1. Check the timing chain tensioner. The timing chain tensioner is responsible for keeping the timing chain tight and preventing it from making noise. If the tensioner is loose or damaged, it can cause the timing chain to slap against the engine block and make noise.
2. Inspect the timing chain guides. The timing chain guides help to keep the timing chain in place and prevent it from jumping off the sprockets. If the guides are worn or damaged, they can allow the timing chain to move around too much and make noise.
3. Replace the timing chain. If the timing chain is stretched or damaged, it will need to be replaced. A stretched timing chain can cause the engine to run rough and misfire, and a damaged timing chain can cause the engine to stall or even break down.
Here are some additional tips for diagnosing and repairing a noisy timing chain in a 1995 Nissan Maxima:
* Use a mechanic's stethoscope to pinpoint the source of the noise.
* Remove the valve cover to inspect the timing chain and tensioner.
* If the timing chain is worn or damaged, you will need to remove the engine's front cover to replace it.
* Be sure to follow the manufacturer's instructions for timing chain replacement.
