03/04 VS 05/06 Problems

I’ve read a lot on various forums about the 03/04 models having transmission failure and 05/06 6MT’s have excessive oil consumption.

If possible I want to go with the earlier models to save my money but I was wondering how common the transmission problems are and whether buying a facelifted model is actually justified seeing as it’s not without its faults

I've read that the early 6mt's have gearbox issues, but i'm yet to meet anyone that's actually had a problem. 

I've known of a few guys with turbo or supercharger setups still running the stock clutch and flywheel without issue. 

Overall though, they're pretty reliable cars. The only things I've had to do with my 03 model in the last 4 years is replace the bushes and valve covers.

The 05, 06 versions are a lot less common which may have something to do with the oil burning issue. All the guys in the states complain about it non-stop. The interior is a bit nicer though.

I have a 2004 v35 sedan with 6mt, 160km odo, I'd say it hasn't been treated well in the past.

My vq35de consumes oil, so each week I check the dipstick, probably a 1-1.5mm every two weeks.

The transmission is rough, vibrating, noisy, hates the cold, not half as good as my 98 r34 gtt 5 speed manual.

Wear and tear items like the front suspension arm bushes, rear diff bush, clutch, engine hoses, cam sensors, radiator, rear wheel bearings needing replacement.

+'s the handling is superior to the r34 and I can see out the windows unlike a coupe and modern cars :)

early 6MT had some issues with weak synchros, the 05+ have the upgraded CD009 transmission with triple cone synchros on 2nd, 3rd and 4th which fixed the issues.  has nothing to do with power handling ability.

the V35 Skyline never got the revup version of the VQ35DE like the US G35 and the 350Z did, so oil consumptions shouldn't be an issue on the V35.  My 05 6MT with 150,000km doesn't need any top-ups between services, it might drop a couple of mm on the dipstick at the most.

I believe they also may have improved windows motors too as they don't seem to have that issue either.

      Mistakes were made, my R34 Story

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

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

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
