i hate to post this again, but no one answered last time.. just finished up the h/c/i a few days go and the new valve covers i got need a breather instead of the filler neck with the hose going to the throttle body.. well 2 days ago i noticed that there was a little smoke coming from the breather at idle, and just a little more when i rev it up.. theres no smoke coming from the tail pipes, and everything seems to be ok.. should i be worried about this smoke? is it normal? ive never had a breather on my valve covers so i dont kno if just this little bit is ok.. thanks
