Hey all my name is Preston I don't know how this all works but I am a starting out mechanic non schooled just learn but watch and asking. Just got my 1st ever honda 98 civic ex d16y8 didn't know it was vtec til I looked it up two days ago had the car for about a week. So it sat up for about year and a half it was a older guys car he got but never drove so I worked on it for him changed oil cable cover vtec gasket clean throttle body and stuff like that before I got it but I just started driving it two days ago and notice when I accelerate white smoke comes out back but I haven't drove it three miles yet... Thoughts please
