It might not be the timing chain, check if the exhaust muffler has not come adrift.
By replacing the chain and tensioners.
timing chain making a noise?
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.
Sounds like a loose timing chain.
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.
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
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.

If you hear any noise from the chain it needs replacing.
Pulsar timing chain noise refers to the irregularities in the timing mechanism of a pulsar, often caused by variations in the mechanical components of the timing chain system. This noise can arise from factors like wear and tear, misalignment, or insufficient lubrication, leading to fluctuations in the pulsar's timing accuracy. Such noise can affect the precision of measurements in astrophysical observations, making it crucial for scientists to account for these discrepancies in their data analysis. Understanding and mitigating this noise is essential for improving the reliability of pulsar-based timing systems.
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.
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.
unless there is noise coming from the timing chain, you should never need to replace it.
