My car has been laid up for the past week whilst a fitted a new mani, decat, turbo. Started her the first time in a week today. My first q. How much white smoke should I expect from the exhaust after 1 week. On idle and with foot down but static before running ok? I know therell be some condensation build up........ Second q. I,m getting some smoke from the mani area. Is it a case of not tightened enough and its fumes or possibly crap being burnt off the mani etc
