MOTOR NOISE BETWEEN 2000- 2500 RPM

2007 Nissan Maxima • 74,000 miles

My 2007 Nissan maxima makes a very odd hissing/ grinding noise when it gets above 2000 rpm and stops when it gets above 2500 rpm. The noise seems to be coming from the motor and I can only hear the noise when I have my windows down. I took it to the Nissan dealership and they said it was my timing chain going bad. I thought it was a little sketchy though because they wanted to charge me $1500 to do the job. I got a second opinion from a local mechanic who said the timing chain looked fine. Any ideas what the cause of the noise could be?

Could be the tensioner hard for us to diagnose noises on here
