If you use shell optimax, this is very normal.

I get smoke from BP Ultimate (this is all i have ever used)... and noticed under my tip there's black stains.. but I'm assuming this is normal from hitting vtec

This is quite normal for High RPM engines... I had the same thing when I owned a coupe Vti-R... Same thing happened with my mates 20V corolla above 5000rpm

I miss Vtec!!!

same here :thumbsup:

Theres nothing wrong with blowing smoke. Only if its real bad then you will have worn your piston compression rings. But yeah a little smoke is ok. Im used to it but just keep an eye on your oil level.

Guys... 'theres nothing wrong with blowing smoke - or its quiet normal over 5000rpm' type comments are actually incorrect!

YES - high performance motors will blow smoke - but it will very likely be 'black.bluey' colour which means there is ALOT of fuel going through the injectors which is normal for those cars.
On stock/mildly modified cars - blue smoke means your tune is a bit out - possibly a leaky injector, retarded timing etc.

On a STOCK car (which by the sounds of it this is a Stock car) - a WHITE coloured smoke means its got worn rings on the pistons and its letting oil through - it will only get WORSE.

A little smoke may be disconcearning but it shouldn't be ignored! Sooner or later this small smoke will be a puffing steam train and a cause to getting pulled over and having a working order put on the car.

How many KMS has your car done? and what type of oil are you using?

BTW: this isn't a comment to start a flaming game but its just bringing attention to the fact that 'smoke' out of the exhaust isn't a good thing in how ever amount it occurs and shouldn't be ignored.

Guys... 'theres nothing wrong with blowing smoke.

stock cars will blow smoke on cold mornings too. Mine did it with the old B16A2 with less than 50,000kms on the clock.

my 2c.. im not a mechanic or anything..

i get a lil bit of black smoke when i vtec it... i spoke to a few friends and honda service who told me its normal.. just my car is running rich (which was covered on the above posts)

i was told if its white.. then its bad. So if it is.. go get it checked out!

You will get a small put off Black.Blue fuel smoke when hitting vtec - its because the valves open up more for longer - more fuel goes in than its burnt - thats normal.

Adam - thats NOT smoke - thats CONDENSATION inside your mufflers... dont mix the two.

[ILLIN]

Thanks for the insight SINISTR... I'll keep it in mind next time I buy a VTec or i-VTec...

I actually noticed that my B16A2 consumed a bit of oil... I would've had probably less than half by the time I serviced by car which was at 5000km intervals...

But Rob (Hanny's) told me it was normal for me to blow smoke...

I miss my EM1.. EK1 just ain't the same...

duh .. lol ! but you're missing the point mike. :)
What we know as condensation may be considered as smoke to others. Im just letting him know that sometimes its not as bad as you think. :thumbsup:

don't you think tho - if you're giving that type of advice you should mention maybe that 'condensation smoke is ok' rather than just generalising and saying 'a little bit of smoke is ok'...

I had my mum and another friend call me at work on seperate occasions and tell me i was blowing smoke when i drove off in the morning. These were cold mornings when i parked out on the road many years ago. Some people dont know the difference ..

Id say your car is constipated!! :D

no idea...

[waymad]

i have done 160000 on my engine its running fine no problems but i did notice when iam in different car and my car is in front of me that my car does blow smoke but it only a puff of black smoke i think and my mates h22a does the same thing when vtec cuts in i use honda high performance oil

[T-onedc2]

Yes it's quite normal, can be two reasons, cabon build-up in exhaust if not revved hard for a while will all blow out at once, but I think most engines especially performance engines are programmed to run richer at higher revs under full throttle to reduce the risk of leaning out and causing detonation which can damage pistons and ring etc.
Someone please be kind enough to correct or confirm this please,
Thanks:)
