how come every thread on here about cars somking theres always people just shouting out yeah its your valve stems, no its your piston rings, no its fuel cut . all your doing is making other people pick up on this and then they decide to say the same things in the next thread about a smokey car. no offence to anyone ,i know there are a lot of people in the know on here but its too hard to tell without having a look at the car. ITs ok to point people in the right direction but can you really give a diagnosis on a problem without seeing it or without getting a detailed description of the problem? it could be a whole host of things do a bit of research and start ruling things out 1 by 1 until you get to the bottom of it but because you have a little bit of smoke doesnt mean you have a major problem
