Hm, yeah that's probably inherent to these VQ Nissan engines...

Have read that the bottom end on these VQ engine is like 'glass' - they're a lot weaker than the RB inline 6.

If you want more bullet proof engine then stick with the RB of R33/R34, but they're getting old as well so all engines when they're getting old they are more prone to failure if being pushed.

Hmmm, bad assumption I think. Cars came from the same factory. What happens in USDM could happen to JDM cars.

Although a complete service history in Japan (if you can read them) may minimise those risk.

As quoted from Forest Gump and a forum member on this forum, Imports is like a box of chocolates, you never know what you're gonna get... can be something you like, or can be something you dislike.

So the problem seems to exist on local 350Z, and since the JDM V35 skyline has the same VQ35DE engine, I believe they should have the same potential problem, it's basically the luck of the draw when buying an import.

Lucky for that guy he won in court with his 350Z engine replacement, however for a V35 import not sold locally through Nissan, the owners of V35 Skyline would stand no chance in court - Nissan's lawyer is just gonna screw us badly for buying something not offered locally. They'll find hundreds of reasons and excuse not to cover it. So anyone who can't live with the risk buying a lemon should stay away from imports.

Any manufacturer's recall on any V35 skyline range will also not be covered by local Nissan dealers either, so we import owners are really left in the dark. If something happens to my V35, then I'll be forking out cash out of my own pocket to get it fix. I was lucky not to had any with my old R33 over 4 yrs of ownership.

Jarthel, My family members has owned lots of Toyotas since the 80s (we have a '07 RAV4 now) and none of them have had any problems with the engines - they're probably the best car to buy for people who want to play it real safe... :( If local Toyota doesn't appeal you, may I suggest to you an import Toyota Supra, Chaser JZX100, or Caldina wagon? I strongly believe they will be far more reliable than V35 Skyline.

I think if everyone change oil every 6 months or every 5000km the amount oil lost due to getting burnt won't be noticeable enough.

The problem is these days modern cars' service intervals are getting longer. Our Toyota RAV4 is every 10,000km service interval including oil change, and some cars I know has a 15,000 km service intervals. Some cars are used harder than the others and whenever the oil hasn't been changed in 15,000km, with a bad or incorrect oil in the engine, the amount burnt off could be seen as quite significant... It's a point to consider..

Still, every engine will burn oil, but at least car engines are not the old 2 stroke lawnmower engines which burns oil constantly, thank god for 4 stroke engine invention the oil burnt is a lot lesser than the older technology... My brother bought a brand new RX8 and the dealer gave him a can of engine oil and asked him to check his oil and top it up once in a while if the oil goes low. Rotary engines BURNS OIL since brand new. It's a known fact, and all rotary owners knows it... I think compared to rotary engines, the oil burnt by VQ engines on average should not be any more worse, unless you had a bad luck and bought a car with troubled engine.

would topping up the oil regularly avoid the problem? if yes, would there be long term effects with this? thank you

No. That's a band aid short term solution.

I had a Mitsubishi Galant which constantly gone low on oil, up to a point where I need to top up the oil EVERY WEEK.

Brought it back to Mitsubishi which investigate and found that the big end bearing seal is worn and the car is loosing oil because of that.

Long term solution you should aim to get the car to Nissan and ask them to fix it as they would fix a 350Z engine. at least with V35 the engines is something that Nissan mechanic has seen before in a local 350Z.

      Squeaking clutch/throw out bearing

      By jayden_l33 · Posted

      I am getting the same issue. Did you resolve it? I just got it after installing my new super coppermix and literally the same issue, new fork, new 18mm carrier, release bearing that came with the kit and replicated the exact same sound.

      Mistakes were made, my R34 Story

      If you like - I have the STL files so I can email em. There's a couple of gotchas (i.e the holes are not threaded so you might need/will need) to utilize some M3 melt-in threads for some of the points. However if you want to be super accurate, and are willing to remove your calipers and your SHOCKS it's a really good tool. You also might need to scale the part that measures the tyre width a bit wider. It defaults to a 7.5in tyre and I mean who is running that. Luckily with the magic of CAD this is very easy to rescale.

      jeebus. glad you weren't under it while performing the stunt. Also thanks for the link to the wheel measurer, exactly what I needed

      Who has a Infiniti Q60, Q50 (V37)?

