Nissan has an "active" and "on-going" TSB out on this issue. If you still have warranty left you will be covered.
It is indeed your timing chain pre-tensioners and chain guides. The chain guides and worn down to the piston (plastic is gone) and the chain link is rubbing against metal (metal on metal contact) which is causing the whine noise.
Eventually if left untouched the chain could snap and ruin your engine.
Since our cars are FWD the timing chain cover is almost impossible to reach without dropping the engine. Plus I believe you may run into issues with back ordered replacement parts.
That really sucks. I'm at 66k miles, so out of warranty. It looks like it can cost upwards of $2k+ to have fixed. Hopefully I can work out a deal with Nissan NA to cover some of the costs... thanks for the input fellas.
So what's the diagnosis for this? I just had my car in the dealer for a P1402 code for the stuck EGR and they found nothing (this was last wek.) It's been cold as sh!t here and the whine gets louder with the cold so I just didn't think anything of it. If I take it to the dealer are they going to think I am crazy for having them look at this? Also is the TSB available from nissanhelp.com?

Got the PDF downloaded for the engine whine. I definietly have that and it's on the front left side if you are looking at the motor. Same place you who had the noise got it? Its up high right where the cams would be by the gears. BTW, I only have 52K on mine so it should be a freebe. Just hope they aren't asses and tell me it's fine. They said nothing to me about the whine when I took it in there last Tues.
Just to let everyone know, took my car in last week for the "noise" and told them specifically about the TSB and they agreed there was a problem. 3 weeks ago I also took the car in foe the P1402 EGR stuck code but since I had cleared the code with Cipher they did not open that up. However, this week I brought the car in for the timing repair (requires engine to get dropped out) they discovered my B1 cat was falling apart and stuck in my EGR and tube SO they replaced that and all of the EGR stuff at the same time. Nothing like $3,500 worth of parts and labor done all in one day. Even got a rental and the car washed when I picked it up. Friggin amazing dealer service. I was more than happy as it was all warranted (7K left on powertrain) and the guy in front of me at the checkout had to drop 1800 on his van.
