Smoking On Warm Start Up?

I only smoke when my car is cold.

But, if you have some smoke, how long has it been happening? If you have worked on it recently, it'd be grease or oil burning off as it gets hot. Even a dirty hand on a dump pipe can make a noticeable amount of smoke when the engine is hot.

Is the image supposed to be related in any way?

hi there the image is just of my mate sticking his head in the way as i was fitting my FMIC ,as far as i know its only started to happen about 6 weeks ago ,it doesnt blow any smoke at all and runs good on start up when cold but after running for a while and i stop then hop back into car and start it up it doesnt want to start straight away when it does a puff of smoke comes out of the exhaust and thats it ,you can rev it up and get none ,it idles good and has full boost ,only owned the car for about 5 months if that really happy as its my first r32 but its only an auto but breaks traction in first three gears which i thought was bloody good so im bit concerned about this i dont drive it very hard at all as it has new tyres etc

Ah! Different story! I thought you had smoke in the engine bay or something... so that pic is completely unrelated in every way to the question. =-p

Ditto to Green s13... I wouldn't worry about that. You'd get plenty of that if you back off at high revs. Exhaust soot, basically.

what colour is the smoke, you say it doesn't start straight away if the smoke is black then it is just unburnt fuel from trying to kick over

smoke colour is bluey white only comes out ater its been run then turned off for a while then started then puff out it comes thats why i thought it mite be valve seals like oil getting into engine when warm then it gets burnt when started also in the last week or two ive notice black bits like soot on my back bar after given it a gut full on the way home from work

      This is a story of my life things, I learned eventually (thanks to someone calling me out) that my enthusiasm for discussing and sharing ideas that it came across as arrogance and I'm like... WTF?!    One thing I'm pretty sure I justifiably pride myself on is knowing that everyone will have things they can teach you, and you're always going to find out that something you think you know turns out wrong - you just don't know what it is until you get there.   Just the bursting enthusiasm that comes with ADHD when you hit something that gives you dopamine dumps can come across like you think everyone else is wrong or don't matter. But yeah, I'm a software engineer by trade and also do tuning in weekends and 100% have long had a reputation for  quickly making connections when resolving problems or forming solutions that I've sometimes had to take people form a long walk from start to end to explain how I ended up where I did when it's seemed "too simple" when I've stated my initial case, and had the "WTF" type reaction when they've realised how much was actually considered haha.   My reward is that I get all the curly problems thrown at me.

      Wives never seem to find things funny. Especially when they're trying to sleep, and you've found the new funniest thing ever. I've never seen someone be able to get try and be cranky with me, while they're holding back fits of laughter... 😛   Also, I tell mine it's payback anyway. She has BiPolar. So the household can get quite emotionally wild at times 😛

      I'm not up to date on the latest, but for basic modifications like pod filter, lower springs etc you can get a modification permit at the time of inspection.  For more serious modifications you will need engineering.  Intercoolers used to fall into the mod permit rule but its been a long while since i looked it up.   Either way you will be able to get it registered, just a case of $300 vs $3k .

      Hi everyone! I’m the new owner of a 1996 R33 GTS-T, I’ve purchased this car over from Queensland and brought it to Western Australia and I’ve found that there is a hole cut out in the engine bay for the FMIC that enters into the wheel well (fender liners are in the boot). For anyone that has had to get their car over the PITS here, will this be a major issue?
