If the noise is emanating from under the valve cover, it isn't the timing chain. It can be a stuck lifter and you might want to try a lifter cleaner from an auto parts store. I think you will need to change the oil after adding the cleaner and running the engine for a while. If the engine uses mechanical lifters, the noise could be coming from a bent rocker arm or a worn push rod.
You may be able to narrow down the source of the noise by using a longer screwdriver, placing the tip at various places and resting the handle on the bone behind your ear. Obviously, stay well clear of anything rotating.

Audi a4 1998 tapping noise only when idles under valve cover


Sounds like a bad valve lifter or a valve out of adjustment. It's probably a bad hydraulic valve lifter. In idle, when the oil pressure is lowest, it is not filling with oil. When the motor revs up, oil pressure rises and fills the faulty lifter.
If you do have mechanical lifters, the valve is probably out of adjustment. If you do car work, pull the valve cover and see if it's adjustable. Of course, you'll need the specs from VW/Audi.
Otherwise, it's probably a shop job.
Sorry.

My 2ltr V6 Vitara has a rattle. Top End noise, it rattles like noisy tappets on start up and gets less as the engine warms up (around five minutes) then it almost stops. So far I have pulled the rocker...


this is not SOLIDS engine, there is no LASH setting, !
the engine has a chain, and a set of hydraulic bucket valve lifters.
the chain can be bad or any lifter, can be dirty and collalpesd.
when the engine is dead and no oil pressure the lifters are normally collapsed, when you start the engine. oil pressure does 2 things
all lifters pump up, and clearance goes to zero. (no noise)
then the cam tensionor, pumps up (they fail) and chain noise ends.
some noise is ok , cold start, but most end after a minute or 2.
started.

ever read the manual? its here.
use a stethoscope to find out 1 thing , which is it the chain or lifters making that noise.
ive even runs engine with the valve covers off (messy , use a blanket to catch oil flying) to find the true cause.......

read the 2.5L here. its close. (mech. parts)
read the Alldata virtual FSM.

Ticking noise from engine on 1997 kia sportage


Sounds like your problem might be bad lifter or bad rocker arm spring. Either way you'll probably have to remove the valve cover to check both. You might also go to a parts place and purchase an oil additive to see if it might help free up the lifter...if thats what it is.

Grinding nose from timing cover and a tick from valve cover could that tick be chain slap or is the 2.4 a no tolarince motor


The Tick is more likely worn lifters and cam. The grinding noise is most likely the timing chain guide is worn out or broken. Possibly a bad timing chain Tensioner. That IS an interference engine.

2001 Sunfire 2.2L, Car started Noise seems to coming from top of Eng . Lifters is my guess, is there anything that would make similar noise, or that I should be checking, How can I be sure it is lifters?


You make have a bad or sticking lifter, remove the valve cover and have someone tap the key, make sure to disconnect the ignition coil to avoid the engine from starting, as they tap the key you will look for the valve to close, a good way is to watch the one next to it open, when the valve is open then you will know the other is closed as there are two valves per cylinder. with the valve closed grab rocker arm and see if theres a lot of play in the direction it moves if it does then look at rocker and push rod and if those are good then you have a bad lifter. if this engine use an overhead cam then there will be no rocker arms or push rods you will need to look for any worn lobes on cam, a stethiscope would be a good tool. start engine with cover off and listen to each cylinder and pin point noise, this will get a little messy as oil will be splashing out a little but its the best way to locate the noise. poor oil flow would cause this also or a loose timing chain. i would start at the top first and look inside cover. good day.

My engine is making noise like a diesel car and someone said is timing chain and tensioner or hydraulic lifters


If the car has done more that 60000 miles then it is time to change the timing belt and also check on the maintenance schedule of the manufacturer.
The noise of the engine always requires a first hand observation so as to determine the exact fault. Possible that an oil change with checking of all timing/valve settings, replacement of timing chain, tensioner, will reduce the noise.

1997 nissan pickup 4wd, just had timing chain replaced , now have noticeable knocking noise coming from valve cover ? mechanic says need new stack shims on valve rockers ?


Not likely. You have a 4 cyl engine with over head cam. It has hydrolic lifters. If it wasn't making the noise before he replaced the chain, then its something he did...or didn't do. If it was making the noise before, most common reason would be 1 or more lifters not pumping up. If you have a six cyl, no one changed the timing chain, (It doesn't have one!) The 3.0 6cyl has a belt.

Ticking noise from engine


You might have a bad hydraulic valve lifter (assuming this engine has them)... you could try an aftermarket product designed to unstick valve lifters.... any auto parts store carries them.
