DC2R blowing black smoke

[Page]

If you go to a half decent workshop they should have a protable air/fuel meter. Just get them (or you) to do a quick lap to check the mixture reading at WOT

this sounds like my car!

after the tune.. it's blowing less black smoke.. but it's still blowing blue smoke (deaded oil rings around the piston i reckon)

then your valve stem seals might be on their way out...

[tinkerbell]

or your PCV system is busted (not just the valve)

damn..i just read this ...

is the car stock????????

if its burning oil, and you have aftermarket exhaust, it will be one of your probz, considering you have changed pcv, fuel filter and the rest of the things you mentioned......my car was the same, btu i had headers and exhaust......hence, not enough back preassure and it blew the oil out..........i got vafc tuned, and it solved problem a little bit, but now that its boosted it has a heap more back pressure and doesnt burn any oil at all.

good luck

MY DC5R if the ignition doesn't show the battery light and i start the car and when it starts it burns the engine oil... but it rarely happens, and most of the time if it doesn't show i just take my key out and stick it in and its fine...

just wondering is this a big issue or not??? I'm running a k100 tuned with injen CAI, toda manifold.

when running fine,... at about 7800 it blow i bit of smoke.. but i was told thats normal..

have you raised it with your tuner?

doesnt sound like a big issue, more like something easy to fix!

hey,
my problem is that my car blows heaps of BLACK smoke when i hit vtec
its to the point where i i can cover the car behind me
what could be causing my car to run so rich?
i am also losing oil,i've done a compression test
and leakdown test and everything is fine..
i've swapped o2 sensors
replaced pcv valve
what else could be my problem?

OK. how can i put it.

is the smoke black or blue? black is fuel, blue is oil...

if you are burning oil :
The leak down test is normally done with piston at TDC. Ask them to do again with piston at middle and at bottom.. Cause TDC does not detect issues on the middle and bottom of block. only detects issues with rings and valve seals etc.

If this comes back perfect and they done it properly than its just oil slugh to your PCV, whcih shouldnt happen much with street driving..

then your valve stem seals might be on their way out...

yeah but the trustly mechanic said the leak down was fine... but do u trust mechanics?
