but its not using any water... so i dont understand how it could be any water related issues... :lol:

if someone could explain how the water level in the radiator isnt going down and yet its a water seal somewhere, id be more than happy to listen and learn... :cheers:

well, checked the injectors out today and no leaking from them...

had a look at the spark plugs at the same time and this is what they look like: (cyl 6 to come soon, but basically like cyl 2-5, ie completely black)

cyl 1: http://www.forghani.net/forum/files/imgp0955_114.jpg

cyl 2: http://www.forghani.net/forum/files/imgp0956_685.jpg

cyl 3: http://www.forghani.net/forum/files/imgp0957_194.jpg

cyl 5: http://www.forghani.net/forum/files/imgp0959_137.jpg

cyl 6:

something interesting to note is that i started her up and let her idle for a while, and its was perfect... not a problem at all...

then i started reving her and it was all fine...

then about 30secs later all the problems came back... misfiring on idle and smoking...

and then this problem stayed even after i turned the car off and let it cool down and then started it up again...

something else to note would be that the smoke is now grey/black... no white, no blue, no green, no purple... just grey/black...

soooooooooooooooooooooooooooooooooo, now that the injectors, fuel reg and fuel pump have been ruled out... what other fuel things can i check?

is it possible that the ecu has a f**ked up idle map but a normal map for anything other than idle?? sorry, i just dont know how the ecu/maps work... :thumbsup:

thanks

ash.

What ecu are you running? (sorry if you already stated this)

Looks like you have a VERY rich idle or even "start-up" that is fouling the plugs. Could also be O2 sensor, afm, afm plug/loom, wrong spark plugs, wrong spark plug gap (try 0.8mm), maybe even coils.

put ur hand over ur exhaust when it does this, get the smell on ur hand. and smell it. does it smell like oil? fuel?

old skool mechanics

my mrs had this civic right, started playing up a bit, blowin a bit of white smoke like this, checked the water for bubbles or oil, checked oil for water, checked comp, checked fuel, it was starting to over heat. everything looked fine., etc. changed thermo stat. etc. then one day.. warp. goes the head. .. was a head gasket, on its way out, just a slight leak and it cooked the head. and didnt give off the usual tell tail signs. only the overheating which was never really bad, only just over half, untill the night it went.

I learnt a valuable lesson that night.... im no mechanic. haha don't know how this will help you though.

but if i took a guess from what you have said, Depending on the smell of the smoke, i would say turbo or headgasket.

well, i'm not too sure...

i was told when i bought the car that it was a skyline ecu that had been chipped by dr drift...

BUT, i took it to a guy who fixed up all the wiring for me as it was a nightmare and he said he reckons its not a skyline ecu at all... its a cefiro one.. :thumbsup:

so i have no idea...

cant be coils as they are brand new splitfire coil packs... spark plugs are iridium plugs (not sure on the gap, but i'll get it checked out)...

doesnt sound like its the afm.. i've heard what they sound like with a f**ked afm, and mine is nothing like it...

it could be the o2 sensor in the dump pipe because at one stage i had raw fuel going through my exhaust/turbo, so maybe the o2 sensor has f**ked itself...

definitely smells of fuel and not oil..

the car doesnt over heat at all... and its not using a drop of water at all...

but thanks for the suggestion...

Just know, that a afm that is playing around will cause different faults. Just because you heard one that was farked, doesn't mean all do the same thing.

Your afm could be slightly worn, thus still working but not properly, and may be sending wrong signals to the ecu. I don't know, just saying don't strike it out as a possibility.

I think the misfiring maybe from low cold cranking amps i.e. the battery maybe on the way out, thats if it's not misfiring after say 10mins of driving. Or because of the fuel issue.

The white smoke could be caused from a number things all fuel related, low compression from worn valve stem seals, glazed pistons/bore, worn rings etc. or faulty fuel injectors, junked up, old etc. or incorrect fuel injection timing/duty cycle - if your tune is already rich(safe tune) start up is going to be ultra rich. Try the easy solution first, adjust the screw on the iac valve, this lets the motor run a bit leaner on startup.

