Hi Paul, What vehicle, year of manufacture, model of vehicle? Are you referring to a Vanos system on a BMW or VVTI. What engine oil do you use in your vehicle and how often do you have lube services carried out? How old is the vehicle and has any other work been carried out on the vehicle? The more info you give us, the more chance there is of being able to help you. Regards John
Black smoke indicates too much fuel being introduced through 1 or more ports. This could be anything from a stuck injector to a bad ECM sensor.. even a clogged air filter (which would ****** the air, causing improper mix)
