Help Rattling noise from the engine compartment

[Legendary]

Hi ,
I am new to the forum and I am trying to find some answers for my problem.
I recently bought 06 Nissan Murano SL with about 55000 miles.
The problem that i am having as i can see is the same as many other Murano owners.
Basically I am having a rattling noise coming from the engine area. It only happens when you accelerate and with in a range of 1200rpm to 2000rpm after that is gone.When in park or neutral you wont hear anything no noise at all. It only happens under engine load. When i start the vehicle in the morning the engine is a little bit loud and i would say acts lazy. And the rattling noise/sound like an old diesel engine shows up after few minutes of the engine running. I can hear the noise coming from the engine compartment, especially on the passenger side and is very annoying. So after driving for longer time maybe 30 minutes or more I can tell that the noise goes down maybe even goes completely away or its very small that i can't hear it . It could be still there but not like on the beginning.
I have been using high octane fuel and the oil has been changed so I think that's not the problem.
My opinion is probably the fuel damper because the rattle comes from that part of the engine.
Please help any leads what i should try.

Welcome to the forum.

I am going to suggest defective fuel dampers.

I would check your oil level when it rattles because it could be the timing chain you are hearing rattling. If your Murano is losing oil between oil changes that could cause the chain to rattle in the case due to having a small amount of oil in the crankcase. Do your Murano have an oil consumption problem or possible oil leak?

Please post the followup to this. We have owned our 04 since new. Only has 70 k on it. Ours makes the same noise. Its been doing it for the last 2 years. The oil disappears also. About a quart every couple hundred miles. No leaks, no smoke, no burning smell. Quiet as can be in neutral. Even if you gun it. This car has been the most expensive piece up junk i have ever bought. I just put $ 750.00 worth of tires on it yesterday so we 'll have to keep it a while longer. I would love to fix the noise but there are about 6 things on this forum that guys say it is. I have a bad feeling the stealership wouldnt know either but would be more than happy to experiment at my expense.

I had the same problem,no one could find the source untill 6mts ago.It turned out to be the flex pipe on the front tube(exhaust)Do not go through dealer for this $1,300.Aftermarket 2-300 took me 30mins to exchange

I get the rattle noise on acceleration if my oil gets too low. Once I change the oil or add some to the proper level it goes away.
