New Owner - White smoke?

[Alex H]

Hello Fellow Skyliners...

Just purchased a 96 Silver, series 2, r33 with larger exhaust and 18 inch rims about the only mods. The car is auto - not what I originally wanted, although when driven - still amazing fun.

I do have a question for the more experienced campaigners...

After nearly red-lining in 1st - 2nd - a swirl of grey/white smoke (not always) is expelled from the exhaust - usually happens when I lift off the gas... I am assuming that this is a whole load of fuel being dumped - but wanted to confirm. Is my car a 747 dumping fuel on the ocean before landing? Or was my car born to me with a slight handicap of sorts?

I would say its jsut the car running rich the reason for this is the car has larger exhaust.

but I would get it confirmed by a work shop. as running rich smoke tends to be black

cheers

and I hope you enjoy

if it was fuel it would be black smoke.

Isnt white smoke from water? Does this happen when you first drive your car or even after its been driven for say 1 hour?

It usually happens on cold mornings as condensation in the exhaust system gets evaporated.

Ok - def white smoke - not usually after rain... Although, after car warms up and shoots a couple of loads - no longer really evident.

Thanks for advice, will def check out with the boys at Garage. Just having too much fun to worry about it at the mo

Did reset the ECU the other day - fuel consumption has dropped and less of the smoke'n...

Condensation??? Hmm - the exhaust is rather large?

Cheers.

i hope its not turbo seals , take it to a long downhill engage low gear say 3rd so its fairly high rpm 5-6000 stay off the gas pedal when you get to the bottom of the hill then push the gas pedal and watch in the mirror if you get a cloud of smoke either blue of grey whitish its not good . depending on the colour ( grey , white turbo seals ) blue =rings and or valve seals .

ps make sure engine is normal temp not cold , any black smoke is unburned fuel .

Don't want to be too negative Alex but i don't like the sounds of it. Get a leakage or compression test done as soon as possible incase it's doing some damage. I had the same problem with my R33, blowing a big cloud of white smoke when i eased off the gas after giving it some stick. Initially thought it was a blown turbo, then found out ringlands in one cylinder were f*cked. Hello $$$$.

Worked out that there was a lot of blowby in one cylider causing the cloud, but as the pistons heat up and expand, the problem doesn't seem so evident. Full rebuild in the process for me. Hopefully get the car back this week.

Hopefully for your sake it's not so bad.

Good luck

Same happening here Steg33

pulling engine out this week.

Good excuse to get forgies and a new turbo tho Cameron!

That's the only good coming out of my rebuild. If you're gonna do it, may aswell be properly!

Yeh sounds like worn rings to me, just what the other have replied. Bit of a bastard problem as engine will need fair bit of work and labour.
