Black smoke when in high revs help plz !!

[abe]

I have a 2001 DC2 type r
when vetc kicks in light gray smoke comes out of my exhaust, but this only happens in high revs wen vetc kicks in.
I want to know if its a problem, or if something is wrong
Plz helps thanks

hey man nothing to worry about :) its just the excess fuel.

all vtecs run rich when engaged onto HIGH CAM (VTEC).. its just the excess carbon buildup and excess fuel being shot out the tail pipe :)

generaly speaking

White smoke: WATER in the combustion chamber

Blue smoke: Oil in the combustion chamber

Black smoke: burning fuel/ carbon buildup...

basically when you tromp your foot on the accelerator, particals of carbon buildup will shoot out your exhaust and will generally land on the rear bumper around your exhaust.

as long as your car is running well dont worry about it

Ok, first you need to distinguish whether it is black or "light grey".

Because they both mean different things. Black is fuel (running rich) and it's ok for a tiny bit to come out at vtec's final stage, Light grey sounds more like "blue smoke" which is generally oil burning.

Lot's of 90's honda's tend to burn a little bit of oil at top RPM on full throttle. I mean 6000-8000RPM is pretty high strain lol.

Check like this, check your oil in the morning or when the car is cold, go for a spirited drive and hit vtec a few times, when you get back let the car sit until cold again, then check the oil again and see if it's lost any.

If it is losing oil at high RPM it's most likely one of two things:
• The oil you're using is too thick or too thin.
• The valve seals in the engine head are worn. (this happens to older cars after a while and is pretty much unavoidable)

Best of luck in solving this issue. :)

lol I think we posted at the same time haha

Thanks alot guys made me feel better cos i just bought the car like a week ago. Thanks again cheers.
Oh lol i got 2 more question,
1. when in vtec and changing from 2nd to 3rd my gears crunch as im putting it in third but only happens wen in high revs. Also wen in high revs and i change quickly, when putting my foot in the clutch i hear like a thud noise in the clutch, i think it might be my engine mounts but im not quite sure? So if u guys can let me know what to do or whats up with my car?
2. What gearbox oil should i use???

[dc2r-0636]

are you sure ur clutch is 100% in wen shifting?? coz if u go to shift and ur clutch isnt in it will crunch.. might have to evn change ur CMC fluid..
maybe you just need new gearbox oil.. gota recommend OEM honda oils only for gearbox, power steering and brake/clutch fluid.
if that doesnt fix it might be your 2nd to 3rd synchros

i thought blue smoke meant water/coolant ?

and white was oil burning ?

[Alexplicit]

synchromesh is gone/going... means gearbox over haul... you could however try using a thicker oil.

I am i fond believer of Honda OEM oils... which you can purchase from your local Honda dealership.

If your a spirited driver, i recommend REDLINE LIGHTWEIGHT SHOCKPROOF...

PS: I use to own a swift gti turbo, and swift are renound for having absolutely shocking gearbox's and Redline lightweight shockproof got rid of my 1st to 2nd crunch... and also did the same for a few of my mates.

Reguarding the engine mount it would probably be your rear engine mount... easy way to check is to put your hand break on hard, get someone to watch the engine, then put car in first and release clutch and watch for engine movement.

you thought wrong, the last time you boiled your kettle what colour was the steam?

easy tiger

[Alexplicit]

lol i thought that came across a bit rude... sorry i didn't mean it like that...

[Alexplicit]

will u accept a virtual hug as an appology :P

[mnc]

I will accept the hug..... even though you don't owe me one :]

I recommend doing a compression test on all four cylinders both wet and dry and also a leak down test and then reporting it back here so we can help you out further =]

[tiah313]

i got the problem with changing froom 2 to 3rd too, and wht u can do is to double clutch it means 2nd > N > 3rd, this will fix the problem, have to do it real fast

[abe]

yea my car takes out gray smoke, but only wen vtec kicks in.
And my gearbox wen im in 4th gear and i want to drop it down to 3rd, it wont go in and if i try to get it in gear it crunches

[Alexplicit]

i believe when you have an issue with your car, FIRSTLY do a search, i guarantee you someone has had the same issue as you, secondly check everything you know how to check relevent to your problem.

in your case abe, firstly put some new oil in it. then tell us how you go

[tiah313]

same thing happen to me, its imposible to get into 3rd from 4th high revs. double clutch when u gear down too, acce abit when ur in N and go in 3rd

[Greatbigbeans]

I'm the person who's having the same problem.
I've bought honda MTF-06 oil for my gearbox. i can say that when vtec is engaged in 2nd gear, shifting to 3rd didnt stop the crunching. and its only when shifting in this sequence that the gear grinds/crunches. although it did make shifting other gears slightly smoother.
My mates and i were talking one night and came to a thought of maybe a short shifter could fix the problem. you could give that a go and see what happens.

you could possibly try what Alexplicit said and use redline oil and see how that goes. if you do please let me know how it goes.

[abe]

Thanks alot guys il give that redline a go and let u know how that goes

gota recommend OEM honda oils only for gearbox, power steering and brake/clutch fluid.

OEM Brakes fluid is crap, and the gearbox oil isn't very good either. All depends on what application though.

whats wrong with it ? i havnt had any problems with it.
what would you recommend.

[abe]

Is it normal for a Dc2r to burn engine oil?

[dc2r-0636]

B series tend to use more oil then K series. how much oil are u burning

[abe]

well i checked my oil in the morning before i took my car for a vtec run and the oil level was fine, then after the drive i let it cool down and checked it and the oil levels were the same.
so im not sure because it blows out like gray blue smoke and the back of my car is dirty with black dirt from my exhaust and it only blows smoke when in high revs vtecing .

[dc2r-0636]

i had a similar problem wen i got my car. no idea wat oil was in it but i changed to honda oem oil 10-30w and it didnt burn. still got black shit on my bumper over time.
now i am using castrol edge sport 5-30w going good. just change ur oil and oil filter (dnt use ryco use honda oil filter or k&n filer)

[tinkerbell]

(dnt use ryco )

what is wrong with Ryco filters?

[pablos8]

Wasn't picking a bone? I haven't ever heard of issues with Ryco filters so I was asking lol?

[dc2r-0636]

fair enough mate just seems like every one questions things.
coming off personal experience wen doing an oil change the ryco filter became loose after 2,500kms

Looks like its OEM honda only from now on for me lol

Been using Ryco the whole time, never had a problem

[dc2r-0636]

What car you been using the ryco on ?

[pablos8]

What car you been using the ryco on ?

Originally my EG but I have a DC2 now but I'm due for a service fairly soon so I'll probably use the honda oil filters and get some honda feo oil?

[dc2r-0636]

Try out the new full syn oil from honda

[abe]

well i just gave it a major service, i changed the oil filter spark plugs and used mobil super 2000 10w-40 semi synthetic engine oil, which i think is sit but didn't know at the time so yea.
A mate of mine said maybe its my cam seals warn out ????

[pablos8]

So its still blowing smoke?

You're probably running a bit rich or your seals are worn

[tinkerbell]

worn cam seals wont make you blow smoke out the exhaust...
