The timing chaing noise is very common on almost all v6 nissan engines. There is a significant difference for the maxima's though.
Timing chain noise is very common and it is the result of the secondary timing chain tensioners. They often stick and put too much tension on the chain and the plastic guides for the tensioner wear down to metal and that is the noise you hear.
At Nissan, I have performed this replacement many times and I suggest you take it to the dealership to have it fixed.
I would say that it is your timing chain tensioner it may need changed. if you were not the first owner of the vehicle the engine could have been abused and over revved several times causing the chain to wear prematurely.

the timing chain noise on nissan altima 2005 only 80,000 miles and yes this car do not uses a belt and the noise it is only when it is cold o in the firts 15 minutos after started posted again by [email protected]
Obviously it's time to replace the chain...however, I think this car uses a belt instead. Can you pinpoint the source of the noise? There is also a hydraulic belt tenisioner that should keep the belt tight. How many miles on the car?
When you receive advice from this website you have to understand that without the item in front of us, we are only able to provide "a best guess" as to what the problem might be based on you description of the defect. If you haven't described a clear and precise description of the defect you decrease the chances of an accurate reply. Thank you.
to landsend; There is not such thing as a hydraulic 'belt' tensioner, AFAIK. While hydralic tensioners have seals, they also have bleed holes in my experience, and drip the excess oil. They run in the crankcase side of an engine. Belts run in a dry cover, outside a camshaft cover. YOu could not have a tensioner dripping oil in the dry belt cover. you would pump out oil (loss) and oil the belt. Mr K L
