Mine is a 1989 1.6 pinto, failed emissions when I went for Iva recently and he checked for smoke so I would get it checked beforehand if I was you. Also I would recommend you download the Iva manual from the government web site and go through it throughly. There is also a guide to passing Iva on gov.co.uk. Take loads of pictures of the stuff you can’t see. Its a long day and expect the unexpected, I was asked for pictures of applying lock tight to brake components (callipers and servo) and seatbelt fixings so be prepared. Good luck
