Hi my 1990 8v digifant golf gfi has developed a smoking habit my partner red lined it to 80mph in 3rd the car felt like it lost power and puffed out smoke for a few seconds I changed the complete dizzy assembly, cap,plugs,leads because it had trouble starting, now the car runs fine but is smoking whitish smoke smells exausty, no loss of any fluids it's not too bad when cold but gets worse when warming up. Any ideas or advice
