V35 Vq25dd Engine - Timing Belt Or Timing Chain?

Hi guys,

I have heard differing stories about this. Some people on here seem to have mentioned that the V35 (specifically the VQ25DD engine for the 250GT) runs with a timing chain instead of a belt, which hence would not need replacing.

However, I have checked both in my V35 Skyline owner's manual (with maintenence schedule) and also under the bonnet, and in both places it says to replace the timing belt at 100,000km.

Does anyone here know for sure?

maybe they mean engine belts, like what would have been called the fan belts except they are now thermostatically controlled or viscous controlled.

anyway, all VQ engines run a timing chain that probably wont need changing in the life of the engine if its looked after

zei20l is correct.

Timing CHAINS for all VQ's.

Yes, under my bonnet it states timing belt change at 100,000kms... But I assure you, the VQ engine has a timing chain.

Why don't you call Nissan if you are still unsure?

Thanks for this info. I guess I just struggle to understand why they would put that under the bonnet and also in the service guide if it wasn't necessary and they run a chain. That would seem strange.

I've asked Nissan many things regarding the V35/VQ engine, and frankly they have been pretty useless on every occasion so far.

But thanks for clarifying.

Try a different dealership. :banana:

Or just change the vehicle reference to "350z"

Some know what they are talking about and find a imports interesting whereas others (the majority, unfortunately) just go through the motions.

those manuals you get have probably been 'converted' from the R32/32/34 days and they neglected to change the timing belt thing because - well, i dont know why, but whatever the reason its wrong :)

      Can't forget them. Have spent the better part of the last 2 years in Bunbury. Any longer and I would have to get one of each.

      Hit it hard last night, was in the shed till 2:30am. Had to get everything ready to try fit engine today as neighbour is going away tomorrow. This happenned today      Was going smoothly, till it wasn't. Had to lower the sway bar, remove engine mounts to get the engine to its spot and then refit everything. Head drain also created some clearance issues but got there in the end. Some idiot put the drain return on the sump virtually where the engine mount is. Hose fits on but is less than ideal, going to have to revisit it and fit a 90° fitting. Had some hiccups last night too with getting the flywheel and gearbox on. Firstly forgot the sandwich plate, so had to remove clutch and flywheel again. Then gearbox went on smoothly but then realised new block has an alignment dowel in the same spot as gearbox. GB off again to remove said dowel. Cnut. Anyway, it's in now. AC and PS pumps refitted, tail shaft bolted up as well. Left to do is reconnect all harnesses and plugs. Looks like a big mess ATM. Fit dump pipe, radiator, shifter, intake piping and associated bits, air box fill, afluids and hopefully fire it up. Looks like couriers please has lost my break in oil again. Useless pricks. Looks like I'll just get whatever mineral oil is on special at super shit auto. Hopefully it will actually run after all this or I'm going to burn it, lol.

      The genuine ones are a minimum of $95 each on amayama. Jesse Streeter just quoted me $190 each. I can get a set of 6 MSD for $470 on ebay.

      New Monroe OESpectrum shocks for the Honda have been ordered, the car actually handles well with the OEM shocks, but from pulling the wheels off for a good inspection of the brakes and bushings, the only issue I saw was that it still has the original shocks, and with 160k km on them they are well past their use by date Also, in other "kids these days" news, the airbox resonator is "in the bin", a little more induction noise down low free reving, but it sounds really good (growly) over 4k RPM on the road, worth while silly mod for 10 minutes of work and zero dollars Also the K&N filter for the OEM airbox arrived, whilst I didn't get it for performance, as it probably doesn't give any, it's more to save a few bucks replacing OEM filters every service, 3 filter changes and it has paid for itself I also picked up another 5 litres of HPR5 for another oil filter and some more engine flush, I'll give the last HPR5 and filter change 1k km to do it's thing then flush it all out again and stick the new stuff in, anal, but I feel it's always worth the effort when I get a "new old" car to really clean out its guts, and as the K series engines have a few internal mesh filter screens for the V-Tec thingie, as well as the usual one on the oil intake tube, it's preventative maintenance to keep the oily bits happy when I'm wringing it's neck The Bogan Cruise Ship might even come out from undercover this weekend for a cruise, weather permitting of course
