unsure if its the standard clutch or aftermarket clutch in my 33 (hasn't been changed since i bought it, previous owner wasn't sure either)

i've noticed lately that now i have to push the clutch all the way into the firewall otherwise it crunches, I used to only have to press the clutch 3/4 of the way to the firewall... my mate says its the clutch fork boot. would he be right?

If it helps, i noticed today sitting at the lights, on a slight incline.. clutch in, in first gear, take my foot off the brakes, (clutch still fully in) the car rolls back the slightest bit but as soon as i give a little gas the car stops moving backwards even tho the clutch is still fully depressed.. If i dont blip the gas the car keeps rolling backwards.

Any ideas?

Also, i dont have the cash just yet to fix it, is there much harm that can be done if i drive it for another week or so?

it wont be the boot at all

either a pivot issue(often break), or clutch failure(pressure plate issue) of some sort, or bad adjustment caused by master of slave failure

maybe try bleeding the fluid for starters, first at the nipple on the master, then if still shit, bleed at the slave

let me get this straight, while the clutch is fully pressed, and u press the accelerator, the car stops rolling back, even if you have had the clutch all the way in the whole time?

as lotsalag said, won't be a boot issue. the boot is simply a rubber seal. i'd say it will either be an adjustment issue or a pivot bolt issue. i've seen a few skylines snap the pivot bolt (mine included).

there is a small chance the that actual clutch fork is bent, but i doubt it unless you have a super heavy clutch.

Air in the system, worn master/slave cylinder, pivot ball snapped/worn, or pressure plate worn.

If you can get under the car, pull off the clutch release arm boot and have a look inside with a torch. Get a mate to sit in the car pushing the clutch pedal in and out. Will give you a good idea what is happening with it.

yep.. so its like the clutch is grabbing the slightest bit (hence the car stops rolling back) so even with the clutch fully in, its still grabbing the slightest bit..

i dont get any clutch smell, gears dont crunch. The clutch feels quite heavy (same as my old car with a hd clutch in it)

will bleed the master/slave over the weekend.

What was the solution to this? i have the same problem :)

With the clutch pedal all the way in, i can either not get it into gear at all or if it does happen to (on occasion as it is temperamental), i roll forwards lol, while the pedal is still in.

Did this once and since had got the lines bled etc, has had new push rod and adjustment done and was all sweet for a while now its back to this again. ?? domokun.gif

      3D printing fun

      No worries at all 🫡 I think the most satisfying things to make are the little bits that are just impossible to find or they're no longer manufactured. Generally I always try to replace parts with OEM wherever possible. This little project is also great because it'll never see the light of day, but strengthen these brackets so it's not just relying on the little standard screws in the headlight plastic. As soon as I saw the standard brackets and screws I thought, "well I'm not going to install with just the screws, the plastic tabs will just snap off". It's crazy how expensive everything has become yeah. But I suppose that's supply and demand; granted it's a lot easier to get brand new genuine parts these days which is fantastic 😊, I don't have to get totally reamed at the local Nissan dealer ha ha We sure are lucky we have all these manufacturers making parts these days, a few really great Australian companies too like Platinum Racing Products and Fit Mint Automotive, what a time to be alive ❤️ . I've got my eye on the RB26 head by PRP as mine has a very fine hairline crack, so that'll need to be addressed some time in the future. If you have any requests or odd things to make feel free to let me know and I can have a crack at making replacement parts ✌️

      Thanks for sharing this, and BTW if your headlights are in good condition they are worth thousands....you might want to consider replacing them with brand new LED ones like this (https://www.nengun.com/78works/full-led-headlights-r32-skyline) and making enough profit to buy a house in Sydney

      R32 GTS (RB20DE) clogged cat

      By Duncan · Posted

      I'm not sure what sort of shops are nearby, but I'd expect any reasonable exhaust shop could put a cat in it that will not restrict the power that engine makes. Otherwise, if you want to remove it, short lengths that replace the cat are readily available online, search for "de-cat pipes" or "test pipes"

      Howdy friends, So another weird one today, I was looking into replacing some broken clips holding the front grille for the R32 GTR (part number 01553-03831), and noticed the brackets which are supposed to hold the grille in place were also missing 😑. I do recall seeing this issue many years ago, but didn't fix it at the time. A quick look on eBay and I was able to find the genuine brackets, along with all the screws which suited the headlights (part numbers 26042-08U05,26092-08U05). Happy days!....  Once they arrived however there was an extra nut in the packaging which implied that there should also be a bolt or a stud, and sure enough, after a bit of searching I found this thread from 2013, and @Ants clearly shows a stud should be present. Reading around a bit more, it's possible the headlights on my car are the "povo pack" headlights as mentioned by @funkymonkey in this thread way back in 2008. This could explain why the studs are missing on my set of headlights. Looking at the headlight diagram I wasn't able to see a suitable part number for the stud itself. The headlight did indeed have a recess that looked like it would accept a stud, but interestingly no thread or anything obvious how the stud would be affixed to the headlight, I suspect it may have been glued in, press fit, or melted into the plastic at the factory. Another member may be able to clarify if they happen to have a genuine set of N1 headlamps. The only thing we have to work with within the recess is a keyway which likely is there to prevent the stud from rotating within the recess. In any case, back to 3D printing, I put together a model which acts like a pug with a friction fit inside this recess, making use of the keyway so it doesn't rotate while tightening a bolt. Printing in TPU will allow it to slightly swell making a nice snug fit without cracking the part. I've designed the adaptor it to accept an 20 mm M6 bolt (stainless with a cap head in my case), as opposed to the standard M5 stud and I made use of the standard galvanised split washer that came with the genuine brackets from Nissan. Once the bolt and screws were all in place, giving the bracket a gentle shake gave the classic "shaking the car" feeling, very solid, which gives me confidence this is going to be able to hold on much better than the janky solution which seems to have been here for the past decade or so. Overall I'm really pleased with how this turned out and maybe there are more people out there running these headlights without a centre stud at all!

      R32 GTS (RB20DE) clogged cat

      By GabsReDeal · Posted

      Hey everyone, This is my first post apart of the introduction. I tried searching a bit on the forum but couldn't really get a straight answer. I got the car to my mechanic as I felt it being weak. It seems that it was missing on two cylinders due to the injectors. I had all my injectors clean and the car runs much better. The mechanic also confirmed my suspicions that the cat is clogged and needs to be tackled asap. The cat rattles a bit and the hot exhaust warning frequently lights up when driving after getting the injectors clean. In my introduction I was asked about what modification I might be interested in and mentioned a cat delete. From what I was told, this is not really beneficial on the RB20DE and there are more cons than pros.  Could perhaps anyone give some suggestions on what the best course of action would be since the current cat is toast and needs to be removed/replaced anyway? I can also sometimes smell a strong smell of fuel, but I'm not sure if this is related.
