It might not be the timing chain, check if the exhaust muffler has not come adrift.
timing chain making a noise?
By replacing the chain and tensioners.
Sounds like a loose timing chain.
If you have a 4.0 SOHC engine you are hearing the timing chain rattle against the timing chain guides. Some slight noise is normal, but an excessive amount may mean you have timing chain guide and/or tensioner problems. If you have a 4.0 OHV engine, then you are probably hearing some lifter noise. Again, some may be normal, but excessive may be an indication of lifter troubles.
For longer life with less maintenance, the Sentra engine uses a timing chain instead of a cheaper, but quieter, timing belt. You don't notice the extra noise generated by the timing chain.

chain. if you hear a clattering noise the timing chain and timing chain tensioner need to be replaced they are usually sold as a kit
If you hear any noise from the chain it needs replacing.
Piston slap and timing chain related noises can be very similar. If it is a piston slap noise the noise may be louder during power braking and may quiet down as the engine warms up.
AnswerI think this engine uses a timing chain, but I am not 100% positive. Regardless, the noise you are hearing is either a timing chain that is loose or a belt. I would suspect that the timing chain is loose. Have this looked at ASAP.It could also be the timing tensioner also.
It has a timing chain. The majority of 4 cylinders have a timing chain. You don't need to replace it unless it is making noise or the timing is significantly off.
Timing chain noise is most commonly coming from a loose chain. The tensioner could be loose or broken or the chain could be stretched. If the chain slips or breaks before you fix it, then not only will the engine stop running but you could cause serious damage.
unless there is noise coming from the timing chain, you should never need to replace it.
The Ford Taurus does not have a timing belt, it has a timing chain. The timing chain is designed to last the life of the engine, and does not need routine replacement.
no it has a timing chain,supposedly to cut down on valvetrain noise.
A timing chain normally will last as long as the engine. Signs of a failing timing chain are chain noise and or engine that continues to jump time.
Unless a timing chain is making a noise or has jumped a tooth, they need not be replaced. Timing belts need changing according to the specs spelled out in the owner's manual.
does it make noise? check http://forums.nicoclub.com/
Answer to timing belt for 1996 AltimaThey don't have timing belts. At least mine doesn't. Double check your manual or call a Nissan dealer & ask to be sure. There is not a timing belt on this model or any year before or after this model. You have a 2.4L engine with a timing chain and there is no reason to replace the timing chain unless it is making noise. The chain is at least rated at a 7-10 hour job and should not be considered for repair due to the damage that can arise if not careful.
it has a chain and when it needs replacing it will rattle and make alot of noise it souns likes the liftes but its the chain
Normally, not until an overhaul. But if you hear the chain making noise or the timing changes due to the chain jumping a tooth, then replace it, and all gears.
Why are you wanting to change the timing chain? You do not need to change it unless it has broken or is making noise. There is no scheduled maintenance on a timing chain as there is on a timing belt.
The timing chain only needs to be replaced if it becomes loose (You would hear a clicking noise under the hood when the engine is running) have that noise inspected right away if you hear it and it may need a timing chain. But not for a very very long time. Around 150,000-200,000 miles most likely.
our 2000 4.0 explorer xlt had a recall for the tentioner but the noise is still there so i believe there that's not the problem.
Stop driving it because if the chain goes you will ruin the engine. Get it fixed.
timing chains are replaced only if they make noise........however in the case of small engines they should outlast the engine! so you do not replace the timing chaing........seen cars with 200k+ with no issues from the timing chain!
