timing chain making a noise?
By replacing the chain and tensioners.
Sounds like a loose 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.
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 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.
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.
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.
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.
no it has a timing chain,supposedly to cut down on valvetrain noise.
