Black Smoke

[shmiddy]

got a new bov otherday, and today i wacked it on and was adjusting it, i think it was a bit loose as the idle was up and down a fair bit, anyways i took it for a spin and getting up the street it became really bad didnt really wana drive juste idle serge, only traveled 200m odd, anyways i limped it home, and tighteded it up and got it idleing normal, but i have noticed its blowing a little black smoke, as i tightened it up more, the smoke got less and less, now i DID do a search on it and i found black smoke usualy means running rich, and my car runs slightly rich but can my bov's spring tension effect how rich it can run??? im a little worried to drive it now, no performance loss or anything, all idles the same now just a slight haunt of black smoke now, any ideas?

and yes i will put original bov back on tomorro

cheers guys

atmo bov or recirc ?

[shmiddy]

atmo mate, and unless i have it that tight taht it wont vent proply and get flutter, when it was idling like a pig it vented awsome, but its that tight now i get reversion, my old bov was the same and was tuned with reversion and really tight , but it shouldnt really matter should it

atmo = rich...

Did you block off the hole where the stock recirculating BOV vents back into the intake?

The amto bov should make no difference at all until you back off the throttle...

Unless it's open the whole time in which case it'll do what you're saying.

Turn you engine on, open the hood and look at the bov.

Pull lightly on the accellorator cable to rev the engine and see if the bov is opening. Don't rev too hard only a little. If it's opening it's too loose.

[shmiddy]

yeah cheers for replies guys, if the bov is opening and it is causing it to run slightly rich, would it harm my engine?? asin would it be right to drive to the shop and back?

[Craved]

running rich wont harm the engine, perhaps may foul the plugs a little, but that easy to clean off. get someone to check it out. ive noticed that some cars react more to atmo BOV's than others.

[lordsnipe]

i bet you haven't blocked the recirc piping.

the rubber hose that the stock BOV was plumbed into has to be blocked off, otherwise you got a leak right there.

got a mirror out and looked at the valve as i started the car, and as the car started the valve lifed so it was venting air, i put my ssq back on and it runs good as gold again, so tomorro ill put in a heavier spring and see how i go, cheers for replies guys
