update, car has stopped smoking as drastically as it was doing but is still smoking, left it sat for a couple of weeks and when i started it up it ran lumpy and we found a load of oil and crap on the bottom of plug 4, so put another plug in but and it ran better but started smoking a bit more, but still not as bad as the original problem. So ive found a new garage closer to home and its going in on friday for a compression test etc, not going to bother guessing any more just gonna find out whats up with it.
To make matters worse my misses focus just threw the crank pulley off, so no car at all now