Black smoke also fuel related. I don't know how you could rule out injectors without taking them out... Trying running some injector cleaner through the motor.

you know what... after about 10mins of driving it does actually start to clear up...

i dont know of this IAC valve, but i'll do some searching...

well, i just ruled out that the o-rings on the injectors werent faulty cause it doesnt leak fuel into the engine... what you're saying is right though... i cant fully rule them out unless i take them out and get them checked... but i'll try some injector cleaner first....

thanks for the info... :D

  • 3 weeks later...

just to finish off this thread....

the whole problem was a simple fix... it was running the wrong ECU... it was running a cefiro ecu instead of the skyline ecu...

and the mechanics i've spoken to cant explain to me why it was running fine and then over night it f**ked up...

either way, i dont care.. its fixed...

thanks for everyone's suggestions... :(

    • I am getting the same issue. Did you resolve it? I just got it after installing my new super coppermix and literally the same issue, new fork, new 18mm carrier, release bearing that came with the kit and replicated the exact same sound. 
    • If you like - I have the STL files so I can email em. There's a couple of gotchas (i.e the holes are not threaded so you might need/will need) to utilize some M3 melt-in threads for some of the points. However if you want to be super accurate, and are willing to remove your calipers and your SHOCKS it's a really good tool. You also might need to scale the part that measures the tyre width a bit wider. It defaults to a 7.5in tyre and I mean who is running that. Luckily with the magic of CAD this is very easy to rescale.
    • jeebus. glad you weren't under it while performing the stunt. Also thanks for the link to the wheel measurer, exactly what I needed
    • In the older stuff there were very significant differences 2wd to 4wd, for example Stagea had strut front end for 2wd and double wishbone for 4wd so it was not minor to swap. From poking around the 2wd v37, it *looks* like it might be more possible; some of the parts specifically have "2wd" stamped on them which suggests the platforms are more similar. You'd still want to start with a 4wd half cut to swap stuff from though. I'd suggest if you don't have a tune on the ECU you don't really need one on the trans either. Throttle mapping is in the ECU side (and you can always use a Roar Pedal if you want the throttle to actually respond to your foot), and really if you are happy with the stock power you probably accept the stock trans behaviour too....its all made to be "sporty" not racey.
    • So, updates. I have not washed the car since it came back from Tassie. I've driven it around a bit but not got around to actually sorting it out. I DID raise it because I cracked the rear bar leaving a hotel which was very distressing. Interestingly, the car drives more compliant now that it's raised a fair bit (5mm front, 15mm rear). Also noticed that my FR height was 10mm lower than FL. So that's now sorted out, too. I also bought this and had it printed: https://www.etsy.com/au/listing/1576422240/wheel-and-tire-fitment-tool-universal?ref=shop_home_feat_1&dd=1&logging_key=08f604d9fa4cc383550ba985e6ac85cd5cac7fbb%3A1576422240 Now, if I was smart I would have taken my brake calipers off to actually use this correctly but it was evident enough to me that in the region where the caliper was... there was nothing to hit suspension/guard/arm wise. So I'm going with "it'll be fine" after using the tool to hopefully very precisely measure the wheel clearance. Also while doing this, I had the very VERY bad idea of jacking one of the wheels/suspension arms up while the rest of the car was on jack stands. I did this to see how the arm would travel. This all was well and good until the car slid off the stands and went through a fence. So don't do that. Incredibly nobody was hurt and there was only minor damage to the rear bumper as the car didn't have far to slide, and had 3-4 wheels on it. The only damage turned out to be the fence itself which was easy to fix, and a little bit of damage to the fibreglass rear bumper trim. I had already planned to try a touch up paint kit to fix the time I drove into my garage door to see if it'd help in the interim before I get it fixed properly. I used the Dr Colorchip kit after looking online and seeing everyone talking about it. Yes it's made for chips and not huge broken missing pieces and I'll be 500% recommending it for stone chips after using it for stupid things like me. This took about ... 10 minutes and looking at the half assed photo the 30 second job I did on the bumper corner was almost perfect just by using the tiny little brush and painting it in. The sealact stuff to remove over-painting is really useful, so if/when I do it again I'll likely slather the touch up paint well over it and then clean it up with the cleaning solution. The wheels should arrive in a couple of weeks. I am still kinda confident after doing a stupid amount of measuring (and borrowing a set of 18x10.5+15) that they will not fit because I overlooked something, somehow and flew too close to the sun. ALSO R34 GTR guard liners do not fit on a GTT. I bought the undertray brake duct guides and had the wonderful problem of them not fitting my intake, my oil cooler and the liners themselves were even worse. Attempting to fit them won't work in general - You would have to cut them up as another poster mentioned as the bodywork is different on the GTT. At least I can try to resell them. So instead of cutting those up, I cut up my old already-cut-up GTT liners and extended them by using some PP plastic and drilling some 8mm holes for some nissan clips for the 'extra' bit. Because I was happy to cut them I was able to mount them pretty damn forward so I now have some semblance of guard liners, and the brake vents seal the bumper from the bottom. It sort-of-looks like this, to give some idea - If you look at the GTR and then the GTT this is when I realised that I needed to seriously measure as the inside of the rim area is entirely, entirely, entirely different and could not take any internet measurements for granted.
