Well, still is there any chance that the chains will develop stress fatique and failed? I would think even chains would need some maintenance, just perhaps a lot longer than 100,000km ?

The other engine I was told had chains on them is the SR20, so anyone with 200SX is there any timing belt/chain replacement in their service schedule?

Yep, correct.

The VQ35 has a timing chain and not a timing belt.

I have a Maxima with the VQ35 and confirmed this. Basically i have heard the chain may need to be re-tensioned (if thats a word) but as a guide, the recommended replacement time for the chain is 200000miles!!!

I was getting ready to fork out for a new belt on the Maxima until my mechanic told me he confirmed it's a chain. Looked into it a fair bit and found it was correct. Checked the workshop manual for the V35 and yep, it's a chain.

Well the G35 members were saying that the chain based doesnt need to be replaced at 100,000 like the belt driven one, they last as long as the life of the engine.

Done a bit search and yes looks like it's all timing chain for VQ engines... looks like Nissan finally realised the painstaking effort required to replace timing belt in their previous V6 platform, the 300ZX's VG30 series... it's a nightmare job

That's good as that means we'll save that $600-800 cost to replace timing belt @ 100,000km, however that also mean any car done 200,000km in Japan can be wound back to a sweet 70,000km without anyone knowing as there's no timing belt change stamped on the engine cover anymore!

But 200,000 miles said - that's a lot of km, 360,000km approximately, the transmission probably have been needing a rebuild or two before the timing chain is due!

If I'm wrong we can both rock up to my mechanics together!!

Nah, pretty sure it should be sweet, as have read exactly the same on G35Driver. I actually spun out at first cause they were saying change at 200000. Then i remembered they use miles.

I'm pretty sure I'll check again when i get to 100000km's cause I'm kind of anal about things like that :-)

Forgot to add, if you see the complexity in removing and refitting a timing chain, you'll see why they've made them last 200000miles.

The process includes

Drain Coolant

Drain oil

Separate Engine harness

Remove Intake manifold collectors

Remove Cooling fan assembly

Remove A/C compressor

Remove Power steering pump

Remove Alternator

And that's just a few. Putting it back together seem twice as complex :-)

So I was told about the chain as well by my mechanic on my Maxima. He also mentioned how difficult it is to change the spark plugs, which is why they're platinum and only scheduled at 100k kms. Not sure if that's entirely true and if it applies to the V35 (being RWD vs FWD).

The plugs on a Maxima are a MASSIVE job.

I bought a set not to long ago, but once i started, decided to stop about 5 mins into it.

Basically the whole top half of the motor virtually has to come apart. It defiantely though is different on the V35, as being FWD the Maxima's engine is in a east/west config, where as the V35 is north/south, and thus much easier.

The prob with the Max is that the induction system run over the top of the motor. it seems the front 3 plugs should be able to be changed without too much fuss, but the rear 3 are a nightmare.

It is fine. I got my plugs changed when My 350GT first pass the compline. My Mechanic said it is not a hard job, he also said the orgional plug is already DENSO platium all around. He can not see it is factory or pervious owner upgrade them. But I change them anyway.

It has being confirmed guys ive check with a couple of suppilers that supplies V35 / G35 Part and they have all told me it is timming chain. So there you go guys if your car is close to 100,000km you wont need to worry about the timming belt ! :(

In terms of maintenance though, (i have a VQ30det) while the engine is already slightly apart, is there something (like a tensioner) that would be a good idea to check / tighten / lube while i have relative ease of accessing?

All i need to remove (as far as i remember) is the cover as all the auxileries are already off the block.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Duncan's V37.......race car?

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.

      My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment.
