People usually replace them during rebuilds, but I've never heard of a chain failing.
The plastic guides normally fail first. Causing a horrible rattle noise. And once your in there you might as well do everything.
What makes this timing chain system different compared to other engines that require changing at specific intervals?
I'm taking a guess to as if that's what's causing the whining noise on my car.
A time chain is definitely better. Not only will it last longer, but if a chain breaks it breaks and that's all that happens; you have to repair it. When a belt breaks you run the risk of causing damage to the surrounding areas of your car.

Originally a belt driven motor was quieter compared to a chain. Chains often last 500k or life of car compared to belts that need replacement at 60-105k. Some timing belts are quick and easy to do I rather prefer belts ( most sohc 4 cylinder) and some I hate with a passion (vw/Audi v6 motors). There is no better, its a trade off. Kinda like going v6 vs v8.
Nothing close to those noises. I can't figure what's causing the noise the car runs perfectly but that noise is bothering me
It is at start up only or always there?
Check your pulleys. Either idler pulleys( I don't think fx35 motors have them) and all the others. They go out from time to time. I had a bad idler pulley in my g35 at 50k. I just deleted it.
^ he just replaced the pulleys and noise is still there
I had a whining noise on my old Chevy impala 2001 and It was the tranny. Remove the belt from the engine and start the car if you still have the whining then its coming from the tranny
I removed the belts n cranked the car it's still making the noise. I doubt it's my tranny or engine. The car runs fine all fluid are clean and up to there level
If you remove the belt and still getting the whining and most likely it should be the tranny because remember by removing the belt you just eliminated everything that sits on the engine
But everything is working fine. Tranny shifts fine and smooth though the noise is a come and go type of thing. It doesn't do it when it starts up about 15 min after the engine got warmed up. It happens mostly at idle it could be happening when driving but I can't hear it. It'll come on and then it'll go away
Just a thought could it be a bent valve or something ? I thin i seen a similar case with a bent valve ....... I dont mean to have u worry mike hope all is well man .....
I would check your oil level. I bet its low and the whining noise can come from low levels. Probably needs a quart or two.
All my oil levels are good engine and tranny wise.
Can you take a video or sound clip?
I posted a video link on my other thread called whinning noise.
