Yes guys it is an rs turbo escort and it has a stainless exhaust.

I tend to agree with the condensation but the only thing that was puzzling me is why it goes away and then comes back even when i have not restarted the car

could be siiting at the side of the road ticking over and it will be there. then go completely and then 10 minutes later be back

Thanks for all the replys guys. maybe i will just have to put up with the problem, I can just see the people coing to look at it wondering why its smoking though...
