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

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.

    • I know people cry at the price of the Getrag 12-14k for a conversion now, but it really is a nice mid point. Not going to get change from 10k on a gearset installed.  $30k++ for sequential.   I know you run the risk of a damaged used one and parts are hard to get but as a street car gearbox its really hard to beat. If you enjoy a more traditional manual, its the choice no question.
