I get the same thing dude... I think it's an inherant thing. I haven't cleaned and sealed it up yet. I've looked this prob up before and people seem to say it is glued and you can unglue it by putting it in a WARM (not hot) oven for a bit to soften glue, then it just peels off... I'm not game enough to do this. Maybe wait till it's warm and the vapor has gone from inside, then just reseal the edge with silicone or something...

Well, hope you sort it out, it's a bit annoying hey?

cheers.

i know it is really annoying i hate little trivial things like that i have priced two new head lights the cheapest i can get them for is 520 and he will give me 150 for mine so 370 ea. Someone said something about using a heat gun to soften up the glue. Oven sounds to risky for me too hahahaha tnen i am worried about reseal them what can you use??

I'm not 100% sure what to use, but I'd hazard a guess that a mould resistant silicone that will stick to plastic should do the job. (Otherwise known as bathroom/kitchen silicone). Just read the back of the tube to make sure it'll stick to your plastic.

The heat gun sounds like a somewhat safer way to do it too... If I was going to pull my light apart, I'd go the heat gun over and oven!!

Anyway, good luck with it.

Oh, with the silicones, get one that dries CLEAR, not white!

cheers!

Ages ago a guy did a thread on this exact thing with heaps of instructions. I couldn't be bothered searching for it because I don't have the problem but I think he used the oven method with success after hearing the rumour that it worked then you use the black silicone that they use for glass seals, windscreens etc.

i will take some photos of where i drilled when i take my light out next. i have to spend a day servicing and working on my car so i will post some soon.

the only thing is that it still fogs up every now and then, but after drilling the holes the moisture inside dissipates alot quicker( a matter of hours). Whereas before it used to stay in there for weeks. i wish i knew how that moisture is getting in. I have never seen the OEM Xenon light set up. From what i can gather though the ballast is incorporated into the headlight assembly on the inside behind the low beams. Mine looked as though the ballast has been cut out of the bottom of the headlight asssembly and then a piece of plastic has been siliconed in place i think the moisture gets in from there ???

has anyone seen or have pics of the OEM Xenon setup?? anyhelp would be appreciated??

Next time i take the lights out i might try completely covering the part which looks like it has been cut out in bathroom grade waterproof silicon to see if that where it is getting in??

As for this putting the headlight in the oven business i really wonder if it works?? Not game enough to try this as a new headlight costs around 500bucks.

I've found that Maguire's 'Plastic X' makes your headlights look new and temporarily gets rid of the 'foggy headlight look' that most Skylines have. The affect lasts a while as well. I've also heard of the oven trick, but since finding this product I haven't really bothered researching further into it because the headlights come up clear enough for me. I'd be interested to know if anyone can get the light apart though! It would be great to be able to use this stuff on the inside of the light as well.

      spot the stagea

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.

      In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).

      ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.

      OK, if it idles at 1000+ with the AAC, its not an idle airflow problem. The cold start valve just gives extra air when the engine is cold, but you have enough air without it to idle at 1000. I think you are back to a fuel problem, sorry. Can you see the fuel pressure staying constant or does it drop as the revs drop to a stall?
