Wow that's interesting.. I didn't replace that chain rail when I just had mine apart but it did not show any signs of wear. I did replace the top one between where the cams are. Hopefully that doesn't happen to me or anyone here.

You had a shop tear into it for you, curious as to how much they are charging you if you don't mind.

 

Yeah I had shop do it for me, because I dont have the opportunity to do it myself here in Brooklyn lol.

They are charging me $500 for the labor plus parts. It is a good price, because dealer charges around $1500-$2000.

I would suggest you putting an updated chain rail, but hopefully nothing is going to happen with yours.

 

Sticky this.

 

Yea I would if it was still apart, but its back in the car and running. Hopefully I have had my share of weird rare problem with my engine and wont have another one like this..

I take it you are doing the secondary chains and rails too right?

Nice find tho definitely

 

No. Rest of my parts are in really good condition, so I am not going to touch them. I am only replacing that chain guide. Also, I will add more clips and speacial glue on it, so it will be more reliable. However Nissan already knows about this problem and they redesigned the parts.

The reason mechanics charging us that much money, because it is real pain to get that timing chain cover off.
Btw our timing chains should last the life of the car.

Honestly, I like this motor power vise, but with this faulty valve mechanism we got wned: lol

 

Yeah the chains are good for the life, but the secondary chains have problems and are prone to making noise at higher mileage. You might as well replace the secondary chains and tensioners per that TSB. Would suck to have to pull the timing cover again to replace those tensioners later because now you have the whining noise.. just saying.

I know how much a PITA it is to take off that cover, as I did it myself :banghead:

 

Yeah I wish I could, but it would cost me money to put in. It is a big job because you have to adjust cams and etc.

Fingers crossed nothing would happen again.

 

Nice Post!

 

Btw our timing chains should last the life of the car.

just a FYI most automakers assume this to be "100,000"
just like those "lifetime Transmissions"

to expect a wear part, not just something mild but a HEAVY wear part to last longer then that..... Mine Rattles when cold but besides that.. I only notice it after startup.. I always Have. since the Day I bought my Car...

to the OP, good post great info.

 

Thanks for the info -

I am looking into eventually purchasing a low mileage engine and doing a few upgrades to it. Not that my car needs a new engine now, but VQ35DE's are pretty cheap. I honestly think my engine will carry me well since I average about 300 miles every 2 weeks, which works out to approximately 7800 miles a year.

 

Update:

Picked up the car today. Everything is working perfectly.
Everything is running smooth and quite.

My problem was a broken timing chain guide.
Will post a few more pictures later

Max

 

good sticky. my car has this problem on cold start up. ticks for a few minutes then stops when it's warm. i'm definitely not looking forward to doing this work over the summer.

 

I'm right there with you. I'm going to see what parts are required and post them.

 

heres some of them. It doesnt have the chain rail that breaks in this list below. But while you are in there you might aswell do the secondary chain guides/chains.

The Part numbers for the TSB for the secondary chain noise are below.
Secondary Chains: 13028-ZK01C - QTY 2
Tensioner Shoe(Guide rails): 13097-ZK01C - QTY 2
O-Ring Front Cover: 15066-2Y510 - QTY 2
O-Ring Front Cover: 15066-5E510 - QTY 2
Crankshaft Seal: 13510-7Y000 - QTY 1
Drain plug seal on oil pan if you wish to replace it: 11026-01M02
Oil pan front seal: 11121-7Y000
And the rail that breaks, someone else can fill that info in.

 

Nice, thanks a ton for the list Aaron!

I had my timing chains serviced and I a year later I am having a rattle for a second at cold starts. It makes me wonder if the dealer did the work....

 

I would wonder also , you weren t there to check them out . Some places cut corners .

 

Ordered this a couple days ago:

04 09 Nissan Altima Maxima Quest VQ35DE Timing Chain Kit w O Gears Water Pump | eBay

And a couple O2 sensors.

 

Im planning on going this route as well. Have you installed the kit yet?

 

Becareful Chris ordering such stuff like this off ebay. Last thing you want is to end up with cheaply engineered Chinese junk for such a critical fix/repair. You should call them directly and ask the country of origin on this set...at least it will provide peace of mind....unless it IS Chinese junk engineering crap.....lol

 

I did. I was very leery of what I was buying so I grilled the guy and went through a ton of reviews on their page. And I also figured that since I'm leaving the OEM chains in place (mainly because I'm afraid to be off one tooth), if the shoe breaks, it won't be a terrible repair. And if the engine is destroyed, it gives me an excuse to rebuild/replace it with additional value added fun.

And isn't GMB considered a quality after market brand?

 

I have 110k on my motor, is the timing chain suppose to be changed out, I was under the impression that u didn't have to sense its a chain not a belt, car runs great n its baby driven sense my wife drives it daily

 

I have 110k on my motor, is the timing chain supposed to be changed out? I was under the impression that you didn't have to since it's a chain and not a belt.The car runs great & its baby driven since my wife drives it daily

^Translated to English

And no, you do not have to change the chain.

 

Is there a OEM kit available to purchase all parts at once? My engine is currently torn apart and had the parts from Advance Auto and they were the wrong parts. Every piece was wrong. Took it back and none of the parts they listed was the correct parts. Sooo with that being said I need to order the correct parts and have them overnighted so I can fix the car. Or a parts list?

 

Have a look at Post # 16 mate .

 

Yup, installed just fine. I have a P0011 code (intake sprocket is over-advanced), but I think that's from my own doing, not the kit. The secondary tensioner springs aren't as stiff as the OEM springs. It's an Evergreen kit, water pump is...Dang it I forgot the name...It's a popular brand...Starts with a G. I saw a couple of other kits on ebay for cheaper, but I'm not sure if I would've gotten the same thing.

Make sure you order a gasket kit also. You should replace the lower timing cover crescent moon shaped gasket and your VTC solenoid gaskets. If I were to do it over again, I would have dropped the engine. If I couldn't do that, I would have utilized a shop crane sooner and disconnected the motor mounts. Then at least the motor can be moved around for easier access.

 

just wondering you you shouldnt replace the sprockets while your there. i know from my area of work that a chain driven motor the chain will eventually break. im thinking just replace the chain and dont worry about the sprockets unless they look shot. i dont know can someone verify this?

 

Anyone know if there are timing chain replacement "how to's" anywhere for this specific motor? 08 3.5se In my coupe is getting pretty bad...rattle on start up, and now a lot of the time when I let off the gas, I hear it slapping something. Doesnt sound like either of the 2 videos posted above. Found a video on youtube but it sucked.

 

You a mechanic? From what I see its not the most fun job to do.. Ive done alot of work on cars, and have done a few timing chains, and alot of timing belts... From what Ive seen, its best to just pay the dealer $1500-$2000 to get it done right

 

I think he'd pay more than $2k at the dealer. I was quoted around $2500 here and the labor rates are lower.

 

I was quoted about $2200.00 and this is here in florida........ Here they gouge the chit out of old people...so I did it myself. Wont do it again. lol
