the oil. The proper fix is to have the valves adjusted. I believe in your model, that is done by putting shims on the lifters. This will quiet the noisy lifters. In the short term, you can try using a lighter weight oil for cold weather. This will get the oil to the lifters faster after start up and quiet the tapping more quickly. Once the weather warms again, shift back to the normal weight.

All lifters started clicking at once


Sounds more likely to be a timing rattle rather then all the lifters at once making noise, if your EGR valve is bad this will happen and if the timing is off it will also do this, I can't buy the theory all 16 hydraulic lifters are noisey unless you over reved it something fierce, or ran it out of oil, or had someone loosen all the rockers.
Happy Motoring!!

I have a 2002 dodge dakota when i start it theres a clickin noise sounds like a lifter or a exhaust leak but it quits when it gets warm


it could be either,you need to trace noise before it warms up,the only exhaust that will make that type of sound would be a exhaust manifold leak,if the noise is the top half of the engine,take a long extension and touch along the valve covers and hold it to your ear,just touching your ear.

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!
