My car is running really rich, however when I fire it up sometimes it spits out a lot of black shite. I assume this is just carbon deposits that built up in the cat. When I reved it before it was totally warm, it gave a slight puff of snow white smoke. My fuel pump is dieing and I intend on putting a new one in on the weekend and getting it retuned shortly after.

hmm white smoke, that doesnt sound good.

If your fuel pump is dieing you wont be running rich you would be leaning out, so im not sure why ur blowing black smoke, i get black smoke under heavy accerealtion due to running very very rich. also getting it when revin it abit when it just sitting there

Does it give white smoke everytime, u rev it when its cold?

all cars will blow white smoke before they are totally warm.. merely condensation within the exhaust system heating up and coming out.

if it blows white smoke after a say 10 minute drive. then you'l be looking for either seal on turbo or head gasket problems.

Ahh sweet yeah it was only really when it's warming up that I get white smoke, and black goo (which looks like pure carbon). After it's warmed up I get black clouds when accelerating. Thanks for that guys.

Do flames ever come out from the exhaust?

I think mine just had some carbon deposits which is why the fuel system cleaner got rid of it. Hit www.nulon.com.au and check out the fuel system cleaner.

Also, how does your oil look? and when did you change your oil last?

Black smoke on boost means its running rich.

so its not neccesarily something to be extremely worried about...like its not the engine dying etc...

he told me that with a turbo you want it to be running a bit rich...that accurate?

from what i've been told by my mechanic mate, grey smoke is more the car being cold, and condensation.

black smoke = burning fuel and white = burning oil...

so it doesnt matter if its black or white , its bad

lol

Close.

Black smoke = carbon, IE running rich

Bluish-white smoke = burning oil

Pure white smoke = burning coolant

As has been mentioned, white smoke during a cold start is normal from exhaust condensation.

i have a short video clip of a skyline idling...if someone is able to host it for me (its about 4mb) would you guys be able to tell me what the smoke is, and if its a problem etc...

or i could send it to you if you give me your msn

thanks for that mate...ok guys so i took that vid when checkin the car out...

it was on a cold start, ice cold engine basically, hadn't moved. had just been washed and was basically still a bit wet on the body. umm, that was just AFTER it had been revved n stuff. when it was revved that same color smoke just got a bit thicker...then died down to what u see in the idel vid..

so what are your thoughts? bad? nothing to even worry about?

      Strange issue RB25DET wont start

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.

      Yeah, I would have said the same. It makes me suggest that there are other things wrong, such that the ECU is totally unhappy with the broken sensor. The only other thought here is that maybe it is shorted, which might cause a different issue to the typical "disconnected" sensor.
