There seems to be alot of info on how to restore yellow headlights online including sanding and polishing but none of it seems permanent and does not always come up 100% and I know most people are not going to want to spend huge $'s on new headlights so.....

Please let me know if the following idea could work:

Would it be impossible to get a mould made up of the headlight cover (with the clips as one piece) and have a batch made with a plastic moulding company? Does anyone have any connections or anyone in the industry that could give us an idea of how much it would cost or if possible? If one person were to invest in the mould and get a batch made up then I am sure that there are alot of Skyline drivers out there who would be happy to pay to have brand new clear headlights that won't re-yellow for a few decades at least (and a bit of a profit for the person willing to get the project going). The only catch would be the re-glueing of the halves together again.

Thanks, KTV

I've tried PlastX and it didn't do jack for my R34 GTT headlights (or anywhere else for that matter) .. is there a place in Sydney that does headlight restoration? I know Final Inspection in Melbourne does it and I've seen some pretty amazing results

My R34 looks like it has small stress fractures more than 'yellowing' so I'm not actually sure these can be restored.. so it'd be good to get a professional opinion.

what it is, is moisture getting inside the headlights, i had that problem too and like the above post said, every now and then just cut n polish it will look crystal clear for a few weeks.

i agree, your prob must be water on the inside of the lense, i have alittle bit on the inside of one and plastX makes it better but not 100%...

for the other headlight that doesnt have any leaks (yet), platX makes it look brand new

also ive never don it but to open the lense your meant to heat it up in an oven to melt the glue, then clean the inside of it, and re glue it..... i recon its risky if you forget the thing in the oven and you melt the whole thing lol

DID ANYBODY READ THE ORIGINAL POST???

Polishing and sanding only seam to be temporary repairs because the yellow comes back and the plastic is still deteriorating. Wouldn't it be better to just replace the plastic lense so it looks brand new for years/decades?

Does anyone know of a plastic moulding company that might do this in Brisbane? I will look into it.

KTV i hope you find what your after mate. I see your idea your after but i hesitate to believe it will work either.

The current lights are lexan plastic suitable for the job but it like almost any other clear plastic is subject to yellowing. Mainly on the outside but some have evidence on the inside too.

As you know you can polish them with just about any polish or compound, and its as you said only temporary. The latest hype, "Glassylite" product they claim works much longer so im looking to try that out soon.

Maybe if your looking to mould a new face you should be asking can a glass guy remake the face in glass??? Now that'd be an idea... Let me just say the first person to make a replacement unit for r33 & r34 with glass lense will make a fortune worldwide...

Are you saying you'd remove the current plastic lense and replace it with a new mould? That'd still involve taking it apart, so perhaps you could try cleaning the inside of the current lense with a cut and polish and resealing it (stuffed seal is probably the problem any way) before you go and try recreating everything.

I think you'd get close to the cost of new genuine lights having to design and fab new stuff. Also don't think you'd get any where near good enough quality and/or replication of the genuine items.

Had mine done 3 years ago and they are still crystal clear. My painter cut and polished them then applied (i think) a two pack polyurethane clear over the top. So it must be an oxidising problem that happening to the plastic.

    • 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!

    • 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.
    • Hope the cans went down well at least 
    • 255 can't go wrong with the price.
    • When I was replacing my pump due to being stranded in the wrong state, I went with the Deatschwerks 320lph kit. It is a direct plug in to the stock wires, harness, everything. It comes with a plug... but you can plug the OEM plug directly into this thing. https://justjap.com/products/deatschwerks-dw300-fuel-pump-nissan-s13-silvia-r32-r33-r34-skyline-c34-stagea?currency=AUD Downside: Won't actually flow that much on boost if you want to push it on E85, but it's comparable to the 040/255 etc. Little more actually.
