I have been complaining to the dealership about a whining noise from the left(drivers) bank for about 5k now. The first time I brought the truck in I was getting the fuel sender replaced and decided to bring up the issue to see if they had a quick fix. I told them that above 35mph and on acceleration it sounded like I had a supercharger under the hood(one day this will be true). The tech drove it and checked under the hood and instantly said "oh, he has a volant intake. There is your noise problem." Now, I have had the intake on since about 15k into the truck and Im now at 90K. I know the difference between an intake and whining from the motor (Plus I was a master tech for a highline dealership), I even diagnosed it before I took it in. Of course they told me that they wouldn't do anything because of the intake. On Friday I decided to removed the intake and take it back to the dealer because the noise was getting worse. Finally I got them to really look at the truck and they said I was going to be getting new timing chain tensioners and guides under extended warranty. Wow, ya think!
I guess if I had the timing tools I would have just done it myself. We'll see how good the dealership does it because this is the first major repair on the truck.

Mine was done so well and clean that there is no telltale sign that the engine was pulled apart.

i've got the same problem it seems... how long did it take them to do the repair?

My truck is still in the shop but seems like a day or two from what I have heard.

It was there for two days as they did the fuel sender and some other small warranty issues. The chain I believe takes about 7-8 hours.
I was a bit skeptical but the tech did a great job and in a month it will be a year since it was done and still quiet, no leaks and I'm happy.

they will cover your timing chain tensioner at 90k? they wont do mine at 65k and i work(ed) there. Whats it covered under?

extended coverage?

I dropped mine off today

for them to diagnose the whine. I was informed that if it turns out to be something other than the timing chain tensioner and it is not covered under warranty and i refuse repair then it is a 95$ charge for looking at it. What a ripoff that is. I could understand 40$ or so to cover their time but 100 bucks?? Pretty slick trick i would say.

I'll keep my fingers crossed that it is in fact the tensioners. Otherwise there goes $100.

 

[savagehenry]

well, that was quick.

The service tech called back about an hour after dropping it off and said the noise was due to the timing chain guides needing to be replaced. I've read a lot of the post on the forum about tensioners, guides, etc... and would like some clarification. Are there instances where the tensioner is fine but the guide is bad or is it typically both.

I want to make sure they are cutting corners and only replacing the cheapest parts to stop the whine. The tech only mentioned the guides were going to be replaced. is that okay being that the handy NTB posted here http://www.clubfrontier.org/forums/f23/vq-engine-secondary-timing-chain-noise-revised-tsbs-52945/ states that both chains and tensioner "shoes" should be replaced? Thanks

Timing Chains

I have the Nissan Security Plus 100k extended warranty. They have only hit me up for the 50 ded. and thats about it. Im curious to see what they are replacing, so once I go over the repair order I will add it to the forum.

So I got the truck back and everything seems pretty good. I have not had the chance to lift the hood and do a thorough inspection of the work. According to the RO the timing chain wore down to the guide sleeve. Now this might be partially true, but first it didnt seem that bad and the tech may be covering his *** for warranty. Anyways, the noise is definetely gone and they replaced a idler pulley with the timing chain, tensioner and guides. Total cost to me: $50.00, thanks to Security Plus warranty.

Also to Note: I put some LT245/75R16 Wrangler MT/Rs (for a little while before I get some new Nittos) on the truck and man do they rumble. Im interested in seeing how they perform in the desert, but this weekend Im going to the snow.
