go to nissan to get new studs, theyre not much few bucks.

the stud is not in your rotor, it is in your hub. just hit it with a hammer with the rotor and caliper off and it will fall out the back. dont be scared if you need to hit it hard.

get a new stud, feed it through from behind and then get a washer and a nut and tigheten the nut to pull it all the way through.

for this you either need hold the hub still, like with someone holding the other studs with a big screw driver and tighetening the nut, or put everything back on and get someone to hold the brakes or use a rattle gun

Since one has snapped i'd consider replacing all of them if it were me. Some dumbass has probably overtightened them and they're all suspect. I couldnt believe how much over-tightened stuff i found on my car.... At the very least hold the new stud up against the other old ones to see if the threads "intermesh" perfectly. If they dont it will mean that the stud is stretched and about to fail.

FWIW its very important torque you wheel nuts correctly, you can get rotor warpage if you dont. IIRC its 100-110Nm. Also remember to use the "pentagram" order when you tighten them up.

HTH,

Thanks for the replies guys, I thought for a second I was going to have to replace the whole thing :D

This may be an stupid question but hey, how do you apply an specific amount of torque to a nut? I mean is there an special torque measurement device thingy :D

Thanks again guys

Yep the thingy is a torque wrench. I got a half inch drive Kinchrome (which is a good brand) for $70 at Bunnings, no doubt you could get one cheaper if you shopped around - just get a good brand. Your car will love you for treating her nice.... Next thing you need is one of those .pdf's of the workshop manuals so you can lookup the torque setting of whatever you're doing up.

soon people will need torque screwdrivers, seriously its not hard to know when its tight enough lols

this is a lil bit wrong, with a good example being the exhaust studs on the manifold.

If u do it with a torque wrench u will fin it takes bugger all to get to the required specs. If u do it by hand u will over-tighten the nuts guaranteed. Which is why all RBs end up with snapped studs on the exhaust manifold....

RB25s and RB30s not RB26s, they break because they have a long manifold that warps not because they are overtighten.

Don't forget using a swivel ( uni) is not going to be the same tention as the nut you didn't use it on .

I guarantee all home mechanics who re fit exhaust studs overtighten the nuts.

I don't dispute that but i know thats not the reason they break. They don't brake on RB26s, only RB25 and RB30s , the manifold is so long ....

      Are you an oil nerd?

      I think the concept is highlighting the various scenarios where thicker oil helps, and thicker oil potentially doesn't help and only generates heat and costs power, in turn for safety which isn't actually any safer (unless you're going real hot). If anything this does highlight why throwing Castrol 10w-60 for your track days is always a solid, safe bet.

      Jason should have shown a real viscosity vs temp chart. All the grades have very little viscosity difference at full operating temperature.

      Steps to DIY sanding car back ready for respray....

      By Murray_Calavera · Posted

      Yep, if you are applying filler it sounds like there is something wrong with the body lol. Safe to assume there is going to be a lot of sanding going on if your still applying fillers.  Picture a perfect bare metal panel, smooth as glass. You lay down your primer, it's perfect. (why are you going to sand it?) You lay down the colour and clear, it's perfect. No sanding at all took place and you've got a perfectly finished panel.  You won't be chasing your tail, sounds like you were prepping to start laying filler. If your happy with the body after the sanding, there is some bare metal exposed and some areas with primer, no issues at all, start laying the filler. You are safe to lay filler on bare metal or primer (of course check your technical data sheet as usual for what your filler is happy to adhere to).  This isn't a 100% correct statement. There is primer that is happy to adhere to smooth bare metal. There are fillers that are happy to adhere to smooth bare metal. Just make sure you're using the right materials for the job.  Typically if you are using filler, you would go primer, colour and clear. I've never seen any instances before where someone has laid colour over body filler (maybe this happens, but I haven't seen it before). So your plan sounds pretty normal to me.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I don't think there's any way someone is push starting this car.. I honestly can barely move it, and moving it and steering it is just flat out not possible. I'm sure it is, but needs a bigger man than me. I have a refurbished starter now. The starter man was quite clear and consise showing me how nothing inside a starter really should contribute to slow cranking, and turned out that for the most part... my starter was entirely fine. Still, some of the wear items were replaced and luckily it didn't show any signs of getting too hot, being unfit for use, etc. Which is 'good'. I also noticed the starter definitely sounded different, which is a bit odd considering nothing should have really changed there.... Removed and refit, and we'll pretend one of the manifold bolts didn't fully tighten up and is only "pretty" tight. GM only wants 18ft/lb anyway. I also found a way to properly get my analog wideband reading very slightly leaner than the serial wideband. There's Greg related reasons for this. The serial output is the absolute source of truth, but it is a total asshole to actually stay connected and needs a laptop. The analog input does not, and works with standalone datalogging. Previously the analog input read slightly richer, but if I am aiming at 12.7 I do not want one of the widebands to be saying 12.7 when the source of truth is 13.0. Now the source of truth will be 12.65 and the Analog Wideband will read 12.7. So when I tune to 12.7 it'll be ever so slightly safer. While messing with all of this and idling extensively I can confirm my car seems to restart better while hot now. I did add an old Skyline battery cable between the head and the body though, though now I really realise I should have chosen the frame. Maybe that's a future job. The internet would have you believe that this is caused by bad grounds. In finding out where my grounds actually were I found out the engine bay battery post actually goes to the engine, as well as a seperate one (from the post) to the body of the car. So now there's a third one making the Grounding Triangle which is now a thing. I also from extensive idling have this graph. Temperature (°C) Voltage (V) 85 1.59 80 1.74 75 1.94 70 2.1 65 2.33 60 2.56 55 2.78 50 2.98 45 3.23 40 3.51 35 3.75 30 4.00   Plotted it looks like this. Which is actually... pretty linear? I have not actually put the formula into HPTuners. I will have to re-engage brain and/or re-engage the people who wanted more data to magically do it for me. Tune should be good for the 30th!