      By Duncan · Posted

      In the older stuff there were very significant differences 2wd to 4wd, for example Stagea had strut front end for 2wd and double wishbone for 4wd so it was not minor to swap. From poking around the 2wd v37, it *looks* like it might be more possible; some of the parts specifically have "2wd" stamped on them which suggests the platforms are more similar. You'd still want to start with a 4wd half cut to swap stuff from though. I'd suggest if you don't have a tune on the ECU you don't really need one on the trans either. Throttle mapping is in the ECU side (and you can always use a Roar Pedal if you want the throttle to actually respond to your foot), and really if you are happy with the stock power you probably accept the stock trans behaviour too....its all made to be "sporty" not racey.

      So, updates. I have not washed the car since it came back from Tassie. I've driven it around a bit but not got around to actually sorting it out. I DID raise it because I cracked the rear bar leaving a hotel which was very distressing. Interestingly, the car drives more compliant now that it's raised a fair bit (5mm front, 15mm rear). Also noticed that my FR height was 10mm lower than FL. So that's now sorted out, too. I also bought this and had it printed: https://www.etsy.com/au/listing/1576422240/wheel-and-tire-fitment-tool-universal?ref=shop_home_feat_1&dd=1&logging_key=08f604d9fa4cc383550ba985e6ac85cd5cac7fbb%3A1576422240 Now, if I was smart I would have taken my brake calipers off to actually use this correctly but it was evident enough to me that in the region where the caliper was... there was nothing to hit suspension/guard/arm wise. So I'm going with "it'll be fine" after using the tool to hopefully very precisely measure the wheel clearance. Also while doing this, I had the very VERY bad idea of jacking one of the wheels/suspension arms up while the rest of the car was on jack stands. I did this to see how the arm would travel. This all was well and good until the car slid off the stands and went through a fence. So don't do that. Incredibly nobody was hurt and there was only minor damage to the rear bumper as the car didn't have far to slide, and had 3-4 wheels on it. The only damage turned out to be the fence itself which was easy to fix, and a little bit of damage to the fibreglass rear bumper trim. I had already planned to try a touch up paint kit to fix the time I drove into my garage door to see if it'd help in the interim before I get it fixed properly. I used the Dr Colorchip kit after looking online and seeing everyone talking about it. Yes it's made for chips and not huge broken missing pieces and I'll be 500% recommending it for stone chips after using it for stupid things like me. This took about ... 10 minutes and looking at the half assed photo the 30 second job I did on the bumper corner was almost perfect just by using the tiny little brush and painting it in. The sealact stuff to remove over-painting is really useful, so if/when I do it again I'll likely slather the touch up paint well over it and then clean it up with the cleaning solution. The wheels should arrive in a couple of weeks. I am still kinda confident after doing a stupid amount of measuring (and borrowing a set of 18x10.5+15) that they will not fit because I overlooked something, somehow and flew too close to the sun. ALSO R34 GTR guard liners do not fit on a GTT. I bought the undertray brake duct guides and had the wonderful problem of them not fitting my intake, my oil cooler and the liners themselves were even worse. Attempting to fit them won't work in general - You would have to cut them up as another poster mentioned as the bodywork is different on the GTT. At least I can try to resell them. So instead of cutting those up, I cut up my old already-cut-up GTT liners and extended them by using some PP plastic and drilling some 8mm holes for some nissan clips for the 'extra' bit. Because I was happy to cut them I was able to mount them pretty damn forward so I now have some semblance of guard liners, and the brake vents seal the bumper from the bottom. It sort-of-looks like this, to give some idea - If you look at the GTR and then the GTT this is when I realised that I needed to seriously measure as the inside of the rim area is entirely, entirely, entirely different and could not take any internet measurements for granted.
