There are three possible reasons why your timing chain is making the rattling noise.
1. Oil pressure is low: The tensioners that keep the timing chain tight are operated by oil pressure so if your oil pressure is low then the tensioner will not be working properly hence your chain will flap around and hit the guides.
2. Tensioner is stuck: If you have alot of oil gunk on your tensioner then the tensioner will be stuck and not extend out all the way to keep the timing chain tight.
3. Tensioner is broken: If your tensioner is mechanically broken then you need to replace it.
Having said that, before you follow this write-up it is a good idea to check your oil pressure. Also, in this write up I will not go over how to replace the tensioner but rather tell you how to clean it while it's still installed.

you will need new upper timing chain and sprockets. Common problem on altima your year. Nissan has TSB for it. First they had us remove the upper timing chain guide, but after that, they had us replace all top chain components.

SOURCE: I have a 2004 Nissan Xtrail. I have been losing coolant, even though there are no apparent leaks. Now I am experiencing loss of power intermittently, especially uphill, even to te point pf crawling..
Generally speaking, if you are loosing coolant and there are no external leaks, its usually being burned in the cylinders and going out the exhaust.
You can burn a gallon a week and not see any smoke.
You may want to pull the spark plugs and look for signs of a head gasket or intake gasket leak.
Coolant can also weaken the spark plugs and affect the performance of the engine.
