Never heard of a grinding timing chain. Maybe your starter is dragging. Get your starter rebuilt. Check your battery voltage and alternator amp output. Check all connections at battery starter and solenoid.
Plug your car in when its cold!

That problem does exist in older Nissan Pick-Ups. Some Used Car books mention this as an annoying but otherwise not troublesome rattle of a chain that has been manufactured too large for years. So the grinding noise can only be fixed with a revised model of timing chains for a lot of $$. Apparently, the noise stems from the movement of the chain itself and not its banging against any housing. After all, it sits in oil, so I just replace the oil more frequently.
Stop driving it because if the chain goes you will ruin the engine. Get it fixed.
timing chain making a noise?
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.

It might not be the timing chain, check if the exhaust muffler has not come adrift.
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.
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.
