SOURCE: clattering noise

Be sure to check the front struts and mounts. Open the hood and try to bounce the front-end up and down as much as possible while looking at the strut mounts.

If it is coming from the top of the motor, I would say it is a lifter making the noise. If the sound is coming from the lower end of the motor I would say you have a rod knocking. If it is alifter you can replace just that lifter, if it is the rod I would consider a rebuild.

Is it valve clatter or spark knock. You should not have any valve noise or knocking noises from the engine. Has the service engine light ever come on.

SOURCE: pontiac sunfire valve noise

If it's a ticking noise that speeds up with the speed of the engine, it's a worn valve lifter.
You can try tightening it down by taking the valve cover off and tightening the bolt on the rocker arm, but don't tighten it too much, you will end up with other problems.

SOURCE: is valve adjustments needed on 2000 camry V6

The valve adjustment usually isnt done unless there is valve noise. If you think its valve noise, have the dealer check it or a shop that does a LOT of Toyota work. Special tools and shims are needed to adjust the valves. Its a LOT of work and will not be cheap. You will want to replace the spark plugs at the same time.

How to adjust valves on chevy tahoe99 v8 4wheel drive 5.7

Adjustiyour hydraulic lifters with the engine running Startt the engine and allow it to warm up. Begin to loosen one of the rocker arm adjusting nuts. You should hear the valvetrain just start to "clatter". Slowing tighten it down until the "clatter" just stops and then turn it 1/4 - 1/2 turn additional to set the plunger depth (lifter preload). Continue this procedure on all the valves. If you hear excessive noises or the vehicle runs crappy you will be doing the procedure again. As stated above, if you have access to a mechanic's stethoscope, you can set the end at the top of the rocker stud to listen to the noise a loose adjustment makes, which will make finding "zero" lash easier. I have an old set of valve covers with the top cut out to minimize the mess.

Is it necessary to replace valve lifter or can you adjust lash to reduce clatter on dakota v-8

hydraulics lifters you must replace as they will wear out.

solid tappet lifters can just be adjusted for. Unless you have some custom old engine in yours I'd imagine yours is the first.

You might also try running some pennzoil or quaker state oil to reduce clatter. They're wax based and will often do wonders for semi-clogging the right areas while keeping the other places open. Great for hi mileage motors.

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.
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.
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!

1995 isuzu Rodeo engine noise

valve guides worn and tappet adjustment required, can check tappet adjustment first to see slightly better before removing heads and getting valve guides repaired/replaced on heads common problem
if raise revs to 1500-2000rpm and hold does clatter come and go come and go (valve guides) if there all the time tappet clearance issue
if there only under load (1st rev up) for a couple of times then stops possible big end bearing
all these are common for this engine
